Severe thunderstorms are possible this week from the Central Plains into the Mississippi Valley. The threat for tonight continues across Missouri, Kansas, Oklahoma and Arkansas with an enhanced risk.
Large hail greater than an inch in diameter is the biggest concern for tonight. The threat for wind damage increases late tonight into the overnight. There is a low risk for a tornado, mainly in Oklahoma.
Clusters of storms will be developing this evening, with large hail and an isolated tornado possible. Later tonight, a bowing line of thunderstorms is forecast to push eastward with the potential for damaging winds and very heavy rain.
On Wednesday, the severe weather risk shifts to the east. An enhanced risk extends from St. Louis to the Arklatex, with a slight risk from near Chicago to east of Dallas.
Thunderstorms, some severe, will be pushing ahead of a cold front on Wednesday. As the squall line moves to the east, strong winds is the biggest concern. There may be a few reports of large hail and isolated tornadoes in the late afternoon and early evening.
On Thursday, the dynamics of the front will weaken as upper level energy spins to the north. A marginal risk for severe storms will extend from the Great Lakes to the Gulf of Mexico.
The active weather pattern will continue into this weekend. Another low pressure center will develop back to the west for Friday, returning the severe weather potential to the Central and Southern Plains. The system will shift slowly east to the Arklatex region on Saturday and into the Tennessee Valley and Deep South Sunday.
