April 30: Tonight's Thunderstorm Forecast

The image above is for 9:00 pm CDT tonight. At 9pm, we expect storms to gradually develop in West Tennessee and into Arkansas. This will be due to a cold front pulled by a low pressure system in Canada. The cold front will also initiate some weaker storms in Wisconsin into Illinois.
Looking ahead to 11:00pm CDT tonight, the storms will increase in Wisconsin and a bit more into Illinois. More interestingly, there will be stronger storms in West Tennessee and West Kentucky. The storms will also increase in coverage in Arkansas. Some spotty showers are possible into Texas as well.
The above image is valid at 2am CDT. As the cold front continues to move east, the storms will increase in coverage and strength, especially in the Northern portion. The best probability of storms will be in West Tennessee and West Kentucky. Probabilities will reach up to 90% in the Michigan area into Indiana. Spotty storms will be possible into Texas.
