Area Forecast Discussion National Weather Service Cleveland OH 318 PM EDT SAT SEP 17 2016 .SYNOPSIS... A slow moving cold front across the Central Lakes will move across the forecast area tonight...and finally move east of the area on Sunday. High pressure will build across the area Sunday night. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... Cold front just into NW Indiana. Models continue to move it slowly across the forecast area tonight. Spc continue to have the Eastern2/3 or the forecast area in a marginal risk this afternoon and evening. Ahead of the front capes only 500-1000 J/kg...but there is 25-35 knots of shear. Precip over the Western third of forecast area now...will expand as it moves East into slightly more unstable airmass over NE OH/NW PA. Think most precip should be east of the forecast area toward midnight local...although the front will not exit the area until Sunday. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY NIGHT/... Left chance pops going in the East Sunday with the front lingering across the NE OH/NW PA. Cooler and drier air move into the area from the West Sunday night as high pressure builds over the area. Models continue to move a weak front through late Monday night into Tuesday...but timing still differs. GFS a little slower with the front than ydy so left low chance pops into Tuesday morning. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... Not many changes to the long term today. Most of next week will see zonal flow and as a result mild temps and dry weather are expected Wednesday through Friday. Late in the week a potent upper trough will dive south over the northern plains. This will eventually force a warm front north across the area. Have gone ahead and put some small precip chances in for Friday night into Saturday. Lot's of uncertainty with this scenario as the ECMWF keeps the area dry through the end of the period. Will let later shifts make adjustments as the forecast picture becomes clearer. One thing is pretty certain though...temps will remain mild with highs in the upper 70s or lower 80s the entire period. && .AVIATION /18Z Saturday THROUGH Thursday/... Currently not getting any thunder but have been watching the line of showers move across the area. This line will be the main weather maker this afternoon and will try to time it across the area. Most locations remain VFR but pockets of MVFR continue across the area with a few spots of IFR as well. Will go with a few hour period of prevailing MVFR rain at all sites this afternoon. The line should be east of the area by 00z. Although some of the guidance is showing move development to the west of the line toward evening will keep things dry. Do expect widespread MVFR fog and cigs to develop this evening with areas of IFR after 06z given the warm and moist airmass. Only slow improvement is expected Sunday morning. S to SW flow will continue to gust to 20 knots this afternoon. Speeds will quickly diminish this evening. OUTLOOK...Non-VFR possible through Sunday in showers and possible thunderstorms. && .MARINE... Winds have been slow to come up on the lake but see no reason to make changes to the small craft advisory at this point. If things continue as they are the evening crew may be able to cancel early. After midnight the flow will diminish fairly quick. Light SW flow will then continue till a cold front crosses the lake on Tuesday. The flow will become W to NW behind the front but speeds will be light so no headlines anticipated. High pressure and light winds are expected for the middle part of the week but winds will return to the south for the end of the week. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None. MARINE...Small Craft Advisory until 4 AM EDT Sunday for LEZ145>149. && SYNOPSIS...DJB NEAR TERM...DJB SHORT TERM...DJB LONG TERM...Kubina AVIATION...Kubina MARINE...Kubina
