Area Forecast Discussion National Weather Service Cleveland OH 352 AM EDT Sun Aug 9 2020

SYNOPSIS. High pressure centered over the Ohio Valley will continue moving southeast today. A warm front will lift northeastward across the region on Monday. A cold front will cross the area on Tuesday. High pressure will return to the region on Wednesday.

NEAR TERM /THROUGH MONDAY/. Sunday will feature the last quiet weather day of this stretch with high pressure sliding southeast of the area. Southwest flow will return to the region on the west side of this system, allowing for temperatures and moisture to increase across the region. Upper ridging over the area will allow for dry conditions, but the influx of moisture will allow for some diurnal cumulus to be the main problem of the day. High temperatures will be several degrees warmer than Saturday and some locations may see 90 degrees for the first time in several weeks. Overnight lows will remain warm in the 60s with some clouds entering the region and warmer daytime highs.

A warm front will approach the area on Monday and will promote warm temperatures once again with perhaps more widespread lower 90s across the region. The main question with this front is precipitation potential. The supporting shortwave trough appears to have slowed through the Great Lakes region and therefore, the best timing of rain has shifted slightly later in the day. Have PoPs increasing through the afternoon hours on Monday, but the best rain chances appear to be beyond the near term forecast period for much of the forecast area. Some instability over the region will allow for some thunder potential and have thunder mentioned for Monday afternoon.

SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/. By the beginning of the short term forecast period, an upper level ridge that persisted over the area during the weekend will begin to be replaced by an upper level longwave trough, resulting in upper westerly flow across the area. Multiple shortwave disturbances are expected to move along the periphery of this longwave trough and impact the CWA throughout the week. Beginning on Monday night, a frontal system approaches the area from the west as the ridge exits the area to the east. Ahead of the cool front moving across the area on Tuesday, winds will be from the southwest due to the back edge of the high pressure system. This will allow for ample moisture advection into the region from the Gulf of Mexico, resulting in the return of humid conditions. The cool front should move through the area by Tuesday afternoon/evening. Scattered showers and thunderstorms are possible Monday evening through Tuesday evening with the approach and passage of the front. Current models have limited vertical winds shear associated with this system, however moderate forecast instability values, a very moist atmosphere, and some models suggesting upper level support with a short wave trough may allow for a few pulse thunderstorms to become strong, with strong winds being the primary threat.

Another weak high pressure is expected to build into the area Tuesday night into Wednesday. Opted to keep chance of scatter showers and thunderstorms in the forecast on Wednesday as lingering moisture and diurnal instability cannot completely rule them out. High temperatures on Tuesday and Wednesday will be in the low to mid 80s, with humidity returning across the area. Low temperatures overnight will dip down into the mid 60s.

LONG TERM /THURSDAY THROUGH SATURDAY/. During the long term period, the long wave trough will continue to slowly progress eastward as embedded shortwave troughs also continue to propogate eastward throughout the period. Behind this trough, a ridge of high pressure begins to build across the eastern US, however a low pressure building in the Mississippi Valley is expected to undercut this ridge during the long term forecast period. Over our area, it is forecast that a weak high pressure remains over the area, however models begin to diverge towards the end of the period with handling this next system. Kept chance of PoPs in for the majority of the forecast period due to the diurnal cycle interacting with the lingering moisture over the area. High temperatures during this period will be in the mid 80s with overnight lows near the mid to upper 60s.

AVIATION /06Z Sunday THROUGH Thursday/. High pressure centered overhead this morning will allow for VFR conditions to continue through TAF period. Some spotty cirrus has been overhead this morning and as high pressure slides southeast, some better moisture will enter the region and diurnal cumulus should form over the region this afternoon. Any lower clouds should dissipate late this evening. Showers and thunderstorms to the west of the region may allow for some cirrus clouds to move in tonight. Winds will be generally southwesterly through the period as high pressure moves to the southeast.

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

MARINE. High pressure will continue to persist over Lake Erie for Sunday and part of Monday. Winds today will be from the southwest at 5 to 10 knots in the western basin and 10 to 15 knots in the eastern basin. By Sunday night, winds will become more southerly and weaken to 5 to 10 knots across the entire lake and persist until Monday afternoon as the high pressure shifts towards the southern Appalachians. A cold front should move across Lake Erie Tuesday afternoon, causing winds to become more westerly. Ahead of and with the passage of this front, showers and thunderstorms are possible, which have the possibility of producing locally stronger winds and higher waves. High pressure is expected to build back in across the area on Wednesday into Thursday, allowing winds to become northeasterly at 5 to 15 knots. Throughout the entire forecast period, waves will likely be between 1 to 3 feet. No headlines are expected 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. 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.
