An area of low pressure will move from the interior southeastern States toward the Mid Atlantic coastal plain through the day today. The northern periphery of the precipitation shield associated with the system will make inroads as far north as the mid and lower Hudson Valley, bringing the threat for some light snow to those areas, with flurries possible extending as far north as the Capital Region this afternoon. The storm makes a quick departure out to sea by early this evening, and skies clear for the overnight.
A brief break from the action occurs on Tuesday, though clouds will be on the increase during the afternoon hours as a storm gathers strength over the lower Mississippi Valley and heads toward the lower Great Lakes. A secondary area of low pressure is forecast to form along the mid Atlantic coast by early Wednesday morning, bringing some moderate to heavy snowfall to the region during the period Tuesday night into Wednesday. Significant accumulations are possible across the region, and a winter storm watch has been issued for the entire region from the period Tuesday night into Wednesday.
High pressure builds into the region behind the departing system late in the day on Wednesday, and lasts through the end of the work week. Temperatures are forecast to dip back below normal, though the air is not expected to be nearly as cold as the bitter cold readings experienced the past few weeks.
