000 FXUS61 KPBZ 210826 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 426 AM EDT Thu Sep 21 2017 .SYNOPSIS... High pressure will maintain warm, and generally dry weather into early next week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Dry and warm weather expected today. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/... Mid/upper ridging will enhance over the Eastern U.S. in response to Western troughing and TS Jose. Dry and warm weather will thus prevail through Saturday. Expect temperatures about a dozen degrees above the averages. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... Little change is foreseen in the overall circulation pattern through at least Tuesday, with the western trough/eastern ridging pattern persisting. The upper ridge may start to be knocked down by and approaching Upper Midwest shortwave by the end of the period, but any frontal precipitation likely won`t arrive until after Wednesday. && .AVIATION /09Z THURSDAY THROUGH MONDAY/... Fog has not been as widespread in Ohio as would have been expected given a bit of rain yesterday, higher dewpoints, and clear skies. However, fog satellite product imagery is starting to indicate valleys are saturating, especially near KFKL, KHLG, and near KLBE, so these locations look most likely to crater out. Elsewhere, dewpoint depressions indicate saturation may be limited to a short window around sunrise when some slight restrictions will be possible. At KDUJ, drier air got in there on Wed evening, so while a short window of light fog may be possible, it`s almost as likely they will just remain VFR. All sites will be VFR within an hour or two of sunrise, regardless. Fries .Outlook... Other than local morning fog, no widespread restrictions expected under high pressure. && .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.
