Scattered showers and isolated thunderstorms will move southeastward across Lake Erie early this morning and traverse the remainder of the Commonwealth through the afternoon and evening. A few storms may produce strong to locally damaging wind gusts over the southeastern portion of the Keystone state. High temperatures will range from the low 80s in the northern and western mountains to the low 90s across the south central valleys and southeastern piedmont. Today will be the warmest day out of the next 7, and could be the last surge of late summer heat prior to the end of the month. Showers and storms will exit the Delaware Valley early tonight. A northerly breeze will bring cooler and less humid air into the northern tier of Pennsylvania overnight with low temperatures around 50 degrees early Monday morning. This will mark the start of a cooling trend in Pennsylvania. Temperatures will be noticeably cooler through the middle of the week with the best chance of showers and thunderstorms on Wednesday. After today, any rainfall may ultimately be hard to come by even into the second half of the week as Hurricane Erin moves away from the East Coast. $$ MRS
