Way worse last night than the night before...31 degrees here at 5 a.m. Lots of 25s and 26s down in the valleys (Walnut Creek, Pleasant Hill). The duration has been bad as well...it was in the low 30s by midnight. The night before we barely touched 32 for less than an hour. Forecasts got this one wrong.

sorry to hear that Ben. my low was exactly the same as the night before-35. No wind at all...

It's significantly colder than yesterday. We barely touched freezing yesterday. At 7 a.m. this morning, most of the East Bay that does not have elevation is in the mid-20s.

29 f. here again this morning. There is a lot of frost everywhere now, yesterday only roofs had frost. My C. macrocarpa's oldest leaf was fried yesterday. Also my Ficus dameropsis lost about dozen leaves do to wind, half of it's emerging leaves were melting do to the cold!

that sucks. Ficus Dammaropsis is such an expensive plant and of course great looking.

It is interesting as it was actually warmer by 2 degrees last night vs Wednesday, 35F vs 33F. There is a bit more frost on the cars, but only the exposed surface, one car is slightly canopied by a butia frond and where covered the water is just dew. 42F on the porch.

it hit 39 at my Carlsbad house this morning.

I know my vista property got hosed again this morning. Yesterday day it was 28F at the bottom of the property and 33-32 everywhere else at the tops of the property with lots of frost in the open areas with no frost under canopy. I'm guessing its the same today?

Almost identical to yesterday, 37 in front yard, 39-40 in the back. It held cold longer into morning though, due to no wind at all. Still, doesn't look bad here, but I'm so sorry for folks who are getting the real cold stuff...

I agree the forecasters were way off. they were calling for 35 F in vista yesterday and I had readings at 28F & 29F at the low parts of the property and 30-31.5 at the higher parts of my property with lots of frost in exposed areas. Not to mention the ground was frozen in may places

Let's hope they are right about the forecasted warm-up starting today.

Same as Carl for me, 33.4 yesterday and 35.5 today. No frost. As soon as the wind came up to 3 mph I jumped 10 degrees, at 44 now.

In the coastal canyons, it seems a bit worse today. 30F in my 'hood. I left for work when it was still dark, but I suspect I'll see some damage when I get home. In my area I've learned to take the San Diego forecast, then subtract 5-6 degrees. Lovely in the warmth of summer; lousy at this time of year.

36f on the warm side of the house. Still as the grave.

Cold side of the house there is frost all over the grass. More so than yesterday. Palms and other plants appear frost free.

On the bright side, I was able to see how the cool air flows through my property thanks to the frost patterns. Hopefully I can use this to my advantage down the road.

Unless the dew points make some dramatic increase today, I think there cloud be a repeat +1 or 2 degrees. So tired of winter :(

I need to understand how this dew point stuff works/influences temperature.

NOAA said that I would get to 33 which I thought would be around 30-31. It just got worse because of my elevation. My next house will be on top of a hill... Top of the hill here was 35

37f again this morning with more frost then the prior night.

No frost down on the grass.

I have a large gigas that hangs over part of my roof and can see what an advantage having a canopy makes. No frost on that part of the roof.

Bananas and heliconia spared as it got down to 34F here. No damage to anything but most of my forecast sources had called for 37 to 40F. Let's hope they're right about moderating temperatures starting today. A big warmup is forecast in the next few days with low 70s next week. It can't come too soon!

On a normal night with no wind, you can usually expect the temp to drop 1 or 2 degrees below the dew point temp taken from 5pm. I was at around 33F so figured to get around 31. This mornings dip brought some cooler air in and made the night a disaster. The dip is change in pressure from the sun that hasn't risen yet. Pretty cool stuff, google it

Interesting, Jim - it looks like they really got it wrong across the Bay Area. Very disappointing. I just hope tonight holds for the high-30s; my confidence in the forecasts is definitely shaken.

Ben,

FYI....

Dew point - The temperature at which the air temperature must be cooled for water vapor to condense, forming water droplets, fog, or clouds.

I don't know if that will help you or not.

Thanks John...I was finding that, but what I was interested in is the relationship to ultimate lows (not finding that.) Enigma's explanation is interesting and I will be monitoring that going forward.

The high yesterday was 15 degrees warmer than the previous day, but the low this morning was 2.7 degrees colder. Clear and dead calm last night. 32.1F at 8:30PM, 30.3F at 10:30PM, 25.7F at sunrise. Bring on the rain.

Definitely wrong on the forecast.

Numbers don't look right now, things could change but I think an exact repeat is possible at this point

looking at the hour by hour forecast , a high of 59 for me today with a low of 38 for Friday night. But, also forecasting a paltry 2mph wind overnight. Oh, how I wish I could hear my wind chimes again....

I was 3 degrees warmer this morning with a low of 40f. It was breezy all night, so much so that it blew off all my sheets. At the bottom of my hill it was 32 with light frost on everything from roofs to grass.

I'm sure glad to see things starting to warm up in the day or two. I never want to see frost again!!!!!!!!!!!!!!!!!!!!
