NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Jun 11, 4:36 PM EST, 44 minutes earlier.
Area Forecast Discussion National Weather Service Pittsburgh PA 536 PM EDT SAT JUN 11 2016 .SYNOPSIS... Shower and thunderstorm chances will increase this afternoon and tonight as a cold front approaches. Dry and cooler weather is then expected Sunday and Monday. && .NEAR TERM /THROUGH SUNDAY/... The early eve update featured only cosmetic and timing adjustments to hourly trends as warm mid level air has inhibited widespread convection. Focus for scattered evening convection will continue to be remnant boundary sagging across the Pittsburgh area. Given instability, dry air aloft, and mid level wind field, marginally severe wind gusts will remain the slight severe threat. A cold front will cross late tonight, too late to tap into the potential this afternoon. Enough moisture and instability should remain for at least a few showers/thunderstorms along the passing front, but coverage is not expected to be widespread. The front itself will usher in an airmass change with cooler and drier air. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/... High pressure will rule for Sunday night and Monday, with dry weather and comfortable dewpoints. Sunday night temperatures will be several degrees below normal, while values on Monday rebound towards climatology. The ridge across the Mississippi Valley and the Deep South will start to flatten later on Monday and into Tuesday. The CWA will remain in the northwest flow pattern aloft. Weak ripples riding the flow may generate some scattered showers and a few thunderstorms Monday night and Tuesday. Maintained low chance pops during this period. Temperatures will creep upward as low level WSW flow develops. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... The northwest flow pattern will continue into Thursday. Kept mostly chance PoPs in the forecast through then with hard-to-time waves dropping through the flow. A more significant wave may drop through the area Thursday night, pushing the storm track to the south. High pressure is then expected for Friday and Saturday with drier weather. Temperatures near or just above seasonal levels are forecast through the period. && .AVIATION /22Z SATURDAY THROUGH THURSDAY/... VFR conditions are forecast through the period with gusty winds persisting through the evening. Isolated to scattered thunderstorms will mainly plague ports from BVI to LBE. A cold front will arrive late tonight. Lack of moisture along the front should limit shower potential, although cloud cover will increase. Also, winds will shift from southwest to northwest with the passage of the boundary. .OUTLOOK /Sunday Night through Thursday/... VFR conditions are expected through the early part of next week. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. &&
