Heat Wave through Wednesday, better chances for storms midweek

Forecast

Best chance of rain and storms this week looks to be Thursday...

THIS EVENING: Stray Storms, Muggy. Temperatures Falling Into the 80s.

OVERNIGHT: Partly Cloudy, Muggy. Lo 72.

WEDNESDAY: Hot & Humid, Hit-Or-Miss PM T-Storms. Hi 96. Heat Index Values Over 100°.

*Severe Thunderstorm Watch for Dauphin, York, Lancaster, Lebanon counties until 10pm*

We’re watching for a few storms to develop this evening as a disturbances crosses northern Pennsylvania. Most of the action has been well north of our region so far, but spotty storms should develop through sunset as we have plenty of instability in place. Any storm that develops could be strong with damaging wind gusts and hail the primary threat. Showers and storms should wrap up by midnight with muggy conditions overnight.

The heat wave continues Wednesday with highs again well into the 90s and heat indices as high as 100-102. Much like today, the majority of the day will be dry, but hit or miss storms are expected to develop toward evening. The severe threat is minimal tomorrow, but coverage of storms could be higher.

A cold front will be draped across Pennsylvania Thursday, likely leading to our best chance of rain this week in the form of scattered downpours and t-storms. The remnants of Elsa will be moving through the Mid-Atlantic at the same time, but it appears most of the tropical moisture will stay south of Pennsylvania with our rain chances mainly coming via the cold front. The front will hang close by Friday, enough to keep the chance for an afternoon t-storm around. Saturday looks dry at this point (and less humid!) as high pressure briefly builds, but a few t-storms will be possible as next weekend wraps up. While temperatures will turn more seasonable later this week, the mugginess isn’t going anywhere! It is summertime after all! Enjoy!
