856 FXUS61 KPBZ 240937 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 537 AM EDT Sat Aug 24 2019 .SYNOPSIS... Dry, pleasant weather is expected through the weekend. Rain chances return on Tuesday with a cold front approach. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... With high pressure centered over southern Ontario relatively cool and dry air will continue under northeasterly flow. A comfortable day can be expected with seasonally cool temperatures, dewpoints in the lower 50s, and plenty of sunshine. && .SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/... Dry and pleasant weather with seasonally cool temperatures will continue through the weekend as high pressure remains the dominant feature. && .LONG TERM /MONDAY THROUGH FRIDAY/... A warming, moistening trend is expected early/mid next week as the ridge axis moves east and return flow commences. Southwesterly flow aloft will increase ahead of a deepening upper low across the northern US plains and Manitoba/Ontario region of Canada. Precipitation is possible late Monday night into Tuesday as a weak shortwave and associated warm front move across. However, the main show will be later on Tuesday into Wednesday. Despite some timing differences among the global models, confidence is high with the passage of a cold front sometime on Wednesday, followed by drier and more pleasant weather late week as high pressure builds into the region. && .AVIATION /10Z SATURDAY THROUGH WEDNESDAY/... Surface high pressure will support VFR conditions through the period. With dry air and 5-10kt winds across much of the area this morning, fog is not expected at most sites. However, isolated calm wind along with clear sky has allowed boundary layer decoupling with resulting IFR fog at LBE and MGW. Given this, have added IFR VIS through dawn for those sites only. Fog is not currently expected at other terminals, but may be possible with further radiational cooling. .Outlook... High pressure will maintain VFR conditions through the weekend, with restrictions returning Tuesday with a cold front. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$
