Rain returns to Delaware Valley Wednesday, more unsettled weather this week

After what has been the driest start to September in almost 20 years, rain has returned to the area. While the coverage of rainfall isn’t as great as it originally looked like it would be, there’s a chance for drizzle and scattered showers across the region all day Wednesday.
An area of low pressure off the coast will send several rounds of scattered showers to the area, including during the morning commute and possibly again for the afternoon and evening drive. Conditions Wednesday will be generally cloudy and seasonably mild with high temperatures in the middle 70s.
While everyone across the Philadelphia area will have a chance for some rainfall, not everyone will actually see it. In fact, the greater chance of rainfall will be closer to the coast — closer to the area of low pressure that will start to track east Wednesday afternoon into Thursday. Rainfall totals through Thursday night into Friday morning will likely range from about 0.10-0.25 inch in Lehigh and Delaware Valley, with up to 0.5 inch closer to the coast.
By Friday, the pattern will begin to break down as an area of high pressure tries to push in from the north for the weekend. While there is still a small chance for an isolated shower on Friday, drier air looks to begin to filter into the region Friday night into Saturday and Sunday. High temperatures Saturday afternoon look to be in the middle 70s with overnight lows Saturday night dropping into the upper 50s.
Even cooler and drier air is likely to arrive for Sunday and appropriately so with the autumnal equinox and the official start to autumn occurring at 8:43 a.m Sunday. High temperatures Sunday afternoon will be in the low-middle 70s under partly cloudy skies.
Wednesday: High of 76, low of 68, showers
Thursday: High of 78, low of 67, few showers
