I’m back, and ready to roll! It looks like we are headed right back into another severe threat on Tuesday. Preliminary reports show 22 tornadoes touched down yesterday from northeast Louisiana, through a big chunk of Mississippi. Locally, we dodged the worst, and had some solid rainbows. Win win. Tomorrow is a pretty interesting day. Definitely a garage the cars day.
Storms should be in progress over northeast Texas and northwest Louisiana by early to mid morning Tuesday. As these early storms move this way, they will hit some very unstable air. Instability is a key ingredient for severe weather, and when it’s on the high end like this, and the freezing levels are low enough, we get the threat for isolated damaging hail. SPC has outlined our area with a 10% risk of 2 inch or larger, diameter hail. That most definitely can leave several marks. Hail typically remains pretty isolated, so it’s likely you won’t see it. But if you find yourself under a warning, garage that car if possible. I think damaging wind is the secondary threat, and while an isolated tornado is possible, I’d think the higher risk of that is northeast of us. You can also see in the SPC risk map, that we are in a level 3/5, enhanced risk. The enhanced risk is generally from Alexandria, to the east and northeast, and this is where the highest chance of severe weather will be.
The good news is, after this, we should quiet down for a good bit. I’ll update things this evening.
