Synopsis: High pressure will provide dry weather and seasonable temperatures for today and into the first part of Saturday. A weak cold front will move through early Saturday evening, bringing a reinforcing shot of cooler air. A potential winter storm could still affect parts of the state for Sunday. Drier weather will return for early next week as a new area of high pressure settles in.

 

Short Term (Today and Saturday)

 

 An area of high pressure will provide for abundant sunshine and temperatures rising into the 40s throughout the State for today. These conditions will continue into the first part of tomorrow. A weak cold front will move through by tomorrow evening bringing a reinforcing shot of cooler air. There can be a brief period of light rain/snow showers across the northern zones.

 

Long Term (Sunday through Tuesday)

 

  An area of low pressure will develop over the Gulf Coast states and move northeast and offshore along the Mid-Atlantic States. The real challenge with this system remains the phasing of the southern branch with the northern branch of the jet stream. The current guidance consensus seems to be that the phasing between these two features occurs late and as a result the low instead of moving north northeast as a typical nor'easter does, it moves east northeast and the northern extent of precipitation shield goes as far north as the southern tier of the state, meaning that the rest of the state sees no precipitation at all from this storm. However, if the phasing occurs earlier than what guidance is predicting, then the low as a better chance of tracking farther north and the precipitation shield moves farther north with accumulating snow likely for most of the state. Regardless of what happens, drier weather will return for early next week as a large dome of high pressure settles in along the Eastern United States.
