Intervals of sunshine will be mixed with varying amounts of mid and 
high level clouds today. Temperatures soaring into  the 70s at most 
locations this afternoon will approach, or exceed all-time record 
highs for the month of February across Pennsylvania.

Mostly cloudy, breezy and very mild conditions are on tap for 
tonight, with low temperatures only dipping to 55 to 62 degrees in 
most locations. 

Strengthening low pressure will move northeast across the Upper 
Great Lakes late today into early Saturday. The cold front trailing 
from this low will bring a few rounds of moderate to heavy rain 
showers Saturday morning in the west, and during late morning and 
afternoon hours across Central and Eastern Pennsylvania. A narrow 
line of strong to potentially severe thunderstorms with gusty 
westerly winds and small hail are possible along and just ahead of 
the front Saturday.

The main thing to take to heart is reality will return to the
commonwealth Saturday.
