000 FXUS61 KPBZ 260405 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 1205 AM EDT Wed Jun 26 2019 .SYNOPSIS... Isolated showers and thunderstorms are possible with a weak Wednesday disturbance before high pressure brings dry weather on Thursday. && .NEAR TERM /THROUGH WEDNESDAY/... Dry weather and mostly clear skies are expected tonight under a ridge of high pressure. A weak sfc cold front is progged to drop S across Southern Ontario to Lake Erie by this afternoon. Most of the upper support with the front should also stay north of our area, precluding any significant shower/storm chances. Some isolated storms are still possible across the Upper OH Valley Region though as convective temperature thresholds are reached during the afternoon, though a lack of a sfc boundary or shortwave support should keep coveraged confined to isolated. Above seasonal average temperatures are expected. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... The cold front is expected to stay north of the New York-Pennsylvania state border into Friday, so this should generally keep conditions dry. However, it should be noted that the SREF/GEFS both generate precipitation Thursday afternoon, despite a dry forecast from the deterministic models. An upper level shortwave will trigger another chance of showers and thunderstorms Friday. The NAM keeps precipitation well to the north, while the ensembles again show greater precipitation amounts and coverage than the GFS/ECMWF. Instability again will be available for thunderstorms, but wind shear will be lacking for an overall severe weather threat. Temperatures will continue to be slightly above normal. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... An upper level low will drop from Hudson Bay Friday evening to New England Sunday night, continuing a chance of showers and thunderstorms across the region through the weekend. Monday should then be dry before some precipitation moves over an upper level ridge developing across the central United States. Temperatures will drop behind the passage of the upper level low. && .AVIATION /04Z WEDNESDAY THROUGH SUNDAY/... VFR conditions are forecast for the TAF period. Scattered to broken cu will develop with daytime heating. Surface winds will increase with heating as well. South-southwest gusts of 15 to 20kts are possible during the afternoon. .Outlook... No widespread IFR is forecast. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$
