000 FXUS61 KPBZ 181817 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 217 PM EDT Thu Oct 18 2018 .SYNOPSIS... Anticipate dry and cool weather outside of the upcoming weekend period. Chances of rain will increase Friday night as one system moves through. The second system will increase rain and snow chances Saturday afternoon into Sunday morning. && .NEAR TERM /THROUGH TONIGHT/... Beyond cool NW flow producing stratocu to the east of Lake Erie...expect clear skies to persist. Slight ridging aloft plus increasing surface pressure and clear skies will lead to another cold night...with near freezing temperatures across the area. However...enough wind mixing will prevent any sort of deeper freeze and need for any freeze warning products. && .SHORT TERM /FRIDAY/... The upper level trough will approach from the west...reaching the western Great Lakes by Friday afternoon. Clouds will slowly increase through the afternoon with southwest sfc winds...but dry weather will continue. && .LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/... The first upper level disturbance will cross Friday night...producing light rain showers across the area. A second disturbance and more potent surface cold front will quickly follow Saturday afternoon and provide more chances for precipitation. Rapid cooling at the 850mb level Saturday evening will allow snow to quickly mix with rain...and continue to turn over to snow for most areas by Sunday morning. Dry air working in behind the system will quickly squelch precipitation chances during the daytime Sunday...save for isolated lake effect light rain and snow showers. Cool and dry weather resume through the next work week. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... While some low VFR stratocu will continue through the afternoon hours at FKL/DUJ, by sunset all sites are expected to be clear. Winds should remain under 10 kt from the northwest, with winds backing to the southwest overnight. Outlook... Widespread restrictions and rain are likely with a Fri night/Sat cold front. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$
