The National Weather Service says storms will intensify this evening, with the highest tornado potential coming between 5 and 11 p.m. in Central and Southwest Oklahoma.
A Tornado Watch has been issued until 11:00 p.m. for Central and Eastern Oklahoma. The counties included roughly follow the Interstate 44 corridor.
There are still questions about the exact timing of the storms, but the Norman Forecast Office advises residents to not leave work or school this afternoon without checking the weather first.
The region under a moderate risk for severe weather includes the Oklahoma City area, Enid, Ponca City, Stillwater, Ada, Ardmore and Durant. Northwest Oklahoma is under a slight risk for severe weather.
Forecasters say supercells could develop in the area, creating tornadoes. Baseball-sized hail is also possible with the storms along with winds of up to 70 mph.
After the system moves through, unseasonably cold weather is expected. A freeze watch is in place until late Thursday morning for counties in the Panhandle.
