How much heat have we used since Mid October this year? The most in over 2 decades in Hartford.


Average Temp of 43.3° is the coldest since 2002 for the period. I used 1/2 cord of wood already! Incredible.

** STRANGE ALERT **.

3:10-7:10 radar loop.

Was supposed to rain here yesterday and today and doesn't seem like it will. Feels strange not to have rain easily falling. lol

You mean over PA? That is the Arctic Front coming but all that moisture will dry up before getting to us. Maybe a stray flurry or snow showers with it tomorrow

Yes this weather is lovely. But I prefer sunny deep blue sky high 75 low 53 for 5 consecutive days. Wait when did we get that weather? Was it in August or September this year? Or did we never get that?

It does appear there’s a fascinating 2018 Eastern USA pattern.

Colder late fall/spring and hot/muggier summers. Quick transitions from hot season to cold season. Not only was this true for us, but look at Central Texas that skipped from 99 degree highs to 41 degree highs very quickly.

As the sun’s most direct rays have moved deeper south of the equator, places to the South and west of us are getting a replay of our September/October

Florida is muggy and warm, and then somewhere over the Carolinas to mid-Atlantic it just plunges. Isotherms being close together (temperature change over shorter travel distance north-south) is common in years where there’s lots of moisture. A drive south along I-95 is like a timetravel drive from November to September.

Dryer locations and years lead to wider undisturbed airmasses. Mid-May is a time when it can be cooler in Florida than Minnesota and usually an example of the opposite of the current pattern and this has to do with oceans are cooler in May relative to Land so moisture is less pronounced.

This is also why Mount Washington New Hampshire in generally moist New England is above treeline at only 5,000 feet, while dryer Utah gets greenery well above 8,000 feet. Over the dry Andes Mountain range in South America, 17,000 feet high is still with trees.

Wow on the incoming cold.


Wednesday night and Thanksgiving...

All the guidance continues to advertise an extremely anomalous
bitterly cold airmass for this time of year...Wednesday night into
Thanksgiving. In fact...both the GEFS/NAEFS show the extreme nature
of this bitter cold falling outside the CFSR climatology in terms of
850 mb temperatures. Basically that means that these models have
never forecasted an airmass that cold at 850 mb based on reanalysis.

What the Heck! Here's the rest of it. Ocean Effect Snows!

An arctic cold front will be crossing the region late Wednesday
afternoon and evening.

Wednesday night and Thanksgiving...

All the guidance continues to advertise an extremely anomalous
bitterly cold airmass for this time of year...Wednesday night into
Thanksgiving. In fact...both the GEFS/NAEFS show the extreme nature
of this bitter cold falling outside the CFSR climatology in terms of
850 mb temperatures. Basically that means that these models have
never forecasted an airmass that cold at 850 mb based on reanalysis.

850T are expected to fall to between -20C and -24C...which will
result in bitterly cold temperatures. Low temperatures should
plunge into the single digits across portions of the interior with
lower to middle teens on the coastal plain.


Highs on Thanksgiving will remain in the middle to upper teens across
portions of the interior high terrain to between 20 and 25 on the coastal plain.
This will be accompanied by northwest wind gusts of 30 to 40 mph
resulting in bitter cold wind chills of 0 to 10 below zero
Thanksgiving morning for much of the region!

While dry weather is expected for Thanksgiving for the vast majority
of the region...some ocean effect snow showers are likely for the
mid and outer-Cape into Thanksgiving night. While there is some low
level dry air which will be a limiting factor...the 850 to SST
differential is extreme with a greater than 30C differential!
Certainly the potential for one half to two inches of snow in this
region...given the extreme nature of this airmass especially as
winds begin to turn more NNW.

How the airmass will look Thanksgiving morning. From the Arctic to the Northeast.
