The past 30 days have been relatively dry across much of eastern Pennsylvania, while much of western PA has seen a plethora of rainfall. With the recent very warm and humid air, a welcomed stretch of very pleasant summer days will ensue for much of the remainder of the work week. Over the weekend, a better chance for some more organized precipitation will arrive.

After the cold frontal passage on Tuesday, humidity will drop considerably on Wednesday with sunny skies and afternoon temperatures in the low 70’s to low 80’s. This weather song will remain the same for Thursday and part of Friday. By Friday afternoon, dew points will rise into the 60’s as an upper level trough begins to dive into the region. With the approach of the trough, western Pennsylvania will see some showers and thunderstorms arrive in the afternoon and evening. The unsettled weather will move eastward to the rest of the state by Saturday. The aforementioned trough will park over the area through at least the early half of next week, thus frequent showers and storms will persist through this time. Some models hint at a disturbance moving up the Eastern Seaboard late in the weekend that could enhance any shower/storm activity across eastern PA. Temperatures will hover near, or slightly below, seasonal levels during this period as highs will reach the mid-70’s to mid-80’s and lows in the 60’s. For the period from Friday through the middle of next week, some places (especially eastern Pennsylvania) could see several inches of rain with the possibility of flash flooding in heavier showers and storms. Most places across the state will see at least an inch of rain over the next seven to ten days.

Current long-range guidance indicates rather wet and slightly cool weather will occur from now through mid-August.
