Synopsis:

High pressure will slide off the east coast later tonight, giving way to an area of low pressure which will move through the Mason-Dixon Line during the day tomorrow and spread precipitation throughout the state. A Canadian high pressure will then settle in for Friday into the upcoming weekend, however, another disturbance may slide to our south later Saturday bringing the threat of rain and even snow to the higher elevations. Temperatures will be several degrees below normal before a warm up occurs later next week.

Short Term (Tonight through Thursday Night):

Skies will be mostly clear through the early evening before clouds increase during the overnight ahead of the approaching low. Rain will begin to spread into the western zones during the daybreak hours and into the eastern zones in the late morning. Amounts will generally be between 0.25 to 0.50 inches. All of the rain will end by the evening. The winds will increase later Thursday night as a tight pressure gradient sets up due to the departing low and the arriving high pressure from Canada.

Long Term (Saturday and Sunday):

Canadian High pressure will dominate throughout for the upcoming weekend. With that, temperatures will be several degrees below normal as the flow will be out of the north. A disturbance may slide to our south later Saturday night bringing the threat of rain and possibly snow in the higher elevations. Confidence, however, is low at this time as there is significant spread with the models. Both the NAM and GFS bring some precipitation into the state, while the ECMWF keeps the precipitation suppressed to the south.
