Discussion              

An upper-level disturbance will help to develop low pressure today in the southeastern states and this system will intensify as it moves fairly quickly to the northeast reaching the waters off of eastern Maine by mid-day Friday.  Accumulating snow will spread across the region later this evening and it should be over by dawn on Friday likely with accumulation totals of 2-4 inches although isolated higher amounts are possible; especially, in the eastern half of the metro region. Temperatures will drop well down into the teens on Friday night in the wake of the low pressure system and it’ll stay quite cold on Saturday.  A brief warm up into the 40’s on Sunday afternoon will be followed by another impressive cold shot early next week following the passage of another cold frontal system.
