Moderate cold air will follow the passage of a cold front for the upcoming weekend and attention will turn to the Gulf of Mexico and the southeastern states where a lot of moisture will be gathering. A storm will develop near the South Carolina coastline by early Saturday night and move to a position off the New Jersey coastline by mid-day Sunday. This system is likely to bring another round of accumulating snow to the DC-to-Philly-to-NYC corridor from later Saturday night into Sunday morning with several inches on the table. Looking ahead, very cold air will pour into the interior Northwest, Northern Plains, Upper Midwest and Great Lakes next week and the overall active weather pattern will bring additional snow threats to the Mid-Atlantic region.

A chilly air mass has moved into the region as we close out the work week and despite plenty of sunshine, it’ll be a struggle to make it to the 50 degree mark for afternoon highs.

Moderate cold air will follow the cold frontal passage for the upcoming weekend and attention will turn to the Gulf of Mexico and Southeast US where a lot of moisture will be gathering. A storm will develop in the southeastern states by early Saturday night and - depending on the interaction of two separate waves of energy aloft - it could end up pushing far enough to the north and east to have an impact the Mid-Atlantic region with accumulating snow - perhaps mixed with rain at times - from late Saturday night into mid-day Sunday. Looking ahead, very cold air will pour into the interior Northwest, Northern Plains, Upper Midwest and Great Lakes early next week and it looks like it will then spread to the Mid-Atlantic region at mid-week - potentially setting us up for an extended period of colder-than-normal conditions…and likely additional snow threats.
