Area Forecast Discussion National Weather Service Cleveland OH 712 PM EDT Thu Aug 6 2020

SYNOPSIS. High pressure over the Great Lakes region will remain over the area through Saturday. A warm front will approach the region from the south on Monday. A cold front will approach the area from the west on Tuesday.

NEAR TERM /THROUGH FRIDAY NIGHT/. Surface high pressure continues to dominate across the area this evening with mostly clear skies found along the lakeshore. Decreasing cloudiness will continue to be a theme through the evening tonight. Looks like there could be several hours of favorable conditions for waterspouts/funnels to form again early tomorrow morning, though confidence is too low to include any mention at this time. The best chance for any brief waterspouts or funnels to form would be just offshore Erie/Lorain Counties.

Previous Discussion . Surface high pressure will continue to influence the weather across the region through the near term. This will result in low precipitation chances, mostly sunny skies, and near normal temperatures (highs near 80 and lows near 60). The exception to the low precipitation chance is for northwest Pennsylvania where an isolated shower/thunderstorm may be possible tomorrow afternoon.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/. Predominantly zonal (i.e. westerly) flow aloft is expected over our CWA as a subtle high pressure ridge aloft drifts from the Great Lakes region toward the northeast United States and vicinity. Simultaneously, multiple and weak shortwave troughs are forecast to ripple eastward through the aforementioned ridge. At the surface, ridging should affect our area as the embedded high pressure center moves from the eastern Great Lakes to the southern Appalachians. At this point, odds favor fair weather through the period. Saturday afternoon highs in the upper 70's to mid 80's should be followed by Saturday night lows in the upper 50's to mid 60's. Sunday afternoon highs in the 80's to near 90 degrees and Sunday night lows in the 60's to lower 70's are forecast. Humidity will increase through the period as a low-level return flow of moisture from the Gulf of Mexico develops over our region.

LONG TERM /MONDAY THROUGH THURSDAY/. Multiple shortwave troughs embedded in the zonal flow aloft should affect our CWA Monday through Tuesday. At the surface, a cool front should drift eastward through our CWA Monday night through Tuesday as the aforementioned high pressure center meanders over the southeast United States. Isolated to scattered showers and thunderstorms are possible along and ahead of the cool front and shortwave troughs. Monday afternoon's highs should reach the mid 80's to lower 90's and be followed by lows in the mid 60's to lower 70's Monday night. Tuesday afternoon's highs should reach the 80's, while Tuesday night's lows are forecast to mainly reach the 60's.

Flow aloft should become more cyclonic Tuesday night through Thursday as a longwave trough and embedded shortwave disturbances become established over the Great Lakes and vicinity. At the surface, very weak high pressure ridging should build behind the cool front departing generally toward the east. Isolated to scattered showers and thunderstorms remain possible. Overnight low temperatures should remain slightly above-normal (i.e. in the 60's to lower 70's), while Wednesday and Thursday afternoon highs should be near-normal (i.e. in the low to mid 80's).

AVIATION /00Z Friday THROUGH Tuesday/. VFR this evening across the TAF sites and VFR conditions expected to persist throughout the TAF period. Mostly northerly winds will diminish over the next several hours to 5 knots or less. A land breeze could develop at CLE/ERI overnight which would shift winds towards the south.

Outlook . Non-VFR possible with showers and thunderstorms on Monday and Tuesday

MARINE. Winds are expected to trend northeasterly to northerly at about 5 to 15 knots the rest of today through Friday night as a high pressure center meanders over southern Ontario. These winds will veer gradually to southerly and then to southwesterly this weekend as the high pressure center drifts toward the southern Appalachians and continues extending a ridge over Lake Erie. Southwesterly winds of about 5 to 15 knots should veer gradually to westerly Monday night and Tuesday as a weak cold front drifts eastward over Lake Erie. Waves are forecast to be no larger than 1 to 3 feet through the period.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
