UPDATED FORECAST FOR MONDAY

Posted: 1/14/2007 10:17:00 AM

The NWS has provided the first accumulation forecasts for Monday. The zone forecast for Cheshire County specifies 3-5 inches of snow and sleet. Monday night, the accumulation forecast has been raised from "light" to "moderate." With moderate roughly translating to 2-5 inches, we could be talking about snow/sleet accumulations of 5 to 10 inches by Tuesday morning. As for ice accumulations, we are looking very close to .5 inches of freezing rain accretion. Delay chances for Tuesday are looking better as the timing has shifted over a few hours.

This could be a very dangerous situation for anyone traveling today, tomorrow, or Tuesday morning. Stay tuned for the latest on this developing winter storm.
