000 FXUS61 KPBZ 230712 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 312 AM EDT Fri Sep 23 2016 .SYNOPSIS...
-- Changed Discussion --
After another warm day today, a weak cold front passing tonight will bring cooler temperatures for the weekend.
-- End Changed Discussion --
&& .NEAR TERM /THROUGH SATURDAY/...
-- Changed Discussion --
Mid and high clouds have moved into northwest PA and eastern OH in advance of a developing New England upper trough and a weak cold front. Expect more cloud cover across the north into the afternoon, with temperatures to continue more than 10 degrees above average ahead of the front. The weak boundary will cross and exit the area Friday night, and while a sprinkle or two is possible no POPs will be in the forecast, as moisture is limited and the better dynamics continue to be well north of the region. Temperatures will be decreasing back toward normal values Saturday
-- End Changed Discussion --
&& .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
-- Changed Discussion --
High pressure will bring near seasonal temperatures and dry conditions through Sunday night. An approaching area of low pressure will bring increasing dew points and a chance for showers later Monday.
-- End Changed Discussion --
&& .LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
-- Changed Discussion --
Models coming into better agreement with slow moving storm system from the Great Lakes translating east with an associated cold front into Wednesday. Models still differ on strength and speed of system, so Superblend was used for much of the forecast period with chance POPs through Tuesday tapering to isolated showers Wednesday. Dry and cool high pressure will dominate late week.

&& .AVIATION /07Z FRIDAY THROUGH TUESDAY/... VFR conditions with high clouds increasing overnight. High clouds will continue to move through the area during the daylight hours, with a non-restrictive mid-deck spreading over the area from north to south late in the day and into the evening hours. .OUTLOOK /THURSDAY NIGHT THROUGH MONDAY/... Restrictions are possible tonight and into Saturday morning, as cold front sinks southward through the region. A popup shower cannot be ruled out with the passage of this boundary, but visibility restrictions are not expected. After the low clouds clear southern ports Saturday morning, no widespread restrictions into early Monday. Possible restrictions Monday with the next strong cold front, however timing in model solutions continue to be an issue. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None.
