Update (3 PM Wednesday): The PDS (particularly dangerous situation) Tornado Watch has been trimmed away from the Baton Rouge area, but it continues in East Louisiana and parts of Alabama and Mississippi until 8 p.m.
A Flash Flood Warning is in effect for Ascension, Assumption, East Baton Rouge, Iberville, Livingston and parishes.
Overview: A strong cold front is headed our way, but it will not clear our area until late Today. Scattered showers and storms, ahead of a main line of storms, are through the day today. A line of storms, or even a broken line of storms, is expected to develop and slowly move through the area throughout the day. This line has slowed down and stalled over portions of South Louisiana and Southwest or South-Central Mississippi, which will lead to an increased flooding risk. These storms will have the potential to turn strong to severe. The severe weather threat will be over by Wednesday evening and the cold front will bring a big cooldown to Southeast Louisiana.
Potential Threats: Damaging wind gusts over 70 miles per hour, heavy rain/flash flooding, and a few tornadoes will be our main concerns, but large hail will also be possible. Some tornadoes may be strong or intense. Heavy rain may lead to flash flooding. Rain totals through Wednesday night may be around 2 to 4 inches with locally higher amounts likely.
Timing: The line will slowly move east during the morning into the afternoon. Rain will begin to clear into the evening/night hours.
How to Prepare: Be sure you have multiple ways to receive weather alerts and ones that will wake you up! Secure any loose holiday and outdoor decorations. Clear storm drains from leaves, debris, and trash. Brush up on your severe weather safety plan – know where your safe place is and be sure it is ready for you, your family, and your pets. Know where to go if you will not be home.
After the Severe Threat: After the cold front passes on Wednesday, temperatures will drop. It will be much cooler on Thursday, but the real winter chill arrives Friday. Temperatures may end up staying below-normal through Christmas, per the Climate Prediction Center.
