Active weather moved into the eastern third of the country Wednesday.

This precipitation preceded a cold front that stretched from the Plains through the Ohio Valley. Deep moisture streamed northward from the Gulf of Mexico, instigating widespread showers and thunderstorms through the Southeast and Ohio Valley. While the thunderstorms in the Southeast were fairly typical for summer, thunderstorms in Ohio were quite strong and produced heavy rain.

These Ohio Valley storms also prompted severe thunderstorm warnings and tornado warnings from intense thunderstorms that rolled through populated areas in Ohio. There were no reports of tornadoes as of mid-afternoon Wednesday, but damaging wind and large hail were widespread from Indiana through northern Ohio.

Meanwhile, monsoon moisture in the Southwest produced scattered showers and thunderstorms in Arizona, New Mexico, and Colorado. These thunderstorms may be particularly dangerous due to the possibility of starting wildfires.

Temperatures in the Northeast rose into the 70s and 80s, while the Southeast saw temperatures in the 80s and 90s. The Southern Plains rose into the 90s and 100s, while the Southwest saw similar temperatures.
