CBS3’s Llarisa Abreu thinks the higher threat will be locally heavy rain that could trigger flash flooding.

The cold front stalls south of the region for the start of the weekend. By Saturday, Abreu anticipates the front to lift as a warm front keeping the chance for showers in the forecast.

Temperatures won’t be as high this weekend and dew points will stay in the mid-60s.

Storm chances appear to stick around into Sunday, mainly late in the day. The pattern stays unsettled early next week.

The average last day for 90-degree weather in Philadelphia is Sept. 1.
