THIS EVENING: Mostly Cloudy. Temperatures in the 70s.
TONIGHT: Cloudy, Drizzle Late. Lo 67.
THURSDAY: Scattered Light Showers. An Afternoon Thunderstorm Possible. Hi 80.
Despite multiple layers of clouds today, we snuck in a few peeks of sun which allowed temperatures to get back to 80 degrees (or close to it). Clouds will thicken up tonight as a southeast flow combines with the approach of the remnants of Bertha. The main rain shield is expected to stay west of the Mid-state toward Pittsburgh, but showers will develop locally by mid-morning, with drizzle possible pre-dawn. The primary band of showers is expected to exit during the early afternoon. There have been hints in higher-resolution guidance that a few thunderstorms could re-develop during the late afternoon across our western counties. Should this happen, we will have to watch for an isolated strong storm or two given the dynamics that will be in place from the former tropical storm. Thursday will be a warm and very humid day with highs in the low 80s and dew points climbing closer to 70.
A cold front will approach the commonwealth on Friday, and ahead of it, more widespread thunderstorms are expected to develop Friday afternoon and evening. It’s still a bit early to gauge if widespread severe weather will happen, but a few strong storms will certainly be possible given the dynamics and warm, humid air that will be in place. Friday is still expected to be our warmest day with mid-80s likely for a high,
The front may get hung up a bit across the southern tier on Saturday, so the chance for a stray shower will remain, though most neighborhoods look to be dry. By Saturday night, cooler, drier air barrels in as temperatures fall into the 50s. The cooler air will have some staying power early next week as highs remain in the low 70s and lows potentially drop into the upper 40s for some Monday and Tuesday mornings. The good news? Plenty of sunshine and low humidity in store with this air mass!
