The northeast corner of Colorado, particularly Logan, Phillips and Sedgwick counties, is at the greatest risk of seeing hail up to two inches in diameter, wind gusts up to 80 miles per hour, and even a few tornadoes.

While the greatest risk is expected between 5:00 and 7:00 p.m., the watch is set to remain in effect until 10:00 p.m.

In southeast Colorado, as well as parts of New Mexico, Texas, Oklahoma and Kansas, a watch is not expected to be issued. However, a few strong storms are possible through the early evening, with isolated strong wind gusts the primary concern.
