Tornadic thunderstorms are likely this afternoon and especially this evening across the eastern Texas panhandle, western Oklahoma and southwest Kansas. Extreme helicity values will exist after sunset, which will increase the potential for any tornadoes that do form to be strong.

The Storm Prediction Center has outlined this area as a Moderate Risk, with a 15% tornado probablity in the latest outlook. Extremely large hail will also be possible with these storms, as indicated by the 45% "hatched" area.

A slight risk extends all the way to the Great Lakes!

This is a developing, potentialy dangerous weather situation for people in the Moderate Risk area! We'll likely have the highest number of streamers to date in the field, so be sure to follow the Live Tracker and check back for updates as we expect to update the blog again as storms fire.
