Forecast discussion

A strong ridge of high pressure will continue to dominate the state of Pennsylvania up until Thursday, bringing in cloudless skies for the state of Pennsylvania. The MOS 1200 UTC run indicates warm temperatures near 90 degrees for the state until Thursday, with lows staying in the mid to upper 50's. On Friday, the GFS is indicating that a cold front from the west will pass through the Southwestern and Northwestern part of Pennsylvania bringing in rain showers for the day and colder temperatures to occur Friday into Saturday dropping into the mid to lower 70's. In addition on Friday, the GFS model predicts hurricane Earl to hit the coast of New Jersey, which will bring in rain showers to Southeastern and Northeastern Pennsylvania regions. The cold front from the west will make its way out of the state of Pennsylvania by Saturday, pushing hurricane Earl up the eastern coast, allowing mostly cloudy skies to occur throughout the state of Pennsylvania with temperatures in the mid 70's.
