400 FXUS61 KPBZ 301619 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 1219 PM EDT Tue Aug 30 2016 .SYNOPSIS... Warm and dry weather is expected until the passage of late Wednesday cold front. Below seasonal average temperatures are expected for the end of the week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Lowered dewpoint grids for the afternoon, as dry air aloft is mixing down to the surface. Otherwise, few changes to the forecast for now. High pressure will maintain dry and warm weather today as it slides east across the northeastern CONUS. High temperatures should be around 5 degrees above the seasonal averages. && .SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/... The high is progged to move east of the area overnight as a shortwave and associated cold front advance out of the Midwest, resulting in an increase in clouds late. Models continue to show a trend with more available moisture and ascent with the approach and passage of the front Wednesday and Wednesday night. Increased POPs to the high chance category, and opted for scattered coverage wording in the forecast for showers and thunderstorms. SPC`s day 2 general thunder outlook appears reasonable as instability is progged to remain minimal. Shower chances could linger into early Thursday south of PIT as the front completes it`s passage. Building surface high pressure is progged later Thursday and Friday under a Northeast CONUS upper trough. This should result in dry and cooler than average weather to end the week. && .LONG TERM /FRIDAY NIGHT THROUGH MONDAY/... Ridging is progged across much of the eastern CONUS through the period, with dry weather and gradually warming temperatures expected. && .AVIATION /16Z TUESDAY THROUGH SATURDAY/... VFR conditions are expected for most of the TAF period, except for patchy MVFR valley fog through 13Z this morning. Clouds may begin to increase late tonight north of PIT, but ceilings will remain VFR.Winds will remain light through tonight. .OUTLOOK /TUESDAY NIGHT THROUGH SATURDAY/... Restrictions will be possible with a cold front Wednesday into Wednesday night. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None.
