MD 0183 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHERN MISSISSIPPI INTO FAR EASTERN LOUISIANA

Mesoscale Discussion 0183
NWS Storm Prediction Center Norman OK
0642 PM CDT Mon Mar 09 2026

Areas affected...southern Mississippi into far eastern Louisiana

Concerning...Severe potential...Watch unlikely 

Valid 092342Z - 100145Z

Probability of Watch Issuance...20 percent

SUMMARY...A storm or two may persist this evening in the short term.
Coverage and longevity of severe potential is not expected to
warrant a watch.

DISCUSSION...Daytime heating and upper 60s F dewpoints have led to
moderate instability over the northern Gulf Coast area with MUCAPE
around 2000 J/kg. While the primary lift is with the wave moving
across northern AL, scattered storms persist extending southwestward
across much of MS and into eastern LA.

The VWP from HDC shows veering winds with height, with 35-40 kt
effective shear, as well as 0-1 km SRH near 100 m2/s2. Given the
uncapped air mass and favorably shaped hodograph, some cells have
exhibited supercell characteristics at times.

As the boundary layer begins to cool this evening, the number and
intensity of cells is expected to decrease. In the short term,
localized hail, a brief tornado or strong gusts cannot be ruled out.
