Flash flood warning active through Monday evening in Northeast Ohio
CLEVELAND, Ohio (Monday, July 1, 2025, 6:30 p.m. ET) — The National Weather Service issued a Flash Flood Warning for Geauga, Portage, and Summit counties, in effect until 9:15 p.m. this evening. A Flood Advisory was also issued for Cuyahoga, Geauga, Medina, Portage, and Summit counties through 8:15 p.m.
Scattered thunderstorms and bursts of heavy rain are expected to continue across Northeast Ohio through the evening hours. Some of these storms are producing downpours intense enough to cause roadway flooding and localized ponding, particularly in urban areas and low-lying roads. A few storms may also bring gusty winds, although severe wind damage is not expected at this time.
The atmosphere remains very humid, and with temperatures lingering in the upper 70s to low 80s Fahrenheit (around 26–28 °C), conditions will stay muggy into the night.
Overnight, thunderstorm activity will gradually diminish, and skies will begin to dry out. However, humidity levels will stay elevated, and temperatures overnight will hold near 70 °F (21 °C). A cold front will approach the region late tonight into early Tuesday, pushing out the lingering moisture.
Light showers may persist Tuesday morning, primarily across southern portions of Northeast Ohio, but dry air will begin to take over by midday, clearing skies gradually from west to east across the region. Afternoon sunshine will make a return for much of Tuesday.
Wednesday and Thursday will bring a pleasant break from the sticky weather. Daytime highs are forecast to reach the low 80s °F (27–28 °C), with lower humidity providing some relief. Another weak cold front is expected to slide across the area on Thursday, introducing a slight risk of scattered showers, particularly in the afternoon and evening.
Friday appears warmer yet more comfortable, setting up a very warm pattern heading into the Independence Day holiday weekend. The chance for rain increases toward Sunday, especially late in the day, as humidity builds again.
Stay alert for updated watches and warnings, particularly in low-lying and flood-prone regions of Northeast Ohio.
