>Severe storms are developing in Southern Texas into Louisiana. There are actually 2 severe weather situations, but we will focus more on the tornado watch. Below is an image of real-time radar of that watch.
This watch goes until 10:00pm CDT.
This watch has been issued as single-cell storms have developed into a loosely organized cluster. These storms are generating warnings, and below are those warnings.
The low level jet stream is working its magic across the region, giving the atmosphere a kick of instability. That explains the CAPE values of instability have surpassed 3000 j/kg. That means the atmosphere is at a very good degree of instability.
However, it does appear there isn’t much lift within this storm environment.
Vorticity maps indicate that there is negative vorticity, while positive vorticity indicates areas suitable for storm development. Tornadoes are not incredibly likely
But, the Surface Based Lifted Index is at -8, indicating major instability.
