The first freeze of the season is already imminent for much of northwest Europe. A new phase of -NAO (North Atlantic oscillation) and high pressure over the arctic (northern blocking) means that cold arctic air is channeled straight down from Greenland and the high arctic into northwest Europe and Scandinavia. Autumn has been very mild up until now for all of us in northwest Europe, with record high maxes and minimums in many places, but all that is about to change, at least temporarily with the arrival of this arctic blast on Monday/Tuesday. It is looking like quite a significant cold snap for mid-November in some places like Iceland, Norway and Ireland in particula…

GENcast AI weather model
by flplantguy- 3 replies
- 547 views
Has anyone heard about this new AI generated weather model? Im seeing commentary articles about it being pretty accurate to 15 days. They provide the source code at github also under google-deepmind/graphcast. If anyone here is savvy enough with it, you can download the ERA5 dataset and run it yourself apparently. They want it available to anyone so everyone can benefit apparently, but i do not have the know-how to do all of that myself yet (im going to try to learn more though). What are people's thoughts? The accuracy of the data sets on a microclimate level is still poor, so it wont change much for me personally based on the PRISM map data.

Microclimates in Backyard!
by CascadiaPalms- 2 replies
- 210 views
Does anyone have these, can you describe? I was stunned by the "difference" in temperature by putting three different weather sensors in my backyard. Long story short, my property is 0.25 acres, yard is roughly half of that. This could really make a difference in regards to a palm needing certain warmth/cool. The three sensors would typically read like this. These would be the max temperatures of the day. Local temperature on weather app : 83 F Sensor 1 (In the shade entire day, surrounded by trees): 75 F Sensor 2 (on back patio concrete, six feet off the ground in shade behind pole): 95 F Sensor 3 (Inside the yard shed on the wall, bu…

Some interesting Hardiness zone research

I was doing some web browsing and found an interesting page showing how much hardiness zones have shifted. I'm not sure if this has been posted here before, but I thought it was quite interesting. Closest city to me is Albuquerque, and it lines up with what I've noticed anecdotally. Overview of the research. https://www.climatecentral.org/climate-matters/shifting-planting-zones-2023 See the graphs showing the changes https://www.climatecentral.org/graphic/shifting-planting-zones-2023?graphicSet=Local+Shifting+Planting+Zones&location=Anniston&lang=en

florida Florida Freeze and Weather Station Data 1 2
by kinzyjr- 1 follower
- 45 replies
- 5.5k views
NOAA makes weather records from the Florida stations available to download for free. Out of the 1,700+ stations, 358 contain at least some temperature data. If one were to download all of these records, import them into a database, and use some crafty SQL queries to generate sheets for each of the impact freezes it would provide a really good side-by-side resource to compare the microclimates in each region of Florida. That is exactly what has been done with the 0000_202011040720_F_SQL_v2.xlsx spreadsheet attached to this post. Each tab in the spreadsheet contains records for one of our unfortunate cold events. The records come sorted first by the TAG column, whi…

I thought it was time for Texas to have a new hardiness zone map, so I made one myself. Data is from 1992-2021 NOAA minimums. *Not completely accurate, but I hope you like it and maybe consider using it (thank you) in the future.

Tampa, FL vs Brownsville, TX Long-Term
by ahosey01- 8 replies
- 396 views
Was doing a little research and thought it would be interesting to compare Tampa, FL to Brownsville, TX by decade in terms of absolute minimums, since this generally determines the kind of palms we can grow. What I found surprised me - in the years for which data for both Brownsville Airport and Tampa Airport exist, Brownsville averages 1.39F warmer in terms of absolute minimums in any given year. The 1960s were a fairly even split, with Tampa being warmer the first half of the decade and Brownsville being warmer the second half: Tampa Brownsville Comparison Year Minimum 20-Year A…

Weather since 2021 in South Texas
by Victor likes palms- 6 replies
- 3k views
Ive been studying highs, lows, and rainfall in Beeville Texas and I’ve noticed that every year after 2021 has been poor for plant growth. 2021 brought above average rain but every year after has only had precipitation in the low 20s and even only 18 inches while the average is 32 inches in Beeville Texas. Pretty much every winter after 2021 was harsh and we even saw 17 at the start of the year; what could be the reason for such poor weather. Have any of yall also observed poor weather since?

I have noticed on the USDA Hardiness Zone Map, some tiny patches of zone 7a started popping up a long the west coast covers most of the Manutou Islands of Michigan, but when you look at the downloadable map, it doesn't show that 7a exists- I know 7a doesn't change anything about the climate at all, but it's just interesting to see a new zone leaking into Michiga

Monsoon 2024, Part #3: Some Final numbers, what happened this year, ..and some final thoughts...
by Silas_Sancona- 1 reply
- 317 views
After lots of delay, time to play catch up and round out this year's Monsoon Season thread here in the Southwest.. As mentioned, while not quite as awful as last year, 2024 was still pretty bad in many areas, esp. locally. That said, Tucson ..and a few spots down south ..and north of PHX managed to pull of a ..decent.. season. While such variability is a fairly typical mood of the Monsoon here, it was quite pronounced this year. At the other end of the spectrum, while the northern / northwestern states generally fared poorly, it appears central and Southern Mexico erased some of their drought this summer.. At least according to the Sept. 15th upda…

Worst start to a summer in 20 years for the UK 1 2

So the temperatures have been crap here really since June 1st. We had a 24C / 75F day on the 2nd June but the rest of the days have been pretty lacklustre. Not very warm, not overly sunny but still pretty damn dry. Still only 0.2mm at Heathrow in London. Data for St Catherine’s Point near Ventnor on the Isle of Wight. Really poor daytime highs there, but bone dry. Data for Culdrose in Cornwall near Penzance. Some warmer days than Ventnor. The airmass overhead is derived from the arctic and very cold for the time of year. Much of the cold air has been shunted out of that arctic region and sent in our direction. More and more of it…

Climate Voyger: ..Plant zones of the future????

...Anyone play around w/ this?? Thoughts?? Regardless of how accurate the " possibilities " might -or might not- be, kind of interesting seeing how much the zones could shift over such a relatively short amount of time, esp. on this side of the U.S. Maps have a similar look / feel to the data used by PRISM, Imo. AZ: ..Note that in past casual discussions regarding how warm things might get around here, i'd mentioned how ..i myself.. could see Phoenix reaching into 11A, while Tucson reaches zone 10 ..and the far southern end of the state could jump from zone 8 ( A and B ) to solid 9 ..with pockets of 10 south of Tucson in numerous places i've exp…

Well, it’s time for a new thread. Calendar spring is here now and it also appears that the real spring is too. Yesterday on Sep 1 we had a 24C day then some small rumblings and a thunderstorm which dropped about 5mm of rain. We are now at the point in time where the weather is gradually on the improve and the weeds are growing like mental. Hopefully a great growing season awaits and the palms flourish.

General 2023 USDA Plant Hardiness Zone Map Discussion 1 2

Jumping off the FL-specific thread, I figured I'd start a general discussion on the release of the latest map by the USDA: https://planthardiness.ars.usda.gov/ Kicking things off, a few interesting things I've found: Inclusion of a significant amount of 10a throughout SE Louisiana including a small section in DT New Orleans along with a *very* small amount of 10b Northernmost extent of 10a extends into SW Oregon (Brookings) Poor representation of cold sinks in microclimates throughout the Rockies: Jefferson, CO hit -24f a couple of weeks ago during a fairly typical October cold snap, but they're listed at 5a (-20f to -15f) and will routinely fall …

Its not winter yet, thankfully, but the cold fronts have started. There have been cold fronts periodically, but you could never tell a difference from them, that is until the week before last week. A cold front came through and knocked morning temps into the low 60's, highs remained the upper 80's though. Looking ahead into this week, another cold front is forecast to sink south across the eastern US. Morning temps here are currently forecast to be in the upper 50's toward the end of this week, highs in the upper 70's to low 80's. If this comes to pass, it would be the first noticeable cold front of the season

Hurricane Ernesto visits Puerto Rico

So much rain in 12 hours that my 11 inch volume rain gauge overflowed long before Ernesto retreated. Muddy river from the street above poured down part of my long driveway but no dramatic landslides near me thankfully. Awaiting assistance to try to right some now nearly horizontal palms and a bunch of other ornamental/fruit trees. I won’t miss two tropical almonds that broke and fell on each other. Lots of chainsaw work awaits, but my trusty sawzall and I cleared a passageway to reach my gate. Note the big Roystonea borinquena unscathed. I got city water back this morning. Still waiting for electric…
