Mesoscale Discussion: Watch Unlikely At This Point as Severe Potential Remains Limited

Mesoscale Discussion 0915
NWS Storm Prediction Center Norman OK
0234 PM CDT Wed May 25 2022

Areas affected…northeast MS into northwest AL

Concerning…Severe potential…Watch unlikely

Valid 251934Z – 252100Z

Probability of Watch Issuance…20 percent

SUMMARY…Gusty winds and a brief spin-up could occur with
convection over the next few hours. However, overall severe
potential is expected to remain limited.

DISCUSSION…A line of convection will continue to shift
east/northeast across northeast MS and northwest AL the next few
hours. This area has destabilized less than areas to the south as
cloud cover has persisted much of the day. Modest effective shear
and poor low and midlevel lapse rates amid weak instability will
limit overall severe potential. While the KGWX VWP does show
somewhat enlarged and favorably curved low-level hodographs, 0-3 km
MLCAPE is fairly weak ahead of the line of convection. Some broad
rotation has occasionally been noted, but weak low-level winds and
modest low-level instability should also limit tornado potential.
Overall, convection has not produced measured severe gusts through
the day, with only minor wind damage reports received. Given the
less favorable downstream environment, severe potential is expected
to remain limited and a watch is not anticipated.
