didn't ask me but agreed ( bold )

it's marginal+ environment, but so far there are ptype rad returns west of the capital district, already, prior to best dynamics and also, albeit fractional ... it's a colder leaning quagmire during the night at this time of year. 

John, assume you are always included! Lol..  thanks for the thoughts...

This is a favorable setup for snowfall, even down to the Mason-Dixon line. If it was late Dec instead of late Nov, I would be more open to workable coastal snowfall, though that is a difficult ask given how warm waters are. The main points of contention are: 1) how quickly does the vort get ejected? 2) how much of the vort gets ejected? and 3) how strong is the confluence? I would argue that the confluence is the most important part of the setup... if it vanishes, there is not enough press from the cold air and the setup is DOA. However, if the vort comes out too early, it won't matter. This is unlikely, though... if anything, the vort would come out of the Rockies too late or too sheared rather than before confluence forms. How the 50/50 ULL trends is crucial to this setup and I will be watching that closely.

 

 

Is there a baseline ocean temperature "required" for consistent snow on the coast?  Or, a gradient where it's more likely at or below a certain water temp?

.07" of rain on the day so far.  Forecast was for between 1.25" - 1.50"ish but it's still early yet.

How you feeling about the far eastern NY / Western CT high terrain areas during the predawn hours Friday?  Crazy model discrepancies?  Erring on the low side of the model consensus, but kinda has now-cast type of feel to it?  

 

Yeah it’s one of those scenarios where if you can rip the column with massive omega, there could be a few hours of a surprise heavy wet snow. Column needs to cool a decent amount but we know huge dynamics can do it if they pan out.

18z HRRR rips in SW CT later tonight

Is there a HRRR/GFS rule? Just kinding, but they are pretty similar in trying to flip Fairfield County over to heavy snow. Another case where the hill behind me might pick up a couple inches and I have white rain....should be fun to watch it develop, if it does

Yeah, I'll be pouring a cold rain, and 15 miles to my southwest they'll be buried in 10 inches.
