Heavy rain/localized flooding possible: Here's what you need to know

A weak front remains stalled across the state this morning. Meanwhile an upper-level piece of energy is rotating around the base of a larger upper-level trough aloft. This is creating lift in the atmosphere and giving it a boost through today. For that reason, I believe the heaviest rain will fall today and rain coverage will be highest today.

Later today, a surface low pressure will develop along this front, moving northeastward across the state. This will locally enhance rain through this afternoon and evening. Based off of current model analysis, I believe the heaviest rainfall will be closer to I-10, where an additional 2-6 inches of rain could be possible through tomorrow.

This could lead to localized flooding, especially with storms producing high rainfall rates and training over some of the same areas. Across central Louisiana, rain totals through tomorrow night, should be closer to 1-3 inches.

A slight severe weather threat could be in the mix as the weak surface low causes winds to veer (turn southerly) at the surface. Instability profiles are rather weak, so the threat for severe weather looks rather low. Biggest threat would be damaging winds.

Best thing to do for today is to monitor the radar throughout the day. You can download the KALB Weather app, so that you can have radar on the go. Be prepared for the possibility of Flash Flood warnings, especially for areas further south. Otherwise, continue with your daily activities.
