Area Forecast Discussion National Weather Service Cleveland OH 326 PM EDT Thu Jul 29 2021

SYNOPSIS. Low pressure near Toronto will move east into upstate New York while a cold front settles south across the region toward evening. High pressure will build over the region for Friday and Saturday. Another cold front will move south across the area on Sunday.

NEAR TERM /THROUGH FRIDAY NIGHT/. A cold front will move south across the area early this evening and widely scattered to scattered showers and thunderstorms are expected into the early evening. MLCAPE near 2000 j/kg along with effective wind shear near 40 knots may still allow convection to organize and become severe away from the lakeshore counties and mainly east of I-71 until about 22 UTC. Warm Lake Erie may provide some lingering instability into the evening so will continue with slight chance POPs until midnight over the downwind counties in north central Ohio. Later tonight conditions will stabilize further as less humid air filters into the region from the north.

High pressure will build over the region Friday and Friday night and provide generally clearing, cooler and less humid conditions. Highs on Friday will be in the upper 60s to lower 70s with lows in the upper 40s to upper 50s.


SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/. A broad upper trough will be sitting over the Great Lakes and northeast US this weekend. Surface high pressure will depart east from the local area on Saturday, while a mid level shortwave and attendant surface cold front drops southeast through the Great Lakes Saturday night and through the local area on Sunday. This will bring some shower/storm chances to the area, mainly on Sunday, with the highest potential in the northeast part of the forecast area. High pressure will begin to build into the area Sunday night, ushering in cooler and drier conditions. Highs will be in the mid 70s to near 80s during the weekend.

LONG TERM /MONDAY THROUGH THURSDAY/. Surface high pressure will build over the area on Monday, while a subtle mid level shortwave trough digs southeast from the upper Midwest into the Ohio valley by Tuesday. Dry conditions are expected across the area through Tuesday evening with continued cooler temperatures slowly moderating back to near normal by mid/late week. A weakening cold front may drop south into the area on Wednesday, providing the next chance for precipitation across the area.

AVIATION /18Z Thursday THROUGH Tuesday/. Generally VFR conditions are expected to continue this afternoon and overnight as a cold front drops south through the area. There is still the possibility of scattered showers and thunderstorm development that may reduce visibility and ceiling to the MVFR category mainly east of I-71 until about 23 UTC. Drier air will filter south behind the front tonight and Friday and help stabilize the atmosphere. Winds will be southwest to west near 10-15 knots with gusts to near 20 knots ahead of the front and then shift to the northwest and north around 10 knots.

Outlook . Non-VFR is possible Saturday evening into Sunday in thunderstorms.

MARINE. A cold front will cross the lake late this afternoon and early this evening, which will cause winds to shift from westerly at 10-20 kts to northerly 10 kts or less during the evening hours. Winds will increase back into the 10-20 kt range out of the north later tonight, which will bring waves back into the 3-5 ft range from a good portion of the central basin nearshore. Will continue the small craft advisory despite the lull in winds/waves for a period of time this evening. Winds will subside tomorrow afternoon/evening across the lake as high pressure builds in. Winds will stay lighter Friday night into Saturday before increasing out of the southwest Saturday night as another cold front approaches, crossing the lake Sunday. Winds will again become Sunday and Sunday night, becoming lighter and more variable by Monday as high pressure returns, staying lighter and variable through Tuesday.

CLE WATCHES/WARNINGS/ADVISORIES. OH . Beach Hazards Statement through Friday afternoon for OHZ010>012-089. PA . None. MARINE . Small Craft Advisory until 4 PM EDT Friday for LEZ145>148.
