Min of 55.4f/13c and a high of 74f/23.3c with 45% humidity. The highest temperature so far this year. It was cloudy this morning however all afternoon it has been sunny. It's currently 8.40pm and the temperature outside is 67f/19.5c. The weather looks terrible tomorrow however the rest of the week isn't too bad. The max UV was a 7. The highest temperatures on wundergound were in west London.

Pretty decent Sunday ( 87-93F around Chandler atm ) ..And yes, it is actually Sunday, lol ( ...The " My Brain had convinced me it was Saturday, when it is actually Friday " mind blowout the the day🤪 )

Little warmer than the last few days, but nothing near how hot it can be / often is by now..  Warms up to start the week, before another quick cool down mid week ..before the temp. Thermometer gets kicked up a notch as we head for mid month..

While still about a week out ..and subject to major change, at any time between now and then,  it seems the signals suggesting a period of potentially interesting weather ahead are getting a touch louder.. 

Current longer term  " thoughts from the CPC..  As usual, while the prospect of  -any- warm season rain / storm activity here may put a big grin on my face, everyone also knows i take all 6-10 /8-14 day outlooks with many grains of Salt / healthy heaps of skepticism.

Interesting tidbit in one of today's forecast discussions..

1379671565_Screenshot2023-05-07at15-53-51AreaForecastDiscussion.png.8a60c1a2d482a0869a225bbff894121e.png

That said, the potential precip signal depicted on both outlooks the last few days is a bit attention getting. True, rainfall totals this time of year here are minimal -at best-  ..so it wouldn't much of anything to qualify as " significant " rainfall.  When similar looking precip maps occur in July, Aug. or Sept., the current potential anomaly signal might point to a period of  wet / hot / stormy " Heart of an active Monsoon " - type of pattern ahead..

  In this case, though the chances of anything close to that occurring pretty low, such high anomaly possibilities are worth watching, even this far out..  I doubt we'll see much of anything, but ..I'll leave the door cracked open jusst a little -just in case, even this far out.

Heat returns, here, across CA,  and the Pac. N.W.  which could sizzle ..a little,  for a couple days at least.

Going for a warm 25C after a low of 13C but for most of the night it sat around 16C. We had the fire going and it was much too warm for that. We roasted through the night. We’ve got a bit of rain coming then we continue the descent into winter.

It got to 25.4C today and we had a few heavy droplet showers with really black clouds but they only lasted a few minutes so we basically got no rain.

Not much has changed. Sunny mornings, rainy evenings. Very gloomy with mild nights. 19.5°C this morning at around 8 a.m.. High of 24.2°C at around 2 p.m.. Thunderstroms in the evening and now it's been pouring for hours. Forecast looks similar. Things might change around the weekend. ☀️⛈️🌴

72F at 11:33PM, headed to a refreshing morning low of 58-61F tomorrow around town/ majority of the Low deserts.  Side-swiping low pressure area passing east / northeast across the AZ / Utah border will usher in perhaps the last, non-rain cooled, sub-90F day until at least the start / second week in October..  Heat rapidly builds again starting Thursday. Upper 90's to about 100F by Saturday onward.

Longer-range forecast still looking interesting starting Saturday, until -at least- the middle ( or end ) of next week. We'll see if we manage to get any of the showers / storms forecast for the mountains /areas south and east of Phoenix to move down into the lower deserts. While not a legit Monsoon -type of set up, with what is looking to be a fairly generous influx of moisture north from Mexico, and west from west / south central Texas ( where it looks WET ) it certainly will feel Monsoon-ish.. Heat will be in full force, though not on full tilt ( ...those infamous 108-110+ days before it rains kind of heat ) and Humidity / Dew Points which could be flirting with Monsoon-level #'s ..for a couple days at least.

Moisture looks like it will make it west to CA, though how much- if any- possible shower /storm activity might occur beyond the Sierras / Mountains over far N. Cal. is still in question.. There might be an impulse which manages to bring -something- closer to the coast, perhaps more in S. cal tan other areas, but, just as possible it is just warm / humid w/ some warm season cloud candy..

If the 00Z GFS is to be believed, once the unusual Wx pattern setup for the west over the weekend / next week ends, the long road of 100+ days will finally arrive and settle in,  just in time for Memorial Day Weekend.  Nothing unusual there..  Hopefully the wait for Monsoonal relief won't be long, or non existent  this year.

A VERY nice 77F at 5:53PM after briefly eclipsing 80F ( 81F ) for a couple hours this afternoon,  and ...some unexpected, Big drops and dusty breezes between 8-10AM as the tail end of the front i mentioned last night passed through AZ..  Generating Severe Weather galore across eastern CO. / N.M. and parts of N.W. KS. atm.

Another pleasantly cool night ahead, ..Then the warm up begins..

Quick check of how the snowpack in CA is looking ..Yes, there is still quite a bit left to melt.. Anticipate another big melt surge w/ the upcoming rise in temperatures.

My little corner of Florida finally cracked 90 yesterday for a couple hours before the sea breeze kicked in. Not for long but summer is here, even the sun looks harsher. Way different than the urban heat island in pinellas county where it was much hotter by now

Min of 50f/10c and a high of 59f/15c, which has been the lowest high so far in May. Every other day so far in May has been in the 60s or 70s which has still been below average. Luckily on Saturday the high is forecased to be 20c/68f and 23c/73f for Sunday. It looks like a blocking pattern will kick in next week. The forecast in London looks drier than many places in the Mediterranean. The rest of May is forecasted to be around average with a few below average days. There is uncertainty for the start of June but the long term forecast (at the moment) is predicting the end of June, July, August and September to be above average. It also looks like BC Canada are going to have way above average temperatures which will be for speeding palms up over there. Currently the sea temperatures are above average, in the south the sea temperature is the same as it is in San Francisco despite being 840 miles further north. Here are a few images showing the rainfall in Europe, the image of London's is the last.

Still not much has changed. Gloomy with lots of sun, warm temperatures but thunderstorms with heavy amounts of rain. ☀️⛈️ Yesterday's high was 25.5°C, like the other days. This morning (currently at 6:30 a.m.) is pretty cold compared to the ones before though. A low of 10.1°C which I think, is the lowest this month so far. Towards the middle of next week a short cold dip is predicted with highs below 20°C but also drier. After that temperatures are supposed to rise significantly with lots of sun and no rain. We will see! ... :greenthumb:

A warm 78F and slightly more humid evening as moisture from the east and southeast knocks on our door..

Recent 24 step Long Wave Infrared loop Via College of Dupage Sat. imagery.. Some decent -for May- thunderstorms over S.W. N.M atm as a surge of moisture marches west up I-10 toward Tucson and Phoenix. Can also see the Low over the Great Basin that is helping to draw moisture north and west from the Plains / Mexico.  There's also another low forming somewhere near the top of the Gulf of CA. ..which is also helping draw moisture west..

While the current Wx Underground outlook does not have any listed, other forecasts today are suggesting it is possible an isolated storm / shower or two may get pretty close to the area tomorrow ..and / or over the next few days.. We'll see.   If any rain falls, it will be light -at best.   Heaver showers/storms ( by May standards ) more likely for the mountains, S.E. AZ ..and maybe Tucson.

Heat hangs on, then backs off a little ..before heading up again later. Dew points hang in Monsoon-ish territory tonight - at least Friday.

Unusual " Similar to the Monsoon, ...but not the Monsoon "- like pattern may hang around ..perhaps take on a slightly more monsoon look ( moisture pooling over the Sierra Madre Occidental and being drawn north around a high over the Great Basin, if that occurs ) as we get closer to the end of the month. May also see the first stretch of 103-105+ heat arrive around the same time..

Watching for more moisture reaching into CA as well. ( Upper level low may try to form somewhere just west / slightly southwest of the Bay Area, luring more moisture west of the Sierra Nevada / Great Basin. ) Some models continue hinting at it, while others don't  ..or keep most of that moisture east of the Sierras / Northern mountains up near the CA. / Ore. border.

We'll see..

Min of 49f/9c with a max of 74f/23c with 40% humidity. The max UV was a 7. It was sunny around midday then for the rest of the day there was a thin layer of clouds so the sun wasn't as strong. It's currently 63.5c/17.5c at 10.30pm.  Here a photo of the sun shining through the clouds today 🌤️.

A toasty, but reasonable 99F atm. Dew points are up, but it and humidity atm are still on the dry side of " humid " ( 40deg / 19% )

We'll see if any of the current activity \just to the south / east makes it here before / just after Sunset.  On-going storm activity over the White Mountains to the N.E. of Phoenix / the Valley may send a dry ( ..and maybe slightly dusty ) gust front west / southwest across the lower elevations later ) Similar story, if not slightly moister Atmosphere tomorrow.

Max of 22.1C / 72F here yesterday. Temps will be slightly down on that today however, although warmer conditions are starting to push in properly now, finally.

Up to mid-May it has been the wettest and dullest spring on record for me here. Also the latest 18C on record and also the 2nd latest 20C and 21C on record. Only 1983 had a lower spring max temp at this point. 22.6C / 73F appears to be the highest max on an official Met station up to now. That is pretty poor for mid-May. As I said, only 1983 had a lower max at this stage.


There has been an obvious lack of warmth so far this year, although nights have been pretty mild. All that cloud cover and rain has just kept things very mild overall. No cold, no heat. Here are my spring rainfall statistics for the last 5-6 years. Clearly this spring is a massive outlier and unusually wet. The ENSO cycle transitioning to El Nino may be to blame as well as the SSW event in late Feb / early March. This spring has been 7 x wetter than recent years. A huge anomaly.

SPRING RAINFALL…

2018 - 0.97 inches

2019 - 0.91 inches

2020 - 0.86 inches

2021 - 1.24 inches

2022 - 0.89 inches

2023 - 7.21 inches

Med conditions will begin to lock in now as we enter summer, with the subtropical ridging Azores high pushing into southwest and southern England, as well as cold seas helping to block/dissipate any precipitation coming across from the continent. This usually happens around April-May and can last well into September. I fully expect the warm summer Med (Csb) transition to continue this year as well, similar to recent years. We may have had record spring rainfall this year, but I expect it to be very dry again from June - September now. A heat burst (25-30C) in 10 days time followed by the Azores high establishing ahead of summer. A similar setup proceeded summer 2018 which was another true Med summer for southern and central England.

As a new week starts, awoke to the strong < and uncommon, in May > smell of thick,  moist air wafting in through an open window from outside. Getting up, could see it had just stopped raining. Already close to 90 ( 87 ) at 8:11AM Dew Point hovering between 47-51deg. As is usual, some of that moisture will mix out as the day progresses..

As advertised, Mother's day ended up breezy, hot, ..'N dusty in the afternoon here.. BARELY missed out on a couple storms that tried to move into the valley. Tucson on the other hand, ended up w/ about .50" of rain in some spots, and some downed trees / power lines/ poles from frisky storms that blew through there..

"UofA's " Cloud Cam " captured yesterday's activity well down there.. Link to a full days worth of timelapse video, for anyone interested : http://www.atmo.arizona.edu/products/wximagery/movies/full_day.mp4   We'll see what flavor of " Cloud Candy " is captured today..

Similar story today for both areas..  While most of any activity which forms today should stay up in the mountains, 10-30-ish% chance we might see -something.. later.. More moisture in the atmosphere today vs. yesterday area-wide, but better odds of storms,  brief ..but wetting..  rains ( ..vs. Spit )  down south, as usual.  90% sure we'll see more " MAY-soon," ...as some local weather geeks have decided to name it...   dust later..  Hot, but caged in the 98-102F range.

I think you need to get a better rainfall measurement as there is no way springs have been that dry in southern England lol 2018 for example had way more then 24 millimetres

@Samuel Previous springs in recent years have been VERY dry. In fact my previous 5 April’s (excluding this one) have averaged just 0.2 inches of rainfall here. Obviously this spring breaks that cycle/trend, finally. The chart you showed for spring 2018 has marginally above average rainfall for my location, although spring rainfall in general is pretty low normally anyway, so that still wouldn’t amount for much. Perhaps my old rain gauge was faulty back in 2018, or I missed some of the heavier rain showers here. Either way slightly above average rainfall during what is a ‘dry’ season anyway isn’t going to amount to much. Spring 2018 was nowhere near as wet or dull as this one that we have had. Clearly it is flipping now though to warm/dry ahead of summer.

2018 is the best analog to go by for this year as it also featured a SSW event in late winter (just like this year) and also transitioned from La Niña to El Niño through spring-summer (also like this year). That was the last time we had a ‘wet’ spring in southern England as well and of course it gave way to a dry Med summer. I think I only racked up 1mm / 0.04 inches for June 2018 here. Some official Met stations recorded nothing for the whole month of that June. Early summer this year probably won’t be as dry as that, but we will notice the subtropical ridging from the Azores high and subsequent high pressure blocking pattern preventing rainfall. That is becoming a repeated theme nowadays in relation to summer rainfall suppression. It’s not guaranteed but highly likely.

Min of 52f/12c max of 62.6f/17c with 39% humidity. The max UV was a 7. It has been pretty sunny sunny so despite the -1c 850 hPa temps, the temperature wasn't too bad today. Theres no rainfall in the 14 day forecast. The Metoffice have said the chance for heatwaves in June, July, August and September is above average. Especially the end of August and early September. The forecast looks not great but not terrible either.

Do you record the UV yourself?

According to this website a UV of 7 in London is exceptional.

IMG_3606.jpeg

On a Davis UV sensor. The Metoffice were showing a UV index of 7 a few days ago for Sunday on the forecast. The weather online UV forecast is not accurate. The Metoffice one in general is fairly accurate however when the sun is at its strongest at 12.56, if the sky is clear the UV can go up 1 more. The Scilly isles had a UV index of 8 according to the Metoffice the other day. Today the max UV I recorded was a 6 the same as the Metoffice forecast. The highest UV in the UK today was in St Helier which was an 8. Our UV for the second half of May, June and July typically ranges from a UV index of 6-8 with maybe a 9 one day.

There isn't an official Metoffice one what shows the recording for London other than other people's wunderground stations however this is for Belfast which is obviously quite a bit further north than here. The lgfl weather station in London that records the UV index recorded a 6.4 today.

Min of 9c/49f max of 64.4f/18c with 40% humidity. The max dewpoint today was 44f/6.6c. The forecast for the end of May looks better.

Hot n' humid ..despite the actual humidity only sitting  at around 16% atm..   Dew point is at 46deg though..  wavering between 99-102F which is a deg. cooler than yesterday.  Only dropped to the upper 70s ..maybe 80 here overnight ( was already 87F at 7AM )

Phoenix ( ...At Sky Harbor ) broke their daily overnight low by 2 deg.  W/possible, extensive cloud cover, and higher humidity as any showers/ storms die out, could be quite toasty again tonight.

Never though i'd be saying this ..in May..  but could be an interesting evening ahead..  Our Monsoon ( " MAY-soon " ) tease might just get kicked up a notch to " Teetering on Monsoon-like storminess " later.  Actually had a quick, but legit. shower pop around 11:30 last night.

Compared to yesterday, Atmosphere over the lower deserts, and a wider area of the state is moister ( Pwats  = Precip'tble water content closing on 2 standard deviations above seasonal normals ) /  moisture flow ..from the southeast / south... is stronger, with a legit 4-corners High pressure center set up in an ideal spot to the north today ...In MAY.

You know this isn't your typical " rare spit in May " kind of set up when one of my trusted regional forecasters comes out of hibernation to post a few things concerning a weather setup that mirrors what we wait another month to see evolving.

C.A.P.E. = Convective Available Potential Energy  ...On the low end of what it can reach, but -any- convective potential is a very rare sight on weather maps this time of year here..

Radar screen on the left is for 7-8PM Local Time, Right, = 4-ish PM  today ** from the UofAz AZ Regional WRF Wx Model. ( 15Z Run ) Note the big blob of storminess aimed at Phoenix from the east for this evening ( left radar panel )

While any rain we might get -below the mountains < ...Cuz the whole thing could bust, hard, >  likely wouldn't approach the " well into monsoon season  intensity " level,  suggestions of ...as much as 0.10"  to ....maybe 0.20" ..in  Phoenix,  in  MAY,    is a bit of an eyebrow raiser.    More likely, Could see T-storm outflow send gust front - generated winds in the 35-50MPH range across the deserts as well   ..We'll see.  Again, while it looks ideal,  just as possible the whole forecast for the rest of the day / evening here crashes and burns.


Looking outside,  and COD visible satellite,  View is very late June-like, vs. headed toward the end of May out there w/ lots of building cumulus east and south of town, and a few crowning compact storms mixed in. Nice west / southwest progressing outflow boundary up in the mountains atm too.

A good start, but not a guarantee for anything else later..  Reality says this pattern won't hang around -consistently- from now thru late October, but boy would it be nice if the overall season shifted to starting a month earlier, every year.  One can dream..    We'll see what the evening brings..

...On a side note, some impressive thunderstorm activity in the Pac. N.W. as well, while they sizzle up there..

Quite a pleasant week ahead for Perth with some rain expected next week, we hope.

We are getting a similar pattern down here although cooler. The min was 5.1C this morning and it’s drying out. A bit of a worry as we head into the wettest time of the year. We’ve had a bit of drissling with a few heavy showers that last for about a minute over the weekend and on Monday but that’s it. The BOM is saying a warmer and drier winter which is great for palm growing. I think it will be an early spring this year, compared to our late spring summer just gone. Going for 21C today and sunny.

It does not seem very promising today, but it at least seems like Friday onward will be comfortable. Lets keep fingers crossed. Its also been SO DRY that I've had to water everything even on cool days.

But this week it will reach UV 6 in London according to the Metoffice

The Met Office has a UV rating of 7 for Monday in London. Just saying. Obviously it is cloud cover dependent as well, so it can vary quite a big throughout the day, or drop off quite a bit.

Do you record the UV yourself?

According to this website a UV of 7 in London is exceptional. 

IMG_3605.jpeg

A UV rating of 7 is pretty standard for London in late May/early June on a sunny day. It is hardly exceptional. Likewise a UV rating of 8 between mid-June to early-July is pretty standard as well on a sunny day. A UV rating of 9 however wold be exceptional, which London has experienced only a few times before around solstice. However places like the Isles of Scilly, Cornwall, Isle of Wight etc reach will reach UV level 9 multiple times in mid-late June. They will already be at UV level 8 in about a week from now (late May) and then level 9 UV from 10th - 30th June under clear skies.

Actually Cornwall and the Isles of Scilly are currently at UV 7 right now as I type this. That is with a fair bit of cloud cover as well, which says a lot about how strong it ca get there if we are in mid-May. It is also quite cool there in the southwest due to the breeze coming off the Atlantic. It is pretty similar to San Francisco there right now in terms of temperatures and conditions. Identical really. Their UV is a bit higher though as they are 14 degrees of latitude closer to the equator.

Jersey & Guernsey in the English Channel are already up to UV level 8 on Monday. I wouldn’t be surprised if the Isles of Scilly & Ventnor reach UV level 8 on Monday as well, in late May. Do not underestimate the UV levels along the south coast of England and the channel, despite being at 50N. They will be pushing level 9 in a few weeks time.

Hoping for a big heat spike to end the month as it is long overdue this spring. I will be watching the models closely and anticipating summer’s arrival…

80F/27C at noon on the way up to 90F/32C today with abundant sunshine.  NO rain forecasted as far as they can see out, and I missed out on the T-storm action the other day.  I saw the dark clouds moving around, but they tend to swing wide of my location.

Max of 22.8C / 73F on Thursday afternoon with quite a bit of sun.

Nights still generally cool under the clear skies. Days progressively warming and dry now as the Mediterranean conditions start to lock in and take over.

After the wettest March-April period on record and a relatively wet start to May, the water tap/faucet has almost been shut off completely again now, right on cue. No measurable rainfall for 6 days now and only 3mm / 0.1 inches over the past 2 weeks. A pretty sudden and rapid transition from the very mild/wet spring conditions to a warm/dry summer feel. Many places will be going into June with no rainfall for about 2-3 weeks based on the precipitation charts for the next 10 days.

I'm not sure what the hell is going on in the actual Mediterranean. Half a year's worth of rain in a day in parts of Italy - floods, landslides, hail, hurricane strength winds etc. The whole Med region has taken a right battering from Spain to Libya to Turkey. Everywhere has been soaked. The worst is still yet to come as well.

 

Cars submerged, 13 dead and 13,000 people evacuated in Italy with floodwaters reaching almost 2 meters in height in places. The main flooding event is yet to come still.

 

Meanwhile in the hottest city in Europe, Seville... extreme hail...

Min of 51f/10.5c with a max of 71.5f/22c in London today with 38% humidity. The max UV was a 6. The forecast looks ok especially when you factor in the lows will always be higher here than forecasted. Some of the gfs runs are showing 28c temps.

Beautiful sunny top of 26c today, a nice afternoon to shoot to the beach for a couple of hours after work.

What a week! ..But, as the saying goes: All good things must come to an end ..At least temporarily,  ~hopefully~   86-90 around town under gradually clearing skies ..and humid ( 53 deg / 31%.  Dew Point was flirting with 60 deg. earlier )

Regardless, While not amounting to much, a 4 day streak of wet-the-sidewalk rain ( more significant rainfall totals in other parts of town / up in the mountains ), Monsoon-level strength outflow wind events, some  lightning activity,  and Heart of Monsoon Season humidity / Dew Point levels are pretty much un-heard of  ..in May. 


One more opportunity for some activity in / around the valley this afternoon before the overall pattern shifts back to the more typical " blah " of May.. ...Hot n' dry down low, w/ a few storms roaming the high country / far east, and northern AZ  ..though, for the moment at least, heat in the low deserts looks to stay " reasonable "  ..We'll see how long that lasts, lol.

East Pacific is quiet as we enter the final stretch of the month and the start of Monsoon Season 2023 lurks on the horizon.. 

Some thoughts on that are already starting to trickle in but, as usual, still a couple week to go before i share mine ..and those others.   Until then, time to crank up the heat, and watch how everything starts to come together.. 

At least this year, the road between the end of " nice weather season, part #1 ( Spring ) ", and the start of the best season isn't as long and mind dulling as it usually is..

A cold 1.7C this morning just before sun up. Right out in the open the grass was starting to go a bit crunchy, but anything closer to canopy wasn’t crunchy. Still it’s a bit cold for this time of year. That’s more of a June July thing. Going for a top of around 20C and blue cloudless skies. 
 

The reason for the cold mornings and bright blue sky days is that the high pressure ridge is sitting a bit too far south. This is due to a strongly positive SAM (southern annular mode) which measures how close the cold fronts and westerly winds stick to Antarctica. A positive SAM sees them closer to Antarctica and this year it’s been a record positive one. So cold fronts and westerly winds are missing at the moment. So it’s dry and clear and still. Normally we are getting strong westerlies that break small branches and new shoots on my bamboo groves, but not this year. Hopefully we will get more cloud cover and westerlies as we approach the southern winter solstice or we could be in trouble.
