  Moisture streaming north

Posted: 1/17/2010 08:59:00 AM

Low pressure developing over Virginia this afternoon will move north toward Long Island later this evening and tonight, spreading Gulf of Mexico moisture over New England. High pressure will remain intact to the north all the while, funneling colder air south, and changing any rain or sleet to snow by 9pm tonight. The heaviest snow can be expected between 11pm and 4am as the H5 low crosses Long Island.

More details to come as we move into nowcast time.

Snowfall forecast for Keene,NH (Sun-Mon): 6" to 8"
For elevations above 1000ft: 8" to 10"
