Synopsis:
After experiencing early summer-like weather during the first half of the week, temperatures will now continue to settle at or slightly below normal. Cloudy and dreary conditions will continue into the evening before a cold front brings showers and thunderstorms overnight into Friday. High temperatures will differ throughout the Commonwealth as we saw today with southern portions reaching the mid-60's, western regions remaining in the mid-50's, and eastern areas flirting with the 50 degree mark. Saturday will be beautiful, but chilly for most of the state with a few scattered showers. On Sunday, expect mostly sunny skies with temperatures staying in the mid 50's. As we roll into next week, a warming trend will set in as well as some unsettling weather.
Short-Term:
The cold front that's been almost stationary will begin to trek northward as a low-pressure system over Ohio will move north northeastward. A secondary low pressure will develop off the Delaware coastline Friday night that may create some extra energy to any precipitation along the eastward moving cold front. Areas in SE PA may see higher amounts of rain due to this secondary low development. By Saturday, temperatures will be below normal as a trough moves over the area.
Long-Term:
As a short-wave trough creates a low-pressure system over the central plains, a weak ridge east of the system will bring a brief period of above normal temperatures beginning late Sunday night into Monday as this ridge causes warm air advection from the south. By the middle of next week, temperature should stay around average along with unsettling conditions due to a stationary front north of the area.
