Synopsis:

After a weekend of fall-like temperatures, a weak front will pass through the commonwealth on Monday bringing clouds and a few showers to the majority of the state.  Temperatures will stay in the 60s on Monday as the sun will find trouble breaking the clouds.  Following the passing of the front, winds will turn northerly drawing cool air throughout the whole state on Monday night.  High pressure will then build across the Northeast associated with cool temperatures and sunny skies for the rest of the work week.

Short Term:

Both the 18z NAM and GFS show a weak disturbance crossing the state from Northwest to Southeast on Monday. Rainfall amounts associated with this precipitation will be minimal.  Most of Pennsylvania should expect cloudy skies and a few showers before the front passes.  Temperatures on Monday will hover in the upper 50s and 60s, with cooler temperatures in the Northwest regions of the State.  On Monday night, temperatures will dip into the 40s across the state, and as low as the mid-30s in northern areas of Pennsylvania. 

Long Term:

It will be an uneventful week of weather after Monday as high pressure will build over the Northeast.  Temperatures will hover in the Mid 60s across the state, with warmer temperatures by Thursday and Friday.  Night time temperatures will dip into the upper 30s and 40s for the majority of the state.  Expect sunny conditions and low humidity with dew points in the 40s.
