Dry and tranquil weather will continue in Pennsylvania through 
midweek. Expect a mild trend into the second half of the week with
high temperatures on Friday forecast to be 10 to 20 degrees above
average for late December. 

A late-week storm will bring more rain to the Keystone State
Thursday night through Friday. Heavy rain is possible across the
eastern part of the Commonwealth and could result in small stream

Gusty winds behind the late-week storm will direct colder air 
back into Pennsylvania for the weekend. Rain may mix with or
change to snow over the western half of Pennsylvania Friday night. Lake-
effect snow showers should bring a light accumulation to the 
northwest snowbelt and higher elevations of the western 
Alleghenies Friday night into Saturday. 

The soaking to potentially heavy rain followed by gusty winds and
lake-effect snow may cause pre-Christmas travel delays. A weak 
system may bring light snow to some parts of Pennsylvania on 
Christmas Eve.
