THIS EVENING: Showers & Storms, Heaviest N & W of Harrisburg. Temperatures Falling Into The 70s. Winds: Light.
TONIGHT: Scattered Showers. Lo 64. Winds: SE 5-15 mph.
THURSDAY: Scattered Showers, Slow Clearing. Hi 75.
One round of storms went through areas west of the Susquehanna earlier, and now we’re waiting on additional storms to move in from the north this evening. The atmosphere remains most prime for storm development over the far western communities like Lewistown and Chambersburg, while the rest of the area remains on the cooler and more stable side of the stationary boundary. While showers or storms are possible anywhere, the heaviest action should remain well northwest of Harrisburg and over the mountainous areas. Storms will wind down this evening, but additional showers will develop overnight as the front remains draped nearby.
The front will be slow to clear the region for Thursday. Showers will be around during the morning, and an axis of steady rain is likely over our eastern counties tomorrow morning as the boundary moves toward the coast. We slowly clear out Thursday afternoon as temperatures stay in the 70s tomorrow thanks to east flow and cloud cover. There could be some sun by tomorrow evening, but it could take a good chunk of the day to see it.
Friday and Saturday should be dry with heat and humidity ramping up a bit too. Saturday’s highs could reach 90° while we break into the low 90s Sunday. Earlier, it appeared a late day storm or two would be possible, but there doesn’t appear to a spark for activity this weekend until perhaps late Sunday night. Some showers will linger into Monday morning but should gradually exit by the afternoon. Behind the front, Tuesday looks sunny and comfortable. No extreme or prolonged heat is expected anytime soon as the hottest air stays over the central part of the country. In a nutshell, typical summer weather for Central PA is here to stay. We’ll keep you posted on the timing and intensity of the storms later today so check back.
