Mesoscale Discussion 0717

1114 AM CDT Tue May 06 2025

Areas affected...southern Louisiana

Concerning...Severe potential...Watch possible 

Valid 061614Z - 061745Z

Probability of Watch Issuance...60 percent

SUMMARY...There is an increasing supercell threat across southern
Louisiana with a threat for large hail and perhaps a tornado.

DISCUSSION...Scattered cloud cover has supported rapid
destabilization south of a northward moving warm front across
southern Louisiana. A strengthening low-level jet across southern
Louisiana (45-50 knots per LCH VWP) has provided sufficient forcing
for convective development late this morning. These storms which
have developed have quickly shown supercellular characteristics amid
40 knots of effective shear (per LCH VWP). While a tornado threat
cannot be ruled out, storm propagation across the warm front should
mostly support a hail threat from this activity. 

Due to the propagation across the front and displacement well east
of the upper-level forcing, duration of the threat and necessity for
a severe thunderstorm watch remains unclear.
