What is a heatwave?

A heatwave is at least three consecutive days in the 90s or hotter in Ohio. This is a period of excessively hot weather with dangerously hot temperatures and humdity.

Understanding heatwave criteria is essential for preparedness and response efforts. Stay informed, stay cool, and stay safe during this heatwave.

Our weather pattern

A large area of high pressure set up over the entire eastern half of the country as the jet stream also moves northward. This allows for a huge heat dome to develop. 

We won't see the heat dome weaken for a while. Expect our temperatures to remain above average for the next 7 to 10 days.
