Thick heat and humidity in place from the nation's midsection to the Southeast will provide fuel for some more drenching thunderstorms today.
As a few potent upper-level disturbances pass through the heat, some of the storms could turn severe, especially across the lower Missouri and mid-Mississippi valleys, as well as a portion of the South.
Kansas City and St. Louis, Mo., Paducah, Ky., and Macon, Ga., are among the cities at higher risk for a gusty storm versus the rest of the Midwest and South, where scattered storms will be common.

Any tornado warning must be taken seriously and those warned should seek safe shelter regardless of whether a tornado is actually confirmed with the warning.
