After a period of dry air, showers and thunderstorms will survive the trip into Harrisburg, Pennsylvania, from the Midwest.

There is a risk of downpours heavy enough to cause flash and urban flooding into Thursday night.

The amount of shower and thunderstorm activity may diminish locally Friday into Saturday but is likely to continue south and west of the region.

Temperatures are forecast to remain near or slightly below average through the weekend. Temperatures typically range from a low of 64 to a high of 83 F.

This Day In Weather History

Centre County, PA (1792)
Quote from the diary of William Colbert, a Methodist Circuit Rider up in Centre County: "A very cold morning. It was surprising to see so much snow on the ground at this season of the year. The limbs of the peach trees broke, and large limbs of the oaks broke down, and saplings bent across the road. It began to snow last night before we went to bed. I came out of my way by Lamb's to Phillip Antes."
