Nothing really improved this run in terms of trough orientation, it's just that the jet dynamics were a bit stronger and so the precip field was more expansive and a bit more tucked in. The 18z run could very well switch back. I wouldn't even pay attention to it unless we see major changes from the GFS and Euro. Expand 1 down 1 to go.

jm1220 Posted December 7, 2017 Share Posted December 7, 2017 The northern stream acting as a kicker is right, it’ll limit how far NW this can get. But hopefully many of us can still salvage something. Link to comment Share on other sites More sharing options...

NJwx85 Posted December 7, 2017 Share Posted December 7, 2017 The GFS ticked slightly West, that was almost to be expected. That's why I was willing to go up to 2" for Eastern LI. Again, I said there could be snow, especially on LI. I expect mostly sunny conditions West of the Hudson river with some high cirrus. Link to comment Share on other sites More sharing options...

donsutherland1 Posted December 7, 2017 Share Posted December 7, 2017 On 12/7/2017 at 3:46 PM, Snow88 said: People give up way too fast Expand The tendency to write off potential events seems stronger this year than in recent years. Just sticking with probabilistic scenarios, my thinking from a few days ago that Friday-Saturday could bring parts of the region its first measurable snow event (a light accumulation) seems to have held up reasonably well. The pattern has a higher than climatological frequency of measurable snow events (1950-2016) for the relevant timeframe. The event around the 13th could be a bit larger. None of these are guaranteed outcomes, but I like how things are evolving. if there is to be a KU-type event or a significant snowfall (widespread 6” or more amounts), I suspect that the second half of the month would be more favorable.

Expand I don't disagree with the last part but you have to acknowledge the improvements at 500 out of the N branch These are usually poorly sampled in the mid range and can make or break a forecast.
