Regional Weather Summary
National Weather Service State College PA
613 AM EDT Sat Apr 29 2017

Pennsylvania will be in the battle zone between two greatly
differing airmasses this weekend. A wavy, and nearly stationary
frontal boundary will reside across western and southern
Pennsylvania for much of this weekend. Shallow cool air will
filter southward across the Northern Mountains and into the
Central Ridge and Valley and Pocono Mountains Region.

There will be a large temperatures gradient across the frontal
boundary, with highs today ranging from the upper 50s in far
northwestern Pennsylvania, to the mid 80s across the southeastern
piedmont.

Several weather disturbances aloft will race quickly east
or northeast through the state, triggering rounds of
showers, with a few afternoon and evening thunderstorms likely
mainly over the southern half of the Commonwealth.

A few of the thunderstorms over the south and west could be on
the strong side with gusty winds and frequent lightning.

Tonight will be mostly cloudy with scattered showers and isolated
thunderstorms. Low temperatures will range from the mid to upper
40s over the northern tier counties, to the low 60s in the south.

Sunday will feature a similarly sharp temperature difference, but
this time the coolest air will reside across the northeast half of
the state with temperatures only in the upper 50s to mid 60s,
while the Western Lowlands see high temperatures in upper 70s to
mid 80s.

A strong trough and cold front should bring a final round of
showers and thunderstorms Monday into Monday night, followed by
cooler and drier weather for the second part of next week.
