After a very active night with part 1 of severe weather, we start this Monday with scattered showers and a few thunderstorms. Otherwise, it is mostly cloudy and mild with temperatures in the 60s.
A warm front will move northward from the Louisiana Coast through Baton Rouge and into Mississippi by the early afternoon, and this will be part 2 of severe weather. This will allow very warm and humid air to come up from the Gulf of Mexico, and it will be breezy. This will also make the atmosphere very unstable. Scattered to numerous showers and thunderstorms will continue to develop all afternoon. Some of them are expected to be strong to severe at times. SPC has put all of Louisiana in a Slight Risk for severe weather today. The threats will be large hail, damaging winds and a few tornadoes. We will also have more heavy rain across Southeast Louisiana. A Flash Flood Watch remain in effect for parts of the area. Some areas picked up 2-3" of rain overnight and there is some flooding already occurring. High temperatures will be in the mid to upper 70s.
The showers and storms will continue this evening ahead and along a squall-line that will move into Baton Rouge. This line will be associated with a cold front, and this will be part 3 of the severe weather. These storms could also be severe at times with damaging winds and a few tornadoes. Temperatures will remain in the 70s.
Once the cold front moves through this evening the storms will come to an end. We will have partly to mostly cloudy skies with a few sprinkles overnight. It will turn much cooler with lows in the lower 40s.
