Race against time for accumulating snow

There is about a 4-6 hour window for accumulating snow in the I-95 corridor this evening. If you live within 10 miles of I-95, then you have the possibility of picking up 2-3″ of snow in that window. If you live northwest of I-95 by more than 10 miles, than you will likely see another 2-3″ of snow in the before midnight. Here are some the factors that will impact this evening’s weather:

  • The sun has set, and there is no longer any radiation coming through the clouds. As a result, there is a better chance of the snow sticking on pavement.
  • The temperature near the surface is dropping to at or below freezing as night falls and a cold northerly wind howls.
  • Some of the heavier precipitation from the storm will be over Southern New England this evening.
  • At the same time, as the storm gets closer to us, some milder air is moving toward Southern New England from the south. This milder air is not at the surface, but about one mile up in the atmosphere. When this layer of milder air arrives, any snow should change to sleet or rain, possibly freezing rain in the areas where the temperature is below 32°
  • The timing of the milder layer of air reaching SNE is between 8pm and 12am. Until then, let it snow!
  • If there is an updated snow map, it will be for 1-3″ near I-95, and 3-5″ farther to the NW
