Two rounds of storms may be possible.
This type of storm system is tricky, as our computer models have a tough time producing what they could do.
A first round of storms may be possible early in the morning between 7 and 10 a.m., although the more likely timing will be for storms after 4 p.m.
If these storms shift even just 50 miles, that could mean the difference between seeing nothing or getting a severe storm.
Stay weather aware!
