Strong to severe thunderstorms are possible today near the Gulf Coast as instability increases out ahead of an approaching cold front.
Thunderstorms will fire up this afternoon with the support of an upper-level disturbance, daytime surface heating, and high humidity with dewpoints in the 60s. Short-range computer models show the first thunderstorms firing up over New Orleans between 2-3 PM with the threat clearing the area shortly after Midnight.
The main threat with any strong thunderstorm will be wind gusts to 50 mph and small hail. Any heavy thunderstorm could also contain torrential rainfall, which may lead to ponding on roadways, decreased visibility, and possible flash flooding of poor drainage areas.
Instability will be highest closer to the Gulf of Mexico, along and south of I-10. This places cities such as Morgan City, Houma, and Woodmere at greater risk of severe weather. Travel along I-10 and Route 90 could be especially treacherous during the evening rush hour.
Cooler, drier air will filter into the region behind the system starting tomorrow. For the general election on Tuesday, expect seasonably cool temperatures with afternoon highs in the upper 60s and more comfortable dewpoints near 50 with plenty of sunshine.
