Area Forecast Discussion National Weather Service Cleveland OH 342 PM EDT Mon Jul 13 2020

SYNOPSIS. High pressure centered over the Great Lakes region will persist through early Wednesday. A low pressure system and associated cold front will impact the area late Wednesday and into Thursday.

NEAR TERM /THROUGH TUESDAY NIGHT/. For the remainder of this afternoon, a shortwave trough will continue to bring minimal impacts to the area. The minimal instability we had which was mentioned in previous discussion has diminished and CIN now dominates the area. Opted to keep isolated PoPs for southern counties in forecast due to some shower development along the southern border of CWA, however reduced the western extent of coverage. Highs today will peak this afternoon in the mid 70s to low 80s across the area.

Cloud cover will quickly diminish into the overnight hours as an upper level ridge build over the area and brings a dry air mass to the region. Tomorrow temperatures will be slightly warmer as winds shift and become southerly with highs in the mid 80s in western OH and in the upper 70s in NW PA, but will remain less muggy with dewpoints in the upper 50s to low 60s across the area. With limited cloud cover, overnight temperatures will be able to fall into the low 60s out east and into the mid 60s in the western portion of the area.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/. Upper level ridge will build east over the forecast area by Wednesday and then shift to the East Coast by Thursday night. The ridge is expected to amplify as well during this transition. Following the upper level ridge will be a broad upper level trough that will move east over the area by early Friday morning. This trough will have a shortwave trough and associated positive vorticity maximum move through the lower Great Lakes region. Moisture fields support increasing mean relative humidity across the area as well with the shortwave trough. Otherwise, a ridge of high pressure will extend southwest into the local area from Maine Wednesday followed by a warm front that lifts north of the area by Wednesday night. A cold front will move east across the area in response to the upper level trough Thursday night. Due to the upper level support and surface features moving through the area, showers and thunderstorms will be an ongoing threat across the area each period. Warm air advection will take place behind the warm front causing dewpoints to also increase back to the upper 60s to lower 70s by Thursday. Destabilization will take place enhancing threat for showers and thunderstorms; especially during the afternoon and evenings. Temperatures will climb into the upper 80s to lower 90s Wednesday and to the upper 80s Thursday. Overnight lows will be in the middle to upper 60s with localized lows around 70 in the western half of the area.

LONG TERM /FRIDAY THROUGH MONDAY/. Nearly zonal flow will set-up for the end of the week across the lower 48 states. This will be short lived as an area of low pressure moves east across southern Canada. Troughiness will extend south into the western Great Lakes by Monday morning but will be quite broad in nature. Otherwise, high pressure will become nearly stationary over eastern Tennessee and make an attempt to cause some fairly strong warm air advection. This warming pattern will be delayed from the mid week arrival that was earlier suggested. This is all due to a slowing of the forward motion of the overall pattern. As the warm air advection takes place, dewpoints will remain well into the 60s to lower 70s through the period. Then, by Monday, a cold front tries to make a run for passing through the area but winds up stalling just west of the forecast area by Monday afternoon. Hence, continued heat and humidity with threats for afternoon showers and thunderstorms. Highs Friday and Saturday will be in the 80s warming to the lower to middle 90s Sunday and Monday. Lows gradually warming each night from the 60s to the upper 60s and lower 70s Saturday night and Sunday night.

AVIATION /18Z Monday THROUGH Saturday/. Primarily VFR conditions are expected for the TAF period. Widespread cloudiness has given way to isolated MVFR conditions at TAF sites with lowering cloud heights. This oscillation may continue through the afternoon as cloud heights linger near the VFR/MVFR threshold. Kept most sites in VFR conditions but will continue to monitor for any increased low level cloudiness across the area.

Isolated showers are expected to develop across the southwestern portion of the area, impacting KFDY, KMFD, and KCAK primarily. MVFR conditions may exist with any of these showers that directly impact any of the terminals.

Winds are expected to be north to northwesterly at 5 to 10 knots, becoming light and variable again during the overnight hours. Tomorrow as an upper level ridge builds over the area, wind will remain light with southerly winds in the west and northerly winds in the east.

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

MARINE. Generally light and variable winds shaping up through Wednesday on the lake as high pressure moves east over the region. High will push east of the area Wednesday and flow will begin to increase from the south Wednesday night. A cold front will move east across the area Thursday night and force winds to shift to a westerly direction and diminish. Otherwise, light and variable flow is expected Friday into Saturday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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