... A heat wave through Sunday then a cold front will bring cooler weather Monday through most of next week.
NEAR TERM /UNTIL 6 PM THIS EVENING/... No changes to current forecast previous discussion below...
Rising heights and strong warm air advection will provide a hot and humid day across the region. All heat related headlines remain in place.
Shortwave trough will cross the Great Lakes this afternoon and then dive southward on the eastern flank of the ridge. Position of the ridge, and timing off the wave will be crucial to placement of late afternoon convection. Models are not in very good agreement with timing or scope of possible convection, but will keep in PoPs across a portion of the region late this afternoon. Atmosphere will be plenty unstable, so a stronger, to isolated severe, cell cannot be ruled out. Additionally, with dewpoints in the 70s, storms will be capable of producing heavy rain.
SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/... Convection that develops this afternoon will dissipate during the evening as the atmosphere stabilizes and the upper level wave moves southeast of my FA.
The heat and humidity will continue into Saturday. The heat advisories/warnings will continue into Saturday with apparent temperatures being relatively similar each day. A cold front will begin crossing the region Sunday, bringing showers and thunderstorms to all locations.
LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... The front will complete its passage of the forecast area Sunday night, although showers will linger into Monday morning to the south and east of Pittsburgh. Behind the cold front, high pressure will dominate the Great Lakes region with much cooler temperatures.
