There’s a low chance for a few isolated pop-up showers and storms this afternoon/evening, with the highest chances over the ridges in southwest PA and northeast WV. Higher rain chances move in late tonight and Wednesday as low pressure crosses the area.
Lawn and plants getting a little thirsty? There is hope on the horizon! Our region has a very good chance of getting at least 0.10″ of rain over the 36-hour period ending at 8 PM on Wednesday.
