.DISCUSSION...
 
Area of low pressure responsible for light to moderate 
accumulating snowfall will continue to move eastward off the 
Atlantic seaboard overnight. Much colder temperatures and gusty 
northwest winds up to 30 mph can be expected through tonight as 
the system departs. Breezy conditions and RH values between 30-35 
percent are expected on Thursday, with full sun helping to melt 
leftover snow. Warming temperature trend Friday into the weekend 
with temperatures trending above normal. No significant 
precipitation is expected through the weekend as high pressure 
associated with the milder temperatures becomes established.
