000 FXUS61 KPBZ 220139 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 939 PM EDT Wed Mar 21 2018 .SYNOPSIS... Dry weather is then expected through Friday morning under building high pressure. && .NEAR TERM /THROUGH THURSDAY/... Snow has all but ended for the local forecast area as the parent low pulls well to our east. Residual flurries will taper down over our southeast by midnight. Temperatures will drop into the lower 20s in most locations. Skies will be mostly cloudy at sunrise, but clearing will occur through the day. Despite the breaking cloud cover, highs will only rise into the 30s and lower 40s. && .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/... High pressure building over the Great Lakes will keep conditions dry into the weekend. Low pressure will then track south of the region, clipping southern portions of the forecast area with precipitation Saturday and Saturday night. Temperatures will likely allow precip to start as snow, change over to rain during the day, then finish as snow. Temperatures will remain well below normal. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... Sunday and Monday will be dry with high pressure across the region again. Low pressure will track from the central Plains on Tuesday to Michigan on Wednesday. Precipitation will spread east in advance of the low. Temperatures should be warm enough during this time period that locations south and west of Pittsburgh should generally receive rain, while locations north and east will have snow mix in at night. && .AVIATION /02Z THURSDAY THROUGH MONDAY/... Spotty and brief MVFR/IFR conditions will continue through 03Z or so as the last of the snow tapers off. At this time, expecting VFR conditions for the remainder of the TAF period as a drier air mass moves in. There is a possibility that MVFR ceilings could linger and/or redevelop late tonight and continue through sunrise, but think chances are too low for inclusion right now. Will monitor and amend as needed. Northwest winds will diminish to under 10 knots tonight, but may gust to around 20 knots once again towards midday on Thursday. OUTLOOK... MVFR restrictions remain possible Friday with a crossing shortwave, followed by general VFR through the weekend. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$ is the U.S. government's official web portal to all federal, state and local government web resources and services.
