626 FXUS61 KCLE 171805 AFDCLE Area Forecast Discussion National Weather Service Cleveland OH 205 PM EDT Mon Aug 17 2026 .WHAT HAS CHANGED... The forecast remains on track and no major changes were needed with this update. && .KEY MESSAGES... 1) The next chance of widespread showers and storms will be with a cold front on Wednesday. && .DISCUSSION... KEY MESSAGE 1... A cold front will move east across the area this morning. Scattered showers are possible this morning with a few thunderstorms possible near the front in southern zones during peak diurnal heating this afternoon. The best instability will be to the south of the CWA so severe weather is not expected. From there, dry weather is expected tonight through much of Tuesday night. By early Wednesday morning, rain chances will increase ahead of a southeastward-advancing cold front. Showers will progress southeastward across the area Wednesday morning into the afternoon and there may be some convection inland from Lake Erie during the afternoon. Overall, instability seems meager in comparison to recent days and guidance suggests that QPF will be relatively light so the chance of severe weather and heavy rainfall are low at this point. A dry and cooler air mass will arrive behind the front Thursday and Friday with below normal highs in the 70s and lows in the 50s expected. && .AVIATION /18Z Monday THROUGH Saturday/... There remains some lingering mid level ceilings 1500-2500 ft across central and eastern terminals this afternoon. Conditions have improved to VFR behind an eastward tracking cold front. Expect for lingering MVFR ceilings to improve to VFR as the cold front exits to the east later this afternoon into early this evening. VFR ceilings will continue this evening through the remainder of the TAF period. Patchy mist/fog is expected to develop tonight into early Tuesday morning. Primarily MVFR ceilings are expected in any BR/FG with IFR possible at MFD. Northwest winds 5-10 knots this afternoon will become light and variable overnight before becoming westerly at 5-10 knots late in the TAF period. Outlook...Non-VFR possible on Wednesday with showers and thunderstorms. && .MARINE... North flow around 15 knots this morning may produce waves in the 2 to 3 ft range in the central basin of Lake Erie, with a moderate rip current risk through the morning hours. High pressure gradually builds in tonight and tomorrow, with gradually improving conditions. Southwest flow develops Tuesday afternoon/evening ahead of an approaching cold front, with wind speeds peaking in the 15-20 knot range Tuesday night. Current forecast calls for 2-3 ft waves in the central and eastern basins of Lake Erie, with a low chance of 4 ft waves if we get a few hours of 20 knot winds. The cold front crosses the lake on Wednesday, with winds turning northwest Wednesday evening and then northeast Thursday into Friday as high pressure builds in from the northwest. && .CLE WATCHES/WARNINGS/ADVISORIES...
