Scattered storms will develop across far eastern Ohio and western PA after 2 PM and gradually move east through the evening. Isolated storms may also develop farther west, but more limited coverage. A few storms could produce damaging winds, and all storms will be capable of frequent lightning and heavy rain.
One more day with temperatures touching 90 is expected today, with the added humidity leading to heat indices in the 95-100 F range. A Heat Advisory is in effect for northern Ohio through 8 PM. It will remain warm and humid Sunday, but temperatures will be noticeably lower as conditions slowly improve.
An Air Quality Advisory has been issued for portions of Northeast Ohio on Saturday for ground level ozone. This advisory is in effect from midnight tonight through midnight Saturday night. Air quality levels will be unhealthy for sensitive groups.
Summer heat will be in full swing this week! Remember to "Look Before You Lock" your vehicle to prevent heat-related deaths. Temperatures inside vehicles will very quickly exceed 100 degrees, creating dangerous conditions for children or animals left in cars.
