MD 0679 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF EAST TEXAS INTO NORTHERN LOUISIANA



Mesoscale Discussion 0679
NWS Storm Prediction Center Norman OK
0121 AM CDT Sat May 09 2026

Areas affected...Portions of East Texas into northern Louisiana

Concerning...Severe potential...Watch unlikely

Valid 090621Z - 090815Z

Probability of Watch Issuance...20 percent

SUMMARY...Occasional marginally severe storms are possible and could
produce isolated large hail and damaging winds. A watch is not
expected.

DISCUSSION...Convection continues across parts of East
Texas/northern Louisiana. This is being driven by the passing
trough. Lift from this feature should persist a few more hours
before sliding eastward. Steep mid-level lapse rates (7 C/km) were
sampled by the 00Z SHV sounding. This, coupled with modest effective
shear and mid/upper 60s F dewpoints, will foster storms that may
occasionally intensify to severe levels. Isolated large hail and
damaging winds would be possible. The overall threat is expected to
remain disorganized and sporadic.
