Synopsis...
A weak cold front will pass through the state this afternoon and evening, bringing with it a slight chance of showers to western portions of the region. The only chance of any precipitation after today for the forecast period is in the northwest region where some lake effect rain showers may persist into later Friday afternoon. A few snow flakes may even show up around Bradford tonight. After today, a westerly flow will persist for the remainder of the forecast period with breezy conditions into Saturday and clear skies into Monday.
Short Term...(today - noon Friday)
Aforementioned weak fropa will cross the western part of the state this afternoon and evening. The 540-thickness line makes its appearance as far south as the Mason-Dixon line according to NAM and GFS later tonight into early tomorrow morning, thus a chance of snow seems prudent in the northwest mountains overnight with the lake-enhanced precipitation. After tomorrow morning, skies begin to clear across the state as a high pressure sets up to the southwest of the region. A fairly tight pressure gradient will create breezy conditions from tonight into tomorrow.
Long Term...(noon Friday - Monday)
Not a whole lot going on in the long term. A persistent westerly flow and clear skies will create some pretty seasonable conditions for the weekend and early next week. Looking into the even longer term, the GFS, DGEX, and ECMWF are all hinting at a possible storm system moving up the east coast in the middle part of next week. Based on the current track and surface temperatures, there will be no shot for snow anywhere near PA but it is something to keep an eye on as far as some potential significant rainfall.
