Quotes from meteorologist Steve D. Just fascinating stuff. Storm well into New England but take a look at the precip shield to the south.

https://twitter.com/nynjpaweather

Precipitation shield appears to be growing from C PA down to VA. Interesting trends. .


Going to study upper level dynamics. Might be forming some stretching, deformation over the region.

Now the combination of a tight thermal gradient at 850 MB to the surface and upper level divergence had enhanced rising air over the region.

As a result lifting is becoming enhanced, the atmosphere is cooling, and the precipitation is intensifying.

This process eventually will cause all precipitation is turn over to snow and surface temps to crash below freezing.

Rain/snow line starting to push into NW NJ this hour. Should reach Philadelphia in 90-120 minutes.

Fascinating watching the rain/snow line move east. Light stuff. Watch for Black Ice on wet roads where temps drop below 32 tonight

My sister sent this to me. Near Cuba NY. 5 inches of snow.

I guess the people that didn't take a scarf today will be pretty cold on the commute home.

Band of snow heading into Philadelphia metro next 45 minutes

That station next to Trenton reporting snow is http://forecast.weather.gov/MapClick...6#.UpZoD2Uo5Ms

Current Surface Pressure. 990mb Low over Maine right now. Not often we see precip linger this far back.

Dry air working into the system and its wrapping up now. Philly(PHL) reported sleet for a little bit but precip is evaporating now south to north.
