CWS Forecast: Northwest Pennsylvania
Midweek will begin comfortably across Pennsylvania with widespread 70s across virtually the entire state. Dry weather with relatively few clouds is expected. Thursday looks similar temperature-wise. although perhaps a touch cooler north and warmer south compared to Wednesday. However, the skies will be somewhat unsettled as some showers and storms can be expected, particularly north of I-76. Friday’s forecast is a somewhat difficult one as there is strong disagreement on the extent of rain, but as of now, it looks like at least the later part of the day, perhaps overnight, will feature rain across southern and western areas. Temperatures, however, look to continue to remain between 70 and 80 degrees. Heading into the weekend, chances for showers are present in southern areas both days, but the comfortable temperatures look to continue aside from slightly cooler temperature where rain is persistent.
