Fire Weather Planning Forecast
National Weather Service Pittsburgh PA
1240 PM EST Mon Nov 17 2025

.DISCUSSION...

Fire weather potential remains low over the next 24 hours as a new
disturbance tracks into the region and returns rain and perhaps a
brief period of snow and wintry mix. Precipitation chances quick
ramp up after dawn on Tuesday and continue into the late evening
hours. Precipitation amounts will likely range from a tenth of an
inch to half an inch. Localized higher amounts may be measured in
the ridges due to the effect of upsloping. Drier conditions
expected Wednesday.

Wind gusts will likely diminish after dark and become variable
through early Tuesday.

Forecaster: Hefferan
