New NAM update likes NJ.

Experience reminds me that snow melts faster on roads in March during the day, but I think we see 2-4" on other surfaces. Going to be over 0.40"+qpf so while not a lot of moisture, enough to make couple inches accumulate!

Take a 1-2 inches off this map for initial melting. I, still thinking we see 2-4" widespread in areas you see in blue here.

Don't forget to follow this guy on twitter... He is always downplaying the snow. A big Met from PA,NJ,NY area. Frustrating to see some of his comments sometimes.. Then when he's wrong he says "oh yeah, well, that's why"

Regarding the snowstorm in 2 days.

Steve D: If anything the CMC is the most consistent in the synoptic evolution and thermal profiles since 3 days ago.

Mike M: You thinking Minimal snow?

Steve: I can't rule it out yet, which is annoying, but not going to put out 5" snow maps either.

Mike: Seems like an earlier arrival situation and stronger storm from the nam

Steve: Yeah and that is what troubles me. Stronger storm. Have you seen the WaterVapor?

Mike: totally agree. Jet comes in and shears it apart!

Steve: But of course, models have all these wacky solutions.

NWS Philly briefing package

Overview: An early spring storm system will bring a threat of wintry weather to the region. Precipitation will begin around or shortly after sunrise Friday and spread northward. Many locations will see some accumulating snow.

Snow : Accumulations are expected to range from an inch or less near I-95 and to the southeast, to as much as 4 inches in the Poconos and far northern New Jersey. The snow will start around sunrise Friday over southern portions of the forecast area, and spread northward during the morning hours. The morning commute may be affected near and southwest of the Philadelphia area. The late afternoon commute will likely be affected over much of the region. For the most up to date snow total forecast and probabilistic snow forecasts, please visit www.weather.gov/phi/winter

MAX Snowfall total from this storm

Above image was Max "potential" snow total.

I agree with this and might add to say "localized" spots of over 4" somewhere.

https://twitter.com/LeeGoldbergABC7/...487040/photo/1




Some just give a bigger range but 2"+ seems to be the consensus with models and forecasters.

Which model do you believe?

"It looks like some snow will accompany the arrival of spring on Friday, but accumulations remain very uncertain"

NWS NYNY

CURRENT THINKING IS THAT IT WILL BE COLD ENOUGH FOR ALL
PRECIP TO DEVELOP AS SNOW EARLY FRI MORNING. HOWEVER...LIGHT SE THEN
EAST WINDS SHOULD WARM THE BOUNDARY LAYER ENOUGH TO EITHER CAUSE THE
SNOW TO MIX WITH OR CHANGE TO RAIN ALONG THE COAST...WHERE THE
PRECIP WILL BE HEAVIEST. STORM TOTAL LIQUID EQUIVALENTS COULD RANGE
FROM 1/2 TO 1 INCH. STAY TUNED
And here we go... Upton raised the snowfall amount. WOW!

Who needs coffee when you wake up to this... Upton goes up with the snow totals?
