Synopsis:
The cut off low to our west will finally make movement eastward as the Commonwealth continues to get rain for the rest of the work week. A strong high pressure system looks to make way into the region on Sunday.
Short-Term:
The cold stationary front will slowly begin to exit the commonwealth by the end of the week, causing showers and possibly thunderstorms ahead of this front. They will travel from Southwestern PA toward the Northeast direction. Flash flooding is a major concern as these showers can drop an inch of rain in about a 20 minute interval. The front will pass through Wednesday night, shifting the direction of precipitation from south to westward. The cutoff low to our East will finally re-enter the jet stream and exit. Scattered showers are still seen throughout Thursday but the threat of flooding should not be as worrisome.
Long-Term:
The cutoff low will finally be pushed back into the jet stream by a strong storm system associated with a cold front. A strong high pressure system will push through the area Friday, leaving us with a possibility of scattered showers as remnants of the cut off low. Showers could still linger on Saturday morning, but should clear up after noontime. The high pressure should dominate Sunday, leaving us with sunny conditions.

A cold front will push through the Commonwealth Wednesday bringing large chances of precipitation. A strong high pressure moves in for the rest of the week bringing partly sunny skies and temperatures back up to the mid-60s by the weekend.
Short Term:
A high will continue to move out of the area as we head into Wednesday night. A low pressure system will come up the east coast, bringing slightly cooler temperatures for the rest of the week. This will bring in cloud cover and a chance for precipitation for most of Thursday. Temperatures will drop significantly Thursday night, reaching the high 30s in some areas. Winds around 10-15kts will be felt going into Thursday night as the front passes through. Cloud cover will slightly dissipate as a high hovers above the commonwealth which will stick around for the weekend.
Long Term:
Temperatures should stay in the high 50s/ low 60s as we head into the weekend. Saturday and Sunday bring warmer temperatures as well as mostly sunny skies across the commonwealth, as cloud coverage dissipates Saturday morning. Temperatures will stay in the mid-60s throughout the weekend, leaving us with a few remnants of summer.
