000 FXUS61 KPBZ 220510 AAC AFDPBZ Area Forecast Discussion...UPDATED National Weather Service Pittsburgh PA 110 AM EDT Wed Aug 22 2018 .SYNOPSIS... An upper level disturbance will lead to scattered showers today before high pressure builds into the region late in the week. && .NEAR TERM /THROUGH TODAY/... Cold front will slowly cross the area overnight. Line of showers is advancing eastward ahead of the surface boundary and would expect this to continue. Have based overnight PoPs on the track of the front, which will clear the entire area before dawn. Although the front will exit to the east, plenty of residual moisture will lag behind today, allowing for the development of cold-advection showers today. Low-level lapse rates will rapidly steepen today and another shortwave trough will swing through. Thunderstorms cannot be ruled out today, with impressive cooling aloft and some modest surface destabilization. With sustained cloud cover and episodic showers, temperature will struggle to climb into the 70s. && .SHORT TERM /TONIGHT THROUGH FRIDAY/... As high pressure builds tonight night and Thu, moisture will erode and rain chances evaporate. Amid this building high pressure, general sun is expected, but temperature will reach only into the mid 70s on Thu. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... Temperature will recover toward seasonal average by the weekend as a flat upper ridge builds nwd slowly. But an active belt of stronger mid-level flow nwd of the ridge will be found in the Ohio Valley, which could promote active weather Sat/Sun/Mon pending any shortwave troughs embedded in that flow. && .AVIATION /05Z WEDNESDAY THROUGH SUNDAY/... MVFR cigs are through much of the forecast with a crossing upper trough. This trough should also result in sct showers. VFR is expected to return by late aftn/eve as sfc high pressure begins to build in. Outlook... Restrictions are possible with a weak weekend trough. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$
