AREA FORECAST DISCUSSION National Weather Service Wilmington OH 640 AM EDT Tue Sep 22 2020

SYNOPSIS. High pressure will provide dry weather through much of the eastern U.S. this week. The remnants of Beta could bring a few scattered showers south of the Ohio River Thursday night and Friday before a better chance of precipitation arrives this weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Surface high pressure will ridge over the Ohio and Tennessee Valleys today with mostly clear skies and very light winds. Some dense fog in the Ohio and lower Scioto river valleys will burn off quickly after sunrise, with only some scattered fair weather cumulus clouds to show for shallow moisture in the south. Temperatures will warm into the middle 70s.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/. High pressure maintains control over the region tonight and Wednesday. Expect some increasing clouds in the Tri state as the remnants from tropical cyclone Beta bring increasing moisture from the south during the afternoon hours. Dry weather will continue with lows a few degrees on either side of 50 and highs peaking from the mid 70s to near 80.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. Short wave will be weakening as it lifts up the Ohio Valley early in the period. There will be an increase in clouds as this system passes. A second short wave will drop out of the upper Mississippi Valley and cross the region Thursday night and Friday. Cannot completely rule out a few showers in southern counties with this second system, but chance looks very low at this point.

A mid level ridge will briefly build into the area on Saturday as the pattern starts a transition. A short wave will cross the Great Lakes Saturday night into Sunday and begin to carve out a long wave trough in eastern North America. This short wave will push a cold front across the forecast area. It is not clear how much moisture will be available, but at the least there will be a chance of showers area wide. There is uncertainty how quickly a secondary short wave will follow into the base of this trough. But it could be as early as Monday which would keep a chance of showers in the forecast through then.

Temperatures will be above normal through the rest of the week. Then readings will drop back and by Monday be below normal.

AVIATION /12Z TUESDAY THROUGH SATURDAY/. VFR conditions with light winds to continue at most TAF sites through the period. LUK visibilities will quickly improve this morning as mist burns off with heating. Expect a possible repeat of intermittent fog at LUK to end the period, though high clouds may impede this to some degree.

OUTLOOK . No significant weather expected.

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.
