&& .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 /09Z TUESDAY THROUGH SATURDAY/... VFR conditions are expected for most of the TAF period, with the exception of patchy mvfr fog before daybreak mainly at southern ports. Winds will remain light through Tuesday. .OUTLOOK /TUESDAY NIGHT THROUGH SATURDAY/...
