The storm moving from the Ohio Valley to the Middle Atlantic coast will cause snow and ice, Clearing should follow tomorrow, but another storm should bring snow and ice followed by rain from Maryland to Massachusetts.
The surface analysis shows to low pressure area off the North Carolina coast, a large cold high pressure area in the northwest corner of the map, and a broad northeasterly flow of cold air between pressure centers. Cold will continue in this whole area through Saturday.
In reaction to this, the flow aloft may become more southwesterly over the Eastern states. This would promote less chill in the Northeast but cause more storminess. The following maps are U.S. model predictions of total snowfall and precipitation from now through next Wednesday.
Is there any warmth in future? The following two maps suggest the answer is yes, but it is only temporary. This map shows projected flow aloft for next Tuesday. If you trace the origin of the air, you see a southwesterly flow of air next Monday (March 2).
New York City often has its coldest days when the air comes straight south through the Hudson Valley... rather than from the Great Lakes. This map shows how today's wind flow matches the profile for extreme cold.
There will be a non-uniform snow accumulation pattern because the precipitation will be organized in bands and blobs around which precipitation rates vary quite a bit. This map is designed to give a quick overview about expected snow accumulations:
NOAA's Climate System Forecast suggests above-average temperatures for much of the Midwest and some of the Northeast for the second week in March according to this map. Meanwhile, these areas will remain in the deep freeze through tomorrow night.
This forecast map for Thursday evening shows the cold wave in full swing. A storm in eastern Maine is forcing bitter winds from eastern Canada straight across the mountains to blast the I-95 corridor. Snow showers are common; warmth totally absent.
