Showing less and less of a closed upper level low on models with the main piece, pushes the front through and that leftover energy is interesting to watch. Unfortunately don't see much coming of it though but will continue to watch for some signs of fun. 

Might help me get a little front end flakes, I'm expecting to be back to zero after the system passes though.

 It's not the best CAD setup for my area, but there's still gonna be some.  Not expecting major changes at the this point, but perhaps sampling with the 12z suite throws in a wrinkle.

It will be interesting if we can get enough spacing in between the pieces of energy. Not going to trend to a big storm but could give some folks in SNE and maine some fun. May even have some snow showers back this way with the upper level low close by.

It’s quite possible that many locations in the NE could go without snow for the entire month of January.  Could def set some records here.  

Ensembles showing a pattern change around the 21st or so....time will tell if it leads to any storms though and if it has any staying power or ends up just being a blip in the season.

Well there’s definitely going to be a more favorable more pac jet as we start to see the - to neutral pna breakdown to a positive pna around that timeframe.

NWS Caribou issued a Winter Weather Watch which means their belief is that there is a 50% chance of at least 8" of snow (based on the new experimental guidelines for my forecast area).

I like the optimism!

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
High pressure will exit across the Maritimes early Thursday.
Low pressure lifting toward the eastern Great Lakes will draw a
warm front north toward the region later Thursday. Expect mostly
cloudy skies early Thursday, with snow then expanding eastward
across the region during the afternoon in advance of the warm
front. The low will track from the eastern Great Lakes to
western New England Thursday night. Precipitation will expand
across the entire region with increasing intensity Thursday
night. The low will draw warmer air north. Based on critical
thickness values, expect precipitation will remain mostly in the
form of snow across northern areas Thursday night though could
begin to mix with sleet or freezing rain late. Across central
areas, expect snow to transition to a wintry mix. Across
Downeast areas, expect snow to transition to a wintry mix, then
to mostly rain. The low will track across the region Friday
through Friday night, though the exact track and timing are
still uncertain. Warmer air moving north will keep precipitation
in the form of rain Downeast Friday. An early wintry mix will
transition to rain across central areas. Across northern areas,
expect snow will transition to a wintry mix then to rain/snow.
Precipitation types across northern areas will be dependent on
the eventual track of the low and how much warm air is drawn
north. Gusty winds regionwide Thursday night into Friday, with
gusts up to around 40 mph possible along the Downeast coast.
Rain, or a snow/rain mix, will eventually transition back to
snow across northern/central areas later Friday night with
colder being drawn south. Across Downeast areas, rain will
transition to a rain/snow mix late. Total snow accumulations
Thursday afternoon through Friday night will be dependent on how
long snow can persist Friday, along with how rapidly the
transition back to snow occurs Friday night. Both factors will
be dependent on the eventual track/timing of the low. Slightly
above normal level temperatures Thursday, temperatures then
warm through Thursday night. Temperatures will be at much above
normal levels Friday.
