Area Forecast Discussion National Weather Service Cleveland OH 325 PM EDT Fri Jun 8 2018 .SYNOPSIS... A weak frontal boundary across central Ohio will remain nearly stationary tonight. The front will drift back north on Saturday but will linger over the region through Sunday. A wave of low pressure will track east along the front Sunday into Sunday night. && .NEAR TERM /THROUGH SATURDAY NIGHT/... Convection remains just to the west and south of the area as a weak surface boundary has drifted south across the area. The front appears to be close to the I-70 corridor and that should be the main focus of convection the next few hours. With that said...the storms to the west will likely continue to move east southeast and should clip portions of the area. A gradual weakening is expected as the storms move into a slightly more stable airmass caused by easterly boundary layer winds. Scattered coverage is likely for a few hours this evening with most if not all of the activity south a line from TOL to CAK. Some strong to border line severe convection is possible but those chances will be a confined to the southwest end of the area. At any rate the storms will need to be watched the next few hours. More convection will fire upstream later this evening and will move across the region toward morning. Have bumped precip chances up in the south. Given the proximity of the front more scattered storms are likely tomorrow. Shear and instability will be similar to today so severe chances appear minimal. Coverage of the storms will peak tomorrow evening with the activity diminishing overnight. Earlier was thinking temps tomorrow would be cooler than today but not so sure now. Even though there will be thicker clouds and more precip the day will start off warmer. Have nudged temps up a tad from earlier package with highs Saturday within a degree or two of today. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... Models continue with the frontal boundary across the forecast area on Sunday. Looks like a wave will move through in the morning, hitting mainly in the west, with another more widespread wave in the afternoon/evening. After that models diverge. The GFS and the ECMWF push the front south of the forecast area Sunday night while the NAM has the front lingering across the area, with a low tracking across the area on Monday. Went with the dry GFS/ECMWF solution for Monday. Went with chance pops Tuesday afternoon. GFS moves the next front into the area on Tuesday afternoon, while the ECMWF holds the front back until Tuesday night. Gradual warming trend with the temps. Temps in the 70s on Sunday warming into the 80-85 range by Tuesday. && .LONG TERM /TUESDAY THROUGH FRIDAY/... Nearly zonal flow shaping up over the first half of the forecast period. An upper level ridge will develop off the Pacific Coast and move inland across the Rocky Mountains. The ridge will amplify dramatically over the Mississippi Valley region by Friday causing upper level troughiness to develop over the eastern United States. A cold front will push east across the area with associated showers and thunderstorms Tuesday night into Wednesday. Surface high pressure will build east across the area by Wednesday night. The high will bring in cooler air to the local area and then as it shifts east, warm air advection will begin to develop. Surface low pressure will move east in association with the developing upper level trough with limited moisture associated with it. Showers and a chance for some thunderstorms will move east with the low pressure system. A gradual warm-up will follow the high pressure in the warm air advection pattern in the wake of the high by mid to late week. && .AVIATION /18Z Friday THROUGH Wednesday/... Showers and thunderstorms continue to the southwest and south of the area. We could see more activity bubble up across the southern end of the area but the northern TAF sites should remain dry most of the period. The threat for convection will diminish this evening. More storms are expected to develop upstream overnight and this activity could reach the area tomorrow morning. Will go with some vicinity mentions in the south for the next few hours. Given uncertainties after that will not mention anything late in the period except at FDY. Locations outside of the thunderstorms will remain VFR. The pressure gradient calls for mainly light east winds except near the lake where there will be onshore flow. OUTLOOK...Non-VFR possible in scattered showers and thunderstorms through Tuesday afternoon. && .MARINE... Northeast flow will turn to the east and diminish to 5 to 10 knots overnight. However the East-northeast flow will linger across the lake through the weekend. Choppy conditions will continue through the weekend with an east to northwest flow of 10 to 15 knots. A small craft may be needed at times as winds near the 20kt mark. In additions There will be a stalled frontal boundary south of the lake through the weekend so the shower/thunderstorm threat will be present with the possibility of a complex or two to work across the region. Winds diminish on Monday and turn to the SE Monday night. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...None. PA...None.
