Cleveland weather forecast for Friday, July 18, 2025. Attention then turns toward our next storm system that will be approaching late Saturday into Saturday night. We'll enjoy sunshine and increasing humidity Saturday with highs in the mid 80s. A line of strong to severe storms will break out in the western Great Lakes Saturday and we'll be watching this line of storms roll into northern Ohio later Saturday, we're thinking evening at this point. These storms could pack a punch depending on how they hold together, but damaging winds would be our primary threat in addition to heavy rain and lightning. Shower chances will linger with cloud cover to get our Sunday started. Much like today, the showers would give way to sunshine later in the day with another round of more comfortable air moving into northern Ohio. Highs Sunday return to the 70s. The heat looks to return next week with highs surging back into the upper 80s and low 90s Wednesday and Thursday. If the hot temps weren't enough, we'll have some of our highest humidity of the year so far sending heat indices into the 100 degree range. Here is your Cleveland weather forecast: SATURDAY: Sunshine and becoming more humid. PM storms roll in--some could be strong. Mid 80s. SUNDAY: Leftover clouds and showers early then clearing skies. Mid to upper 70s. READ MORE: https://www.wkyc.com/article/weather/... At 3News, we’re here to share your voice and tell your story.
