Storms, some severe potential, this weekend, then cooler and drier: Southern MS/AL/LA Weather Forecast – 12/6/23

Looking ahead toward the weekend, we have another chance for showers and storms. And there continues to be an outside shot for severe weather. The Storm Prediction Center has outlined parts of our western area with a Slight Risk for severe weather. That is a “2” on the 1-to-5 scale where “5” is the highest risk for the most significant severe weather.

The interesting thing worth watching is how quikcly the risk for severe weather diminishes. The current model guidnace shows the continued risk for storms across Texas, Louisiana and Arkansas. But as the storms shift into Mississippi the mid-levels of the atmosphere may not be as favorable.

The Euro model this morning shows a few things of note.

First in how clustered the storms appear in the reflectivity estimate. This is a good indicator that we have a chance for discrete storms, but also that there may not be much capping ahead of the line. While that would mean we can see discrete storms, it also means that many storms may go up at once and cluster together. And that could limit the threat for tornadoes (but hold a potential for strong wind gusts).

Second is the blob of storms shown off the Florida coast and out into the Gulf. If that blob is big enough, it would limit the low-level flow into the region and cut off the juice needed for stronger storms to develop.

Third, the mid-level atmospheric setup may have more “speed shear” and less “directional shear” which would limit the tornado risk, but hold the risk for strong wind gusts. And the speed shear may be locked up above a weak inversion that may develop as the storms traverse the area. That would limit the potential for some of the strongest winds from mixing down the surface in some of the storms that develop.

So there is still a bit to chew on and figure out as we move toward the weekend.

Once we get through the storms, things look to cool down as we move through next week. And may stay seasonably cool through all of next week and potentially next weekend, too.
