COLD FRONT GENERATES STORMS
A strong cold front will move through the Great Lakes later Thursday. This cool pool of air will force storms to develop into the afternoon and evening. Highs will be in the mid- to upper-80s and humid.
HEAVY DOWNPOURS LIKELY WITH STORMS
A FLASH FLOOD WATCH is in effect until midnight for western Pennsylvania. Torrential downpours are possible. Never drive through a flooded roadway. Turn around, don’t drown.
With the humid air, the rainfall rates could add up quickly. Ponding is probable with some localized flash flooding possible. Rainfall could range from half an inch to up to 3″ where thunderstorms repeat in the same locations.
LINGERING SHOWER OR STORM RISK FOR FRIDAY
Friday will be noticeably cooler with highs in the upper-70s and lower dew points.
It will be cooler and less humid with wall-to-wall sunshine for Saturday. Highs will be in the mid-70s. Sunday, a return flow from the south will warm us back up into the lower-80s with mostly sunny skies.
GRADUAL WARMING TREND
While not as hot, temperatures will begin to climb back into the mid-80s by Wednesday.
