As of 3pm, showers appear to be limited to Garrett, Preston, and Tucker counties in our forecast area. Thunderstorm activity has remained farther south and east. The showers should come to an end before sunset. Most locations should have some fog Sunday morning, although overall cloud cover is not as expected to be as much as it was today. After fog clears, partly to mostly sunny skies are forecast. High temperatures should be similar to today`s values.

&& .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
-- Changed Discussion --
Any chance of rain during the beginning of the work week will be contained to locations south and east of Pittsburgh, primarily in the highest elevations. Stuck with only shower mention on Monday and added a chance for thunder on Tuesday. Temperatures will slowly rise, allowing temperatures to climb back above climatology.

&& .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
-- Changed Discussion --
Conditions are expected to remain dry for Wednesday, but an unsettled pattern will develop for the rest of the extended forecast. ECMWF and GFS still show general agreement of a system crossing the eastern half of the United States, but continue to differ in the specifics. The best chance for rain currently appears to be Thursday night. Wednesday will most likely be the warmest day of the week, then daytime highs will be slightly cooler through Saturday.

&& .AVIATION /19Z SATURDAY THROUGH THURSDAY/...
-- Changed Discussion --
Thunderstorm chances have become very limited at LBE/MGW as precipitation appears to have pushed east of the terminals. Diurnal cumulus will dissipate around sunset. With cloud cover not expected to be as widespread Sunday morning compared to today, fog appears to be a greater threat than stratus. With 18Z TAF issuance, brought all terminals down to IFR visibilities. No restrictions are expected after fog scatters out Sunday morning. .OUTLOOK... Surface high pressure is forecast to support general VFR through early next week with exceptions for peri-dawn fog.
