IsentropicLift Posted January 21, 2013 Author Share Posted January 21, 2013 29/15 Hope this event doesn't become pure virga like the last event. The dewpoints are very low, so it's probably going to take a pretty good burst to get snow to the surface. Link to comment Share on other sites More sharing options...

TWCCraig Posted January 21, 2013 Share Posted January 21, 2013 12z NAM giving 0.1" of precip from Nassau/Suffolk border out east. Looking at 12z NAM reflectivity, we get about 4 hours of light snow, then a 1 hour break, then a quick burst at the end. Link to comment Share on other sites More sharing options...

Looking at 12z NAM reflectivity, we get about 4 hours of light snow, then a 1 hour break, then a quick burst at the end. The way the radar looks and with how dry the high res models are looking it wouldn't surprise me if we all wound up with nothing. Link to comment Share on other sites More sharing options...

IsentropicLift Posted January 21, 2013 Author Share Posted January 21, 2013 The radar out of State College is picking up some. I supposed that it's still possible that we slightly over perform. Link to comment Share on other sites More sharing options...

PB GFI Posted January 21, 2013 Share Posted January 21, 2013 I think the models are little more moist , and if you see the radar start to fill in later I think UPTON will issue WWA for 1- 2 inches accross Long Island for this evening . Mt Holly goin with 1- 2 accross I- 78 - thats put the Island in those corsshairs . Link to comment Share on other sites More sharing options...

SnowGoose69 Posted January 21, 2013 Share Posted January 21, 2013 00-04Z is probably the window to watch for most of the area minus eastern parts which will go later...a band of snow will likely rotate across in that period, just a question of how much...the 12Z SPC WRF continues to show a narrow band crossing 01-03Z.

History tends to repeat itself so we may do that again some day. Out here we've been experimenting with issuing winter weather advisories for events like this.

Nikolai Posted January 21, 2013 Share Posted January 21, 2013 Judging radar, I feel like this is the first event this winter that could potentially give NYC an inch or two... not bad! Link to comment Share on other sites More sharing options...
