Discussion              

Low pressure will track nearby today along a nearly stationary frontal boundary zone bringing us more clouds and perhaps a touch of rain at times.  Weak high pressure will try to bring some drying on Friday, but more rain will follow later Friday night and Saturday from strong low pressure that will push to our northwest.  In addition to the rain on Saturday, New Year’s Day, it’ll be unseasonably mild for the 1st day of January and afternoon highs could be near the 60 degree mark. After another mild and damp day on Sunday, sharply colder air will push into the region by Monday following the passage of a strong cold frontal system. This cold blast may arrive with a low pressure system on Sunday night and Monday which could produce some snow in the Mid-Atlantic region…something to monitor in coming days.
