FXUS61 KCLE 041657 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 1257 PM EDT Tue Aug 4 2026 .WHAT HAS CHANGED... There were no impactful changes made to the forecast this morning. && .KEY MESSAGES... 1) Dry conditions continue today before a series of low pressure systems mark the return of showers and thunderstorms chances Wednesday afternoon through late week. && .DISCUSSION... KEY MESSAGE 1... High pressure will linger into Wednesday, keeping dry conditions and plenty of sunshine across the area. As this high pressure drifts east midweek, a weak low pressure system centered near the Gulf Coast will move north into the Ohio Valley. This system will bring scattered showers and thunderstorms to the eastern portion of the CWA Wednesday afternoon into the evening. Given the positioning of the low and the higher PWAT axis further east, there remains a decent chance that the bulk of the area remains dry. Given the overall weak forcing with this system, not anticipating any severe weather at this point. Late Wednesday into Thursday, a broad upper level trough and associated frontal boundary will approach the area from the west. This frontal boundary will be slow moving and potentially stall near the area until pushing east on Friday. As a result, multiple rounds of showers and thunderstorms are possible Thursday and Friday. The confidence in any severe threat is low at this point given the discrepancies in timing amongst models, but increasing dew points and daytime instability keep that potential around for the end of the week. In addition, will need to keep an eye on the potential for heavy rainfall as mean flow is expected to be near parallel to the frontal boundary which could result in periods of training showers. Given the expected PWAT values and deep warm cloud layer, can also expect any storms that develop to be associated with efficient rainfall rates. WPC has highlighted the entire area in a marginal ERO for Thursday into Friday. The chance of showers will linger into the weekend as additional disturbances push across the area, although full spatial extent and timing remains uncertain. Through the weekend, temperatures will remain near normal for this time of year with highs climbing into the mid to upper 80s and overnight lows cooling into the 60s. && .AVIATION /18Z Tuesday THROUGH Saturday/... VFR conditions will continue for this TAF update through Wednesday morning. Skies will be mostly clear. Winds will be light and variable 5 knots or less.

Outlook...Widely scattered showers and thunderstorms with non- VFR conditions possible across northeast Ohio and northwest Pennsylvania Wednesday afternoon and evening.
