On Sunday, a cold front will move across central Pennsylvania, bringing with it sporadic showers and thunderstorms. After that, there will be a major cool-down, with temperatures falling far below average for late August.
The Harrisburg region is expected to see sunny, warm weather on Saturday, with highs in the 80s.
That’s not the case on Sunday. Tomorrow afternoon and evening are expected to bring rain and storms as a cold front moves over the state from west to east.
Although the National Weather Service does not predict severe weather, the storms may produce lightning and brief heavy rains. Before the cold front moves through, daytime highs will be in the 70s and 80s, just like on Saturday.
A significantly cooler weather pattern will replace the stormy weather by Monday morning. The next week will have below-normal temperatures due to Canadian high-pressure systems.
Morning lows in some places may drop close to 50 degrees, while daytime highs are predicted to be 5–15 degrees lower than usual for late August.
The extended outlook predicts a cold, dry week.
