A line of heavy thunderstorms is marching across South Louisiana, bringing us a threat of severe weather. A tornado watch has been issued until 3 a.m. and there is the potential for strong, damaging winds and local flooding rainfall.
The greatest threat appears to arrive between 10 p.m. and 1 a.m. Some showers will linger into the morning drive, and it will be much cooler. Highs on Wednesday will not get out of the 60s after today's lower-80s. A dry spell sets up for the rest of the week with a cooling trend coming over the weekend.
