While the St. Louis area may have some rumbles of thunder, areas to the southeast of the metro area have an increasing risk of stronger storms as you travel toward the Missouri Bootheel and the Ohio River.
A strengthening storm system will move from northeast Texas to western Indiana by late Thursday evening. With the storm passing southeast of the St. Louis area, the warmer, more unstable air conducive to severe weather will stay southeast of the metro area.
Showers and perhaps a few rumbles of thunder will be around Thursday morning. By midday, there should be a brief break while we await the main energy with the system.
