Local Forecast Discussion

Tonight: A shower early (maybe with a rumble of thunder), then clearing, warm and humid with patchy fog. Low: 71

Tuesday: Turning out mostly sunny and hot, but a bit less humid in the afternoon. High: 94

Tuesday Night: Mainly clear and more comfortable. Low: 66

First it was the heat on Monday, which soared into the 90s again today and allowed Allentown and Philadelphia tie their record while Reading set a new record high of 97. Then there were a few rounds of strong, lighting-filled thunderstorms. These storms also brought heavy downpours that caused flash flooding and wind gusts that exceeded 50 miles per hour. Aside from a shower through midnight, the night will be dry from here on out. However, it will be warm and humid with some patchy fog as the skies clear out a bit. Overnight lows will once again remain in the 70s.

Tuesday won't have the record challenging warmth Monday did, but highs will still reach into the low and mid 90s. Dew points will also drop a bit on Tuesday, so it won't feel as humid. As for the cloud cover, look for skies to turn out mostly sunny. Wednesday will be fairly similar to Tuesday with plenty of sun, lower humidity levels and highs in the low 90s. Despite the heat (which may be too much for some) Tuesday and Wednesday will be the nicest days overall through this weekend.

Thursday won't be too bad either, but highs will again top out in the 90s and the humidity levels will be on the rise. The atmosphere will also become more unsettled again on Thursday, so by the end of the day be on the lookout for a shower or thunderstorm in a few spots.

The unsettled weather will then continue into this weekend as highs return to the 80s.
