000 FXUS61 KPBZ 191335 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 835 AM EST Sun Nov 19 2017 .SYNOPSIS... Gusty winds today in the wake of a cold front can be expected today along with scattered precipitation changing to snow over the course of the day. The majority of the work week will be dry outside of a chance of precipitation midweek with seasonal temperatures. && .NEAR TERM /THROUGH TONIGHT/... Updated to end the wind advisory, as gusts in the higher elevations are now coming in at 35 MPH or less. Rest of the forecast is on track for now. Previous discussion... A changeover to a rain/snow mix and snow is expected by through the day as strong cold air advection continues in northwesterly flow. The warm and saturated ground will limit accumulation through much of the day. A shortwave will drop through the longwave and cross the area late this afternoon and tonight which will deepen the saturated layer through the snow growth zone somewhat..presenting the best opportunity for accumulating snow mainly along and north of I-80 and in the higher terrain. Even snow, snow ratios look to be relatively low and have opted to keep accumulations under advisory levels. && .SHORT TERM /MONDAY THROUGH TUESDAY/... Monday and Tuesday look dry with temperatures rebounding to slightly above seasonal averages as high pressure builds back in over the region. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... A weak wave passing north of the forecast area midweek will return slight chances of precipitation for locations north of I80 on Wednesday. Dry conditions will resume Thurs/Fri before the next system impacts the region next weekend. && .AVIATION /14Z SUNDAY THROUGH THURSDAY/... Gusty WNW wind and MVFR/local IFR conditions are expected through most of the day with broad upper troughing behind an exiting strong cold front. Rain showers should taper off by sunrise, though scattered snow showers are expected mainly N and E of PIT with cold NW flow and lake/terrain enhancement. A shortwave rotating through the main trough should increase the coverage of snow showers/flurries. Ports N of I 80 have the best chance at seeing brief IFR vsby restrictions. .Outlook... Cig restrictions should continue Sun night in cold NW flow. Restriction potential returns with a Tue cold front and subsequent upper troughing through mid week. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$
