Emergency alert on my phone. Glad they do this because people are clueless and never look at the radar or weather forecasts

That was nuts!! 32mph gust and blizzard conditions. Roads only wet but visibility was below 1/8th of a mile! Whiteout! Winter Wonderland again


I hope you all experienced it and are safe. Not too common CT see these, especially near the coast

My weather station showing the snow squall dropped the temp from 37° to 28° within 15 minutes and came with a peak wind gust of 32mph. Multiple gusts over 15mph

Interesting and Interesting

The Thursday-Friday timeframe is looking more and more
interesting as confidence is increasing in winter weather
returning to the region. Surface low pressure develops across
the mid south, and heads through the OH Valley ahead of the
aforementioned upper trough. Models are coming into a bit better
agreement--for Day 6 at least--that a secondary coastal low
will form by early Friday near DelMarVa and work up the east
coast. At this point, track and intensity uncertainty plays into
the ptype uncertainty and changes to this scenario are likely,
and expected, over the next few days.

Global models have trended colder, with the GFS and GEFS on the
colder side, and the EU/ECENS on the (slightly) warmer side.
Thus, the NBMv4.1 ends up somewhere in the middle, though is
showing about a 20-30% of >6" across the far interior, with
5-20% across the remainder of the CWA, which is noteworthy. For
now, have kept a rain to snow to rain trend across NYC and
coastal locations, with a mainly snow event across the interior.
It should be noted, however, that the setup with cold high
pressure to the north nosing into the area--a cold air damming
signature--does seem favorable for at least for some ice/mixed
precip across at the onset early on Friday, especially north and
west of NYC. This is supported by model soundings as well,
depicting a small warm nose in the 700-850mb layer. Nonetheless,
given that it`s so far out, have maintained a R/S mix in the
forecast for this time. Stay tuned.

High pressure then builds in from the west for the remainder of
the long term, with below normal temperatures anticipated.

Area Forecast Discussion
National Weather Service New York NY
636 PM EST Sun Feb 20 2022

The models have trended north for Thu and Fri. Most of the pcpn
however should be on the front end with the dry slot pushing thru.
So, with a 1040 high over QC, it is expected there will be some
accumulating snow before a changeover to a wintry mix and/or rain.
Best guess now would be 4-8 far nrn tier, 3-6 down to the CT coast and into nern NJ, and 2-4/1-3 NYC and LI. The pcpn could start as
some lgt rain or sleet Thu aftn/eve before the column cools.

Well this is getting interesting. I am all for one last blast of winter, then moving on to a nice warmup in March.

North trends = snow to mix for everyone.

Lots of liquid 1/2-1". If trends south we could be looking at a 6-10" snowstorm.

Otherwise probably a 3-5" before changeover. Less at coast

Euro data for Danbury...Look at that one moment in time the 850mb (5000') layer goes above freezing. UGH!!!!!!!!!!!!!!!!!!!!!!!! But the surface is still below freezing...barely.


Depending on how thick the below freezing air is under 5000' will determine if its sleet or ice falling. OR if the above freezing layer is thick enough it will be a cold rain.


UGH!!!!!!!!!!!!!!!




Initial storm going too far north west of us! Coastal storm too close!!! If that initial storm transfers to coastal south of Philly this would of been all snow. A lot of it.

Do these 2 offices not talk to eachother?? NWS Boston has 3-4" for Fairfield while Upton has 2-3".


I mean its only an inch but if you're going to add a location not in your coverage area why not coordinate with the office?
