THIS EVENING: A Few Showers SE Of Harrisburg. Temperatures In The Upper 70s.
OVERNIGHT: Partial Clearing, Warm. Lo 70.
SUNDAY: Hazy Sun, Hot, Stray PM T-Storm West Of Harrisburg. Hi 90.
A weak area of low pressure riding up the Chesapeake could bring a few showers to parts of Lancaster, York, and Lebanon counties this evening. Any rain that falls will be light and should quickly end overnight as the system pulls away. It will be muggy with lows again only dropping to around 70.
Sunday will feature more sunshine which will allow temperatures to climb back to 90 degrees. A pop-up storm is possible during the afternoon over the higher elevations, but the vast majority of the area will be dry. The heat intensifies as we head into next week with a pop-up storm or two possible both Monday and Tuesday.
The worst of the heat and humidity arrives toward the middle and end of next week as a southerly flow pushes highs near 90 and dew points around 70. This will result in triple digit heat indices for several afternoons next week along with daily storm chances as a front approaches. The greatest chance for beneficial rain will come Friday with the passage of the cold front. For those that don’t like the heat, there is a light at the end of the tunnel with drier and cooler air poised to move in next weekend!
