Good morning all!
Snow is on the way tomorrow and this is the start of some frigis air this week for the entire Midwest and East Coast. The models are doing a decent job tracking a pesky Alberta Clipper now moving through the Midwest. Snow totals are up to 5" in the Midwest but the little snow storm will lose some of its punch once hitting the mtns of PA/NY/WV/MD. Here is what the models are saying right now.
THE NAM MODEL
Philly 1.0" to 1.5" area shows .10" liquid off a 15:1 ratio
Allentown 1.0" to 1.6" and the Lehigh Valley is about the same with .10" of liquid 18:1 ratio.
Baltimore 1-2" shows a bit more on the NAM with .20". Temps are a wee bit warmer but they have a little more liquid to work with for Northern Maryland.
DC area 1-2" of snow off a .16" of liquid to work with Tuesday.
NYC Area .5" to 1.0" is further north of the main storm track so the amounts are lower
South Jersey .7" to 1.2" temps are little warmer and precip just a little less.
The wildcard could be the possible moisture throw back off the Atlantic, we'll know that by mid morning tomorrow. It could bring just a little more snow to parts of SNJ
THE GFS & EUROPEAN MODEL
Both models are pretty close with liquid output of .08" to .11" so they both sit in the 1.0" to 1.5" of snow range for the Delaware Valley.
The DC area ranges from .11" on the GFS and .06" on the Euro. This still puts the snow about an inch or so.
The NYC area shows .03" on the GFS and .05" on the European model. This keeps the NYC area in the coating to at best 1" of snow.
