Strong to severe thunderstorms are possible Tuesday across South Texas.

A stalled frontal boundary in the region on Tuesday will be the focus for severe weather development. With plentiful moisture and multiple small upper level impulses moving through the area, isolated to scattered thunderstorms look likely, with the potential to become severe. Supercells with the capability of all hazards will be probable. Some flooding could also occur due to heavy rainfall totals from the end of the weekend through Tuesday.
