Fire Weather Planning Forecast
National Weather Service Pittsburgh PA
135 PM EST Thu Nov 27 2025

.DISCUSSION...
Snow showers, more numerous and heavy along and north of
interstate 80, will continue through Friday early afternoon as
cold advection and shifting towards northwest flow aloft
continues. Height rises and building high pressure from the west
should taper off snow activity through the day Friday, with most
of the region dry Saturday.

Below average temperature will persist while area wind slowly
subsides through Friday night as high pressure builds.
