The National Weather Service Baltimore MD/Washington DC has issued Winter Storm Watches for the entire region in anticipation of a major winter storm expected to hit late Saturday into Sunday, with a stark reminder issued for residents to prepare for significant impacts from both the storm and the ensuing prolonged cold, according to the National Weather Service.

As Arctic high pressure from the north drives down 850 mb temperatures Friday night to a bone-chilling -20 degrees C, translating to single-digit lows and mid-teen highs east of the mountains.
