Scattered showers and thunderstorms will develop out ahead of a cold front this afternoon and move southeastward across the Commonwealth through the evening. A few storms may produce strong to locally damaging wind gusts. 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 days. 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. Elsewhere, lows will generally be in the 60s. Temperatures will be noticeably cooler through the middle of the week with cloudier skies and easterly flow. The highest chance of showers and a few thunderstorms will be on Wednesday. However, 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. $$
