Area Forecast Discussion National Weather Service Cleveland OH 646 AM EDT Tue Aug 4 2020

SYNOPSIS. A cold front will drift eastward across the region through sunrise reaching the Ohio/Pennsylvania border shortly after sunrise. A reinforcing surge of cooler air will cross the region during the evening. In its wake high pressure will take control and persist into at least Thursday night.

NEAR TERM /THROUGH WEDNESDAY/. Cold front was located from near Marion to Vermilion then northeast across the central portion of the lake as of 1030Z. The front should be near the OH/PA border by mid morning. Expect to see showers and isolated thunderstorms along this boundary.

The better chances of showers and thunderstorms should be mid afternoon into the evening as a secondary surge of cooler air moves southward across the region. It looks like it will be cold enough aloft to assist with the development of some small hail in the convection during the afternoon/evening, especially across the eastern half of the CWA. Highs this afternoon should be in the 70's.

Convection should move east with the surface trough during the late evening. We will then see what can generate off of Lake Erie as the cooler air associated with the upper level trough moves overhead. Current thinking is we will see some lake effect showers/thunderstorms from the central lakeshore region eastward to NW PA. High pressure building into the NW OH should keep this area dry. It will be cooler tonight with lows mostly in the 50's inland and near 60 along the lakeshore.

A few showers will linger off of Lake Erie from the central lakeshore region into NW PA through at least early afternoon. However the coverage should decrease through the morning. High pressure should take control of the entire region by late afternoon with dry conditions expected. Highs should be in the lower to mid 70's.

SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/. Broad upper level trough will remain over the local area and the eastern United States during this forecast period. The trough will amplify slightly by Friday night. The trough will become centered over the eastern Great Lakes by Friday and shift east of the area Friday night. Surface high pressure will dominate the Great Lakes region through the period as it remains nearly stationary through Friday night. Fair weather should be the rule during the period but on the relatively cool side in the temperature department. Cold air advection will take place in the presence of the high pressure but trend toward slight warming by the end of the period as the center of the high pressure moves just east of the area. Lows will be in the lower to middle 50s Wednesday night, middle to upper 50s Thursday night and Friday night.

LONG TERM /SATURDAY THROUGH MONDAY/. Digging upper level trough over the eastern United States will shift east off the eastern seaboard Saturday and Saturday night with weak upper level ridging taking place Saturday night into Sunday. Upper level ridging will persist over the Rocky Mountains through the period and send pieces of ridging east toward the region during the period. The weak ridges will be interspersed with fast moving shortwave troughs and associated upper level positive vorticity maximums. Persistent high pressure at the surface will remain nearly stationary over the eastern Great Lakes Saturday and Saturday night. The high will eventually begin to shift east Sunday into Monday off the East Coast. This will allow a warm front to lift northeast across the area Sunday night followed by an approaching cold front Monday night. The front appears to stall over the area Tuesday. As time goes on, increasing instability and moisture will take place with the passage of the warm front. This will bring increasing chances for showers and thunderstorms across the area. Temperatures will be in the middle to upper 80s most areas Saturday through Monday. Exception will be northwest Pennsylvania where highs will be in the lower 80s. Lows through the period will be in the upper 50s east to middle 60s west Saturday night, lower 60s east to upper 60s west Sunday night, and middle to upper 60s Monday night.

AVIATION /12Z Tuesday THROUGH Saturday/. MVFR conditions arrive in the wake of the front and in fog ahead of the front. Showers and thunderstorms will move across the region along the frontal boundary and again with a reinforcing surge of cooler air this evening. Cool air aloft may cause some small hail with the afternoon/evening convection. MVFR conditions will occur with the showers/thunderstorms. Showers and thunderstorms will move east during the evening but could linger near the lakeshore into tonight.

Light southerly winds ahead of a cold front this morning will become northerly in the wake of the front.

Outlook . Non-VFR in areas of fog Wednesday morning.

MARINE. Waterspouts will be a threat again for today through Wednesday morning in any showers and thunderstorms that affect Lake Erie. Otherwise, winds will be northwest 10 to 15 knots today increasing to 10 to 20 knots tonight. There will be a brief window tonight of waves in the central basin of Lake Erie around 4 feet and small craft advisory conditions. Will hold off on the advisory for the moment but may need to hoist it later today. Diminishing winds can be expected for Wedneday and Wednesday night from the west. Otherwise, as surface high pressure becomes the dominating feature through Saturday, winds will be light and variable.

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.
