Yesterday I said "last day of November". HAHAHA. I thought was February with 28 days. LOL


Beautiful day here today. Blue skies with some clouds now and then. Walked across parking lot in Short sleeves, someone just had to sarcastically comment "must be warm outside". Yes, it is. 42°F.

We had a cold snap in October with a low of 35F and they didn't issue a frost advisory for that. I would generally expect an area of frost advisories to be in the few counties south of the freeze warnings, because those areas would probably have lows in the 33-36F range. Yet I didn't see that in Texas when they had their cold snap a couple weeks ago.

It depends on the WFO. I never got a frost advisory, freeze warning, or hard freeze warning. I think since the first freeze was later than the average date, they didn't issue a warning.

Jacksonville was colder than NYC (or Long Island) this morning. weirdly, 850 hPa show the Northeast much colder than the south



maybe being on the east side of the airmass there was mild air at the surface? Usually, if the south is as cold as us they're under a cold airmass. surface temperatures from the same time:



Yea, Jacksonville had a strong inversion: 1.0°C at the surface, warmed up going higher, 850 mb was 8.4°C. NYC was more normal, 3.4°C at the surface cooler above, -4.3°C

Atmospheric Soundings

really strong radiational cooling? some cold air from previous days trapped? Good example of when the surface and 850 mb are doing something completely different.

Watch next weekend time frame(Dec 8-9) for a potentially interesting winter storm in the East

Did you see this post from the CT weather thread? No time to look into why.

November 2018:



7 day temp departures each week this month (minus 28th,29th) .

Each week been below normal in Eastern U.S except the 1st week for Northeast. Florida on its own.

The Plains must have some deep negative Avg departures for the month?


Which week was your favorite?

Jacksonville's low this morning was 38 F, not 34 F.

But yeah, they definitely ended up a lot colder than forecast this morning. My low was also 38 F, but that was right on forecast target.

Sunday could be 80 F across much of the south Atlantic, so big warmup.

wet week in downstate NY; two heavy rainstorms led to almost 3 inches of rain in a week; very muddy ground

Gorgeous 67 right now! 70s soon... then next week way below average again...
