Big Weather Changes For PA Begin Now

Some relief from the scorching heat is in sight this week, following torrential downpours that left as much as 3 inches of rain in some parts of the region.

A "brief blast of September-like air" will move in to Eastern Pennsylvania this week, AccuWeather says. Conditions should dry out Monday, but a few afternoon thunderstorms are still possible.

The storms will bring in cooler and less humid air.

“Monday may set up to feel more like fall from northeastern Pennsylvania to New York City and New England as clouds and areas of rain and drizzle make for a damp start to the week,” AccuWeather Meteorologist Brett Rathbun said.

High temperatures will be in the low 80s through the weekend. Some showers are possible early Tuesday morning. And a round of thunderstorms could move through Thursday and Friday, forecasters predict.

If the forecast holds up, however, it looks like a beautiful weekend is on tap.
