Severe Weather in September Over the Plains, Midwest
Nasty storms will target the northern Plains tonight.
The danger of severe weather will shift eastward across the Plains into Friday, before expanding over the Mississippi Valley Friday night. Meanwhile, the remnants of Hermine will cause trouble over the lower Mississippi Valley tonight.
The first round of violent thunderstorms will target the northern and central High Plains during the first part of tonight shifting from eastern Wyoming to the western part of the Dakotas and Nebraska Panhandle.
The thunderstorms can bring isolated damaging winds, hail and flash flooding. A couple of tornadoes may also touch down in the strongest storms.
The severe weather danger will re-emerge farther to the east Friday afternoon, stretching from Oklahoma City, Okla. to Kansas City, Mo. and Des Moines, Iowa.
Look for this area to grow in size as it shifts eastward into the heart of the Mississippi Valley Friday night, as the storm from the Rockies and Tropical Rainstorm Hermine try to join forces.
We will have more on this during the day Friday. Check in at AccuWeather.com for updates.
Farther east tonight, Hermine, now a tropical rainstorm, will continue to generate locally violent thunderstorms on its southern and eastern flank.
Thunderstorms capable of producing damaging wind gusts, flash flooding and even a few tornadoes will stretch from northeastern Texas to the tri-state area of Illinois, Indiana and Kentucky. The storms will tend to diminish late in the evening.

The "Dead of Winter," the one-month period when normal temperatures reach their lowest levels, has come to an end for much of the United States. Some people may find it odd that the "Dead of Winter" does not encompass the darkest day of the year (the first day of winter). That is due to a seasonal lag in temperatures. More heat continues to be lost than is gained from the start of winter until this time of year.
