000 FXUS61 KPBZ 201625 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 1125 AM EST Mon Nov 20 2017 .SYNOPSIS... Tuesday night through Wednesday morning will be the next chance for precipitation. Otherwise, dry and seasonal conditions are expected through the work week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/...
-- Changed Discussion --
Visible satellite imagery has revealed fairly widespread snow cover this morning north of I-80 as well as in the higher terrain of PA/WV/MD. Where snow is on the ground, temperatures even as of 11 AM remain mired in the upper 20s. Even away from the snow cover, a fairly cold start has not really been overcome as current temperatures do not exceed the mid 30s anywhere. That said, particularly where snow cover remains, high temperatures were dropped back fairly significantly for this afternoon, while areas without snow cover should still at least challenge 40 degrees.
