Area Forecast Discussion National Weather Service Cleveland OH 307 PM EDT Wed Aug 12 2020

SYNOPSIS. High pressure will continue to persist across the Great Lakes region through Thursday. Upper ridging will begin to gradually exit the region to the east on Friday. By Sunday, a cold front will approach the area from the west.

NEAR TERM /THROUGH THURSDAY NIGHT/. No changes to previous update.

Previous Discussion . Fairly quiet short term period with high pressure persisting across the area through Thursday night. Highs will reach the low to mid 80s today with a stationary front appearing to exist over the southern portion of our area, characterized by dew points in the mid to upper 60s and by the presence of low-level cumulus clouds. However, the presence of mid-level dry air will inhibit any shower activity today.

Similar setup expected tomorrow, though slightly drier mid- level air is expected to arrive. A few models are indicating some boundary level mixing occurring in the afternoon hours, which could lower dew points into the mid to upper 50s across the area, contributing to highs in the upper 80s to perhaps even lower 90s. A small area of low-level moisture could also arrive tomorrow afternoon in the southeast portion of the area near YNG/CAK. This could result in a few isolated showers, but not expecting any thunder.

SHORT TERM /FRIDAY THROUGH SUNDAY/. Much uncertainty remains for the forecast over the weekend across the lower Great Lakes. The GFS/GEFS/NAM greatly develop and area of convection over the mid Mississippi Valley on Friday that might be convective feedback enhanced and develops an attendant surface low over the lower Ohio Valley and moves that feature into Ohio on Saturday. Meanwhile the 00Z/12Z runs of the ECMWF maintain shortwave ridging over the region with a dry northeast surface flow. The upper ridge on the euro breaks down for Sunday as another trough to the northwest moves east and drags a cold front into the region in the afternoon while never really advecting the deeper moisture to the south into the region like the GFS/NAM. Moisture will likely be slow to move north into the region Saturday so will tend to favor the drier euro solution. The highest chance will be south of US route 30. The approach of the cold front from the northwest on Sunday may help focus showers and storms over the eastern and central portions of the region. Friday will be warmer given the rising 850 mb temperatures and less cloud cover than over the weekend.

LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/. A long wave trough begins to establish itself over eastern Canada and the ne US for early next week. The rather weak cool front on Sunday night will shift southeast and be reinforced Monday night will a stronger frontal passage which may pass nearly dry. A cooler and less humid air mass will build by to the north for Tuesday into Wednesday.

AVIATION /18Z Wednesday THROUGH Monday/. Mainly VFR conditions across the TAF sites this afternoon with VFR conditions expected to persist through the TAF period. A few patches of MVFR bkn ceilings could be possible at MFD/CAK through this afternoon, though coverage is even too sparse to include in the TAFs.

Winds mainly out of the north/northeast this afternoon, 5 to 10 knots with north to northeast flow continuing through tomorrow.

Outlook . Non-VFR possible with isolated to scattered showers and thunderstorms Friday night through Sunday night.

MARINE. High pressure will persist over the Great Lakes through Thursday with predominately east to northeast flow, 10 to 15 knots, expected across the lake. Although a prolonged period of onshore flow is expected, lakeshore flooding does not appear likely. Winds will become more southerly Saturday night, 10 to 15 knots, ahead of an approaching trough but will shift back to northerly, generally around 10 knots, with the passage of a cold front on Sunday night.
