Areas affected...Central MS

Concerning...Severe potential...Watch unlikely 

Valid 270624Z - 270800Z

Probability of Watch Issuance...20 percent

SUMMARY...A tornado or two and locally damaging winds will remain
possible through about 09Z, with environment expected to become less
favorable later this morning.

DISCUSSION...Supercell embedded within a small thunderstorm cluster
just southeast of Jackson intensified and produced a TDS in southern
Rankin county. This intensification appeared to occur coincident
with the northeast extent of near 70 surface dew points overlapping
the southern periphery of 1-km AGL southwesterlies in excess of 55
kt. The threat for an additional tornado or two might persist for a
few more hours with this cluster. The broader expectation is for the
environment to become less favorable for sustaining supercell
structures as the southern periphery of the strong low-level jet
shifts east and flow becomes increasingly veered, especially after
09Z. This will likely result in increasing separation of enlarged
low-level hodographs from the plume of modest buoyancy centered
farther west/southwest on the Sabine Valley.
