Thursday was pretty much an average day with sunshine, clouds, and then showers and thunderstorms in the afternoon. The showers were in part of a low pressure area, but the heaviest rains occurred well north and west with some severe weather to the south and east across Southeastern PA and into Northern Maryland.
Overnight showers and thunderstorms will continue with lows around 70; Friday will feature morning clouds and leftover showers, but drier air will begin to work in from the northeast. There may still be showers and thunderstorms into the afternoon south and east of Center City with highs in the lower 80s. After some higher clouds overnight Friday with lows in the lower 60s we'll have a continued onshore wind for Saturday with highs in the upper 70s. We'll be in the middle 70s on Sunday with a mixture of sunshine and clouds in the afternoon.
Going to back to work on Monday we still have high pressure parked on top of the region so highs will remain below average with highs ranging from the upper 70s to lower 80s on Tuesday(the average high should be in the middle 80s). Come Wednesday there will be increasing clouds in the late afternoon ahead of whatever tropical system forms off of the Bahamas and travels northward along an offshore trough(but the tropical system shall pass by hundreds of miles to our east). On Thursday there will be a cold front approaching from the west with a chance of showers and thunderstorms by the late afternoon with highs in the upper 80s.
