2-18 Hudson Valley, CT, MA, RI special

Results

2-18  1-3" in Albany area including Litchfield.  2-4 rest of N CT and RI.  3-5" in MA
Radar image shows basically what happened. Precip split N and S of us.  We did get some showery type of snow later and some sleet mixed in over night.


2-17
Been watching the 2/18 and 2/10 period for a week now.  Two systems, both weak and not much to be excited about.  The first will come through tonite.  For areas north of the Merritt I think should remain mostly snow and 2-4".  From I 80 south, ice/rain.  In between 1-3" snow with some mix. 

The 12z model runs were fairly diverse with the ICON having 1" and the RGEM having 6".

Euro is right in the middle.  GFS is lighter and warmer.

GFS
Should note the GFS map may include sleet and ice, so it really should look like the Pivotal map
NWS has a winter weather advisory out for the northern suburbs.
After the heavier stuff falls overnight, Monday should be dreary with either some light snow, freezing mist or rain.   Nothing to accumulate unless you're further east in RI/MA

The 18z Nam threw out some pretty impressive precip for some reason.  Could be that it sees the -8c line as collapsing in some heavier precip and during the upward motion at 10,000 feet.

That resulted in this snow map, which is less likely, but still possible.  This type of snow would required a winter storm warning.  18z GFS came in a bit heavier too, though more along the CT/MA line
So look for 1-2" in NNJ, LI, CT coast.  2-4" from the Merritt to I84 (with some potential for 6") and 3-5" for 84 to the MA/VT/NH line (with some potential for 8")

Storm 3 - could be the one! (spoiler, it was)

 2/9  Set up is an upper low over TX that heads northeast into TN valley and then transfers off the coast. At the upper levels, there's ...
