Snow Forecast Final Call Wednesday March 7 2018

The satellite loop shows the 2 storm with primary low moving east across the Ohio Valley with clouds covering the Great Lakes. Meanwhile the secondary low has already developed faster and further south than previously modeled. That low is centered in North Central Georgia and is very impressive on the satellite radar signature. The big question is what the surface low does once it passes east of the Virginia coast. Does it continue to inch northward before turning east off the New Jersey coast. Or does it move erratically toward the 40N 70W benchmark which would create a colder solution by a handful of miles. This would easily double amounts along coastal areas. The rain snow line basically sets up right on top of us. If you remember last years mid March blizzard that occurred from northern areas of NYC northward. It was literally 10-15 that made all the difference for the coast.This hangs over our head yet again.

Regional radar is beginning to show the area of rain in the Southeast US which is part of the secondary low that is moving northeastward. At least into the first part of tonight we will just see arriving clouds. Snow or mixed precipitation will develop in the early morning hours as temperatures settle in the low to mid 30s.

CANADIAN MODEL WEDNESDAY MARCH 7 2018 7PM

Snow Forecast Final Call Wednesday March 7 2018

The Canadian model for tomorrow evening shows just how close a call this is. Heavy snow is falling over NYC and the northern half of New Jersey, the Hudson Valley and much of Western Connecticut while the rain snow line cuts across Long Island into Central New Jersey. In the end this is too close to call for those areas near the rain snow line. It will all hinge on whether the surface low migrates a bit further east than what is being shown by some of the short range models. More than likely some areas on this map will bust and the bust could be in both directions.
