Area Forecast Discussion National Weather Service Cleveland OH 719 PM EDT Sun Jul 12 2020

SYNOPSIS. Cooler air will settle over the region through Monday as an upper level trough reaches the eastern Great Lakes. Surface high pressure will build in behind the front on Monday and remain overhead through Tuesday. Upper level ridging will build overhead again though midweek.

NEAR TERM /THROUGH MONDAY NIGHT/. Update . The near-term forecast remains valid. Still expect isolated showers and thunderstorms over portions of our CWA to dissipate by around sunset this evening as the boundary layer stabilizes via nocturnal cooling. As a shortwave trough continues to approach from northern ON and the Upper Great Lakes, the airmass may become sufficiently-cold and moist for isolated lake enhanced rain showers and thunderstorms to develop over Lake Erie and move generally southeastward over far-northern OH and northwest PA during the predawn hours of Monday morning. In fact, 18Z/Sun NAM soundings in BUFKIT suggest moderate lake-induced CAPE will develop over Lake Erie overnight tonight. Will reevaluate this potential with 00Z/Mon mesoscale model guidance before making any upward adjustments to POPs and QPF.

Previous Discussion . Scattered showers and thunderstorms have developed this afternoon where a cold front sinking south has interacted with the outflow from overnight convection. In addition, energy moving through the upper level trough will move east across the area this evening. Instability is limited to around 500-700 J/kg of ML CAPE this afternoon with little flow in the column. This is making heavy rain the primary concern as some storms seem to back build or re-develop off outflow boundaries. Storms so far have had a low centroid with pockets of heavy rain from southern Wayne County to southern Trumbull County. Thunderstorm activity will decrease as we approach sunset.

Cold advection will increase behind the front overnight with scattered low level clouds arriving towards morning and thickening with diurnal heating. Otherwise the weather should be quiet with high pressure build south over the area. A secondary piece of energy does move through the upper level trough across the eastern Great Lakes but expecting precipitation with this feature to be east of the area. Highs on Monday will be just a couple degrees below normal in the upper 70s to low 80s. Monday night will be cooler with good radiational cooling and inland areas dropping into the 50s across most of northeast Ohio and Northwest Pennsylvania.

SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/. Mid level ridging will build across the Great Lakes/Ohio Valley region Tuesday through Wednesday, providing dry conditions and increasing temperatures into midweek. A cold front will sink southeast towards the region Wednesday into Wednesday night, as a mid level disturbance and associated deepening surface low tracks northeast along the front. This will bring shower and thunderstorm potential back to the area later Wednesday night, mainly across northwest OH as the front moves into the area. Highs will generally be in the mid to upper 80s Tuesday, with upper 80s to low 80s expected Wednesday.

LONG TERM /THURSDAY THROUGH SUNDAY/. Continued warmth in store with a return to widespread 90 degree weather by the weekend. First, the aforementioned cold front will cross the area Thursday with the boundary becoming diffuse as the main forcing/low associated with it moves northeast through Canada. The lingering frontal boundary may set up across the area Friday into Saturday before generally lifting north of the area. Guidance showing a strong signal for MCS activity to move southeast across the region Friday night through Sunday as mid level ridging builds across the central CONUS. Generally have slight chance/chance pops for now with lower confidence on timing/details of any individual convective system. Highs will generally be in the upper 80s/low 90s Thursday and Friday, with low to mid 90s expected for the weekend.

AVIATION /00Z Monday THROUGH Friday/. Mainly VFR expected next 24-hours. Cyclonic westerly to northwesterly flow aloft persists over our area as a trough aloft and embedded disturbances translate slowly eastward. At the surface, a high pressure ridge builds gradually from the west. Surface winds should trend light and variable between 00Z and 12Z/Mon before becoming northwesterly at about 5 to 10 knots between 12Z/Mon and 00Z/Tues.

Lingering isolated showers and thunderstorms over the region should dissipate with nocturnal cooling by 01Z/Mon. However, lake-enhanced cumuliform clouds are expected to develop overnight tonight into Monday morning over Lake Erie and extend generally southeastward over northern OH and northwest PA. These clouds should primarily be scattered in coverage, but occasional VFR to MVFR ceilings are possible. In addition, isolated lake enhanced rain showers and thunderstorms are possible over and just southeast of Lake Erie during the predawn hours of Monday morning.

Outlook . Occasional non-VFR possible with scattered thunderstorms Wednesday night through Friday.

MARINE. Quiet conditions expected on the lake through the week. Generally northerly winds will prevail across the lake tonight through tomorrow night, with winds becoming southerly Tuesday. Winds will increase a bit out of the south Wednesday night as low pressure moves northeast towards the lake, becoming southwest and it tracks just west and north of the lake Thursday. The attendant cold front will cross the lake Thursday but winds are expected to be generally lighter and variable behind the front through Friday.

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.
