000 FXUS61 KPBZ 221252 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 752 AM EST Wed Nov 22 2017 .SYNOPSIS... Scattered snow and rain showers will be ending this morning and much colder air will overspread the region. Dry weather can then be expected until the approach of the next front on Saturday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/...
-- Changed Discussion --
Updated to expand the area of scattered rain/snow showers for a few hours in the northwest flow behind the cold front. Activity will linger longest north of I-80 and along the ridges. Had a mixed rain/snow shower pass over the office just recently. With the moisture quickly becoming shallow, some of the activity will likely taper to drizzle before ending. However, freezing drizzle should not be a major concern given the relatively warm ground and temperatures struggling to get below freezing. Temperatures are on track for the most part, with not much movement upward expected.

Ensemble forecasts are showing the next cold front dropping through the area on Saturday with fairly weak support for precipitation, followed by the next trough setting up over the Eastern CONUS.
