Heat and humidity will continue to build Tuesday and Wednesday. Temperatures will warm into the low to mid 90s, with afternoon heat indices peaking in the upper 90s to low 100s. Far Northeast Ohio and Northwest PA may stay slightly cooler where coverage of showers and storms will be greater.
A persistent heat dome will remain in place this week, with temperatures warming into the mid-90s and heat indices in the low 100s. Remain in air-conditioned spaces as much as possible, drink plenty of water and fluids throughout the day, wear loose-fitting, lightweight, and light-colored clothing, and avoid high-energy activities, strenuous outdoor work, or exercising during the hottest hours. Don't forget to check on family members, older adults, neighbors, and people without reliable cooling, and NEVER leave children or pets alone in a hot vehicle.
