Cleveland woke to clear skies and temperatures around 66 degrees Tuesday morning, but the calm stretch has an expiration date. Sunshine will push the afternoon high to about 80 degrees before rain chances return late Tuesday night and Wednesday.

Sunny Tuesday, Storm Chances After Dark

Tuesday should stay dry and sunny, with northwest winds increasing from around 1 mph in the morning to about 8 mph by afternoon. The air should feel less humid later in the day, and no rain is expected through Tuesday evening.

Clouds build Tuesday night, with a slight chance of showers and thunderstorms after 3 a.m. Wednesday, Aug. 19. The chance of precipitation is about 20%, and any new rainfall should be light.

Wednesday Brings The Week's First Weather Hiccup

Scattered showers and thunderstorms are likely Wednesday, with a high near 77. The National Weather Service Cleveland office says rain may arrive early as a cold front moves in, with lingering showers possible into Wednesday night.

The severe-weather threat is currently low, though a few stronger wind gusts of 30 to 40 mph cannot be ruled out. No watches, warnings or advisories are in effect for the Cleveland area.

Lakefront Plans May Get Bumpier Wednesday

Southwest winds are expected to strengthen to around 15 mph Tuesday night and Wednesday morning, with waves building to 2 to 3 feet in the nearshore waters of the central and eastern Lake Erie basin. Anyone heading to the shoreline should keep an eye on updated marine conditions, although no Small Craft Advisory or beach hazard statement has been issued.

Dry Thursday And Friday, Wetter Weekend

Conditions improve Thursday, when skies turn mostly sunny, and the high reaches 78, followed by a sunny Friday near 80. The quiet spell looks brief: Saturday brings a 40% chance of showers and thunderstorms, with the most widespread activity currently favored from late afternoon into evening.

Showers and thunderstorms remain possible Saturday night and Sunday, when the high is expected to stay around 75. Monday looks mostly sunny with only a slight chance of rain before 2 p.m., giving the weekend weather a chance to finally stop freelancing.
