We also have watches now out....for all of you who didnt predict this or lived through a flood up north here....its not any fun at all. First we get 30-40" snow on the ground, then warmth into the 40s and 50s (1996 was devastating) into the 60s and then a few inches of rain spells disaster for rivers downstream here. Ice jams and bends in tributaries are at great risk...I will watch my state and locales for updates and make a thread if need be on this upcoming dangerous situation. Stay Tuned.

I saw the potential days out ... and posted on this...the low is continued to be progged to still go west of the region ... thus rain/warmer air.
However, there's one thing that I think will have a chance to save you from devastating flooding this go-around ... [but still 6 hours of heavy precip (of up to 2" of liquid still isn't good for dense snowpack)].
THE DRYSLOT ... I'm seeing the best forcing/RH/Lift occurring ahead of the warm front ... as the warm front blasts northward, I believe this will shut down the heavy precip rather quickly (drizzle/light rain) ... followed by the cold front passage.
As the low continues pulling into NY, wrap-around snows should then occur ...
Confidence was higher in the forecast yesterday ... medium today ...
Stay vigilant and keep us informed Rob ... here's to hopefully that DRYSLOT!...
