000 FXUS61 KPBZ 131711 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 111 PM EDT Sun Aug 13 2017 .SYNOPSIS... Dry weather and seasonable temperature can be expected into mid week. The rain chance will increase thereafter. && .NEAR TERM /THROUGH TONIGHT/... All fog has burned off, and a small patch of stratus remains that should scatter into cumulus clouds this afternoon. Building high pressure under weak upper troughing will suppress precip and support seasonable temperature for the near term period. && .SHORT TERM /MONDAY THROUGH WEDNESDAY/... Surface high pressure, and eventual shortwave ridging will suppress widespread precip for the first half of the week. Weak troughing and orographic lift may support some ridge-convection on Monday and Tuesday, but shortwave support and low level convergence progs are questionable and rain chance remains minimal. Rising heights/shortwave ridging support a forecast of moderating temperature for the period. Expect readings near the averages under the low amplitude flow aloft. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... Daily rain chances are projected to return for the second half of the week as a series of disturbances in general zonal flow crosses the Great Lakes and Upper Ohio Regions. Temperature under this pattern will remain near the seasonal averages. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/...

Building high pressure will ensure VFR this afternoon and evening. Included mention of early morning MVFR fog, however, development looks less favorable than recent mornings based on latest hydrolapse. Will have higher confidence later this afternoon after observing dewpoints during max heating. .OUTLOOK... Surface high pressure is forecast to support general VFR through early next week with exceptions for peri-dawn fog.
