MD 0756 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR SOUTH-CENTRAL LOUISIANA
Mesoscale Discussion 0756
NWS Storm Prediction Center Norman OK
0327 PM CDT Wed May 10 2023
Areas affected...south-central Louisiana
Concerning...Severe potential...Watch unlikely
Valid 102027Z - 102200Z
Probability of Watch Issuance...5 percent
SUMMARY...Cannot rule out a tornado this afternoon/evening across
south-central Louisiana.
DISCUSSION...Several transient supercell structures have translated
across the Gulf Coast of Louisiana today. In the last few hours 0-1
km SRH has increased to over 300 m2/s2 per LCH VWP. This may
increase further into the evening as a MCV over the Gulf lifts
northward. Thus far, low-level circulations have been quite weak,
likely due to weak low-level flow. However, if some stronger
low-level flow develops as this MCV approaches the coast, the
tornado threat could increase.
Given the isolated/marginal threat, a watch is unlikely.
