Area Forecast Discussion National Weather Service Cleveland OH 358 AM EDT Sat Aug 8 2020

SYNOPSIS. High pressure will become centered over the area today before sliding southeast for Sunday. A warm front will enter the area on Monday. Low pressure over the northern Great Lakes on Monday night will extend a cold front across the area on Tuesday. High pressure will return to the region on Wednesday.

NEAR TERM /THROUGH SUNDAY/. High pressure and an upper ridge over the region will allow for dry and clear conditions today. A couple clouds may form near the lake this afternoon and some thin cirrus aloft may enter during the day. Other than that, the only important item for today is that temperatures will continue their recovery towards normal and most areas will reach the 80 degree mark, perhaps pushing more into the mid 80s in NW Ohio. Overnight temperatures will be fairly similar to this morning in the upper 50s to lower 60s across the region. High pressure slides southeast for Sunday and a push of warm air will enter on the back side of this system, allowing for highs to increase further into the mid to upper 80s. Conditions appear dry for Sunday as moisture remains limited over the region and the best forcing for convection will be after the near term period.

SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/. The primary focus of the short term period will be a frontal system that will move across the area Monday night into Tuesday behind the surface high pressure that will begin to move into the southeastern US. A series of shortwave disturbances will begin to impact the area during the short term period in association with a low pressure system centered near Hudson Bay. One of these weak shortwave disturbances will move across the area Monday night into Tuesday in conjunction with a frontal system that will progress eastward during the time. The frontal system and upper level support will bring chances for scattered showers and thunderstorms to develop across the area Monday into Tuesday. Moisture values will begin to increase during this period as winds increase from the southwest. Increased humidity is expected to return to the area during the period. High temperatures on Monday will be in the 90s ahead of the front and will be a bit cooler on Tuesday with highs in the mid 80s. Overnight lows during the period will be in the upper 60s to low 70s.

LONG TERM /WEDNESDAY THROUGH FRIDAY/. For the beginning of the long term period, the broad scale pattern is more stable as a broad upper level trough becomes established to the north of the Great Lakes region through Thursday allowing for primarily cyclonic flow to prevail over the area. Although there is a dominant flow, the CWA continues to have the chance to be affected by shortwave disturbances that exist along this longwave pattern. On Wednesday, a weak surface high pressure will build in over the area, however moisture values remain ample and upper level support from the shortwave trough will allow the potential for multiple rounds of scattered showers and thunderstorms to remain possible through Thursday, especially in the afternoon and evening, as diurnal factors will likely contribute to storm development. High temperatures during Wednesday and Thursday are in the mid 80s with lows in the mid 60s.

Models begin to diverge a bit in consistency on handling the end of the week system. A ridge appears to build over the eastern US, including the CWA. However, a surface low pressure moving north from the Mississippi Valley may move over the area or to the west of the area at the same time that a shortwave begins to push the ridging pattern to the east Friday night. The general consensus amongst models is that the ridge does begin to move out which should allow for isolated showers and thunderstorms across the area. Exact positioning is where the most uncertainty is at this point. Highs on Friday will be in the mid 80s with overnight lows in the mid to upper 60s.

AVIATION /06Z Saturday THROUGH Wednesday/. High pressure settling over the Great Lakes region today will allow for mostly clear and VFR conditions. Some scattered cumulus may develop near Lake Erie this afternoon but should offer no restrictions. Winds will be light and variable over the region with high pressure in the vicinity.

Outlook . Non-VFR possible with afternoon showers and thunderstorms on Monday through Wednesday.

MARINE. High pressure over the area will allow light and variable winds to persist across Lake Erie today. This high will shift towards the southern Appalachians by Monday which will result in the winds shifting to the southwest by Sunday morning and increasing to 5 to 15 knots. On Monday night, a cold front is expect to move across the lake which will result in winds shifting and becoming more westerly behind the front at 5 to 10 knots. By Tuesday night, high pressure is expected to once again build over the area which will allow for calm winds again across the lake. Waves during this forecast period are expected to be between 1 and 3 feet. There are no headlines anticipated at this time.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
