The storm Friday night into Sunday will produce a swath of snow north of I-70 and I-80 from Missouri to New England. The heaviest snow of up to a foot will fall across New England where the storm will intensify at the last minute. Most areas will get 1-6 inches of snow. If the NAO was going negative, we could be talking about a much bigger storm, but it's basically a storm that attacks the cold air just like we have seen with the past couple of storms.
New York City will get some snow which will probably mix over to sleet and perhaps some rain. Areas from Philly on south will get a wintry mix changing to rain. Detroit and Cleveland should get a decent storm with up to 6 inches accumulating.
The heat is on from the Plains into the East.
The storms will continue around the edge of the heat wave.
Severe storms will be moving around the ridge of high pressure whish is producing the high heat.
Heat wave will build in the Plains as temperatures will hit the 100s. That heat is heading east this weekend.
A cold front moving through the Northeast will bring heavy storms. High heat will build in the Plains and spread across the East.
The stormy weather will remain in the Plains today and probably tomorrow before the heat builds in.
