Area Forecast Discussion National Weather Service Cleveland OH 342 PM EDT Sat Jul 24 2021

SYNOPSIS. A warm front will move eastward across northwest Pennsylvania late this afternoon. A cold front is expected to sweep across the region on Sunday. High pressure will increase its influence on the region from the west Sunday night with the high located over Ohio by Monday night. The next cold front crosses the region on Wednesday.

NEAR TERM /THROUGH SUNDAY NIGHT/. Warm front continues to move eastward across NW PA taking the remaining showers with it. Our attention will then shift to Michigan where a cold front will assist with the initiation of thunderstorms through the evening. A few of these storms during the evening could drift across NW OH and maybe cross Lake Erie with some stronger wind gusts. For the most part it looks like the storms will be decreasing in intensity as they cross the region late this evening into the overnight. However we will need to monitor closely. Brief heavy rainfall will accompany the the thunderstorms that move southward through the morning. Fortunately these storms should have a good forward speed so the threat of flooding is low.

There should be enough breaks in the cloud cover this afternoon to allow highs to reach the mid 80's across the central and western CWA. It will definitely feel much more humid into the overnight. Lows tonight will be on the warm side with upper 60's to lower 70's common.

Outflow from the thunderstorms should move southward across the CWA through the morning hours and should become the primary focus for thunderstorms through the afternoon. So for now the thinking is that most locations will be dry by mid afternoon. One thing for us to monitor will be the actual cold front that will lag its southward movement slightly. This boundary could generate a few showers late afternoon into the early evening across the southeastern half of the CWA. COnfidence is not high in this potential but it is something for later shifts to monitor. Highs on Sunday look to be in the 80's for most locations.

High pressure is expected to increase its influence on the region Sunday night. Clearing skies, light winds and recent rainfall may allow for fog formation early Monday morning. Lows will range from the lower 60's across inland NW PA to near 70 along the lakeshore.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/. By Monday morning, west to northwest flow aloft will be entrenched across northern Ohio and northwest Pennsylvania. Precipitable water values will range from 0.8 to 1 inch across the forecaster area and deeper moisture will be displaced south from Mid Mississippi Valley to Mid Atlantic state line early Monday. Surface high is expected to be positioned over central Illinois on Monday. Expecting dry conditions with temps slightly above norms for lows and highs Monday and early Tuesday.

Upper level ridge over the plains is expected to build and amplify yielding a more northwest flow across the Great Lake region. Euro and GFS are showing a wave diving southeast from Lake Superior to Lake Ontario late Tuesday. This feature may yield a few showers and isolated thunderstorms across the forecast Tuesday afternoon and Tuesday night. Surface base capes of 1500 to 2000 j/kg Tuesday afternoon and 800 to 1000 j/kg Tuesday night may be in play. Precipitable water values are expected to rebound to 1.25 to 1.5 by Tuesday afternoon.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. Lingering showers and a few storms are possible across the central Ohio Wednesday morning. The synoptic pattern will remain in place through the week with the ridge building over the Plains. This will allow the trough remain over the northeast and northwest flow over the forecast area through week. Precipitable water values will decrease with the passage of the wave Tuesday night . expecting values to drop to slightly below 1 inch Wednesday afternoon and rebound Wednesday evening. As a result, moisture will increase from west to east Wednesday night into Thursday. A stronger wave is expected dive southeast and track across the forecast area Thursday morning. A possible thunderstorm complex is possible associated with this wave. There is still a great deal of uncertainty with the placement of the initial convection on Thursday. Will maintain rain chance with thunderstorms for Thursday and linger into Friday.

High temperatures for this period will begin in the mid to upper 80s on Wednesday and a slight cool down to the low to mid 80s by Friday. Overnight lows will also follow a gradually cooling trend, beginning in the mid to upper 60s on Wednesday night to the low to mid 60s on Thursday night into Friday morning.

AVIATION /18Z Saturday THROUGH Thursday/. Warm front continue to move eastward across extreme NE OH into NW PA this afternoon with scattered showers and maybe a couple rumbles of thunder. Our attention will then shift to Michigan where a cold front will assist with the initiation of thunderstorms through the afternoon. The only MVFR will be with the showers across the east through the afternoon. The convection that moves southeastward with the cold front from Michigan will provide MVFR ceilings and brief IFR with the heavier downpours for the late evening into the overnight hours.

Southwest winds are expected through the evening. Gusts to 20 knots will be possible across NW OH. As the line of showers/thunderstorms passes overnight winds shift to the west and northeast at 10 knots.

Outlook . Non-VFR possible in fog Monday morning. Non-VFR also possible in showers/thunderstorms Tuesday night into Wednesday.

MARINE. Southwest winds of 10-15 knots as the warm front moves across the lake this evening. Waves should remain between 1-3 feet. A cold front will move east across Lake Erie on Sunday. This will yield a wind shift to east to northeast or 5-10 knots. High pressure will build across the lake behind the frontal passage which will allow calm conditions across the lake to persist through mid-week. Due to the relaxed pressure gradient flow, a wind shift is expected along the lakeshore associated with a lake breeze during the afternoons. No marine headlines are expected at this time.
