Areas affected...northeastern Louisiana...southeastern
Arkansas...and west-central Mississippi
Concerning...Severe potential...Watch possible
Valid 092324Z - 100100Z
Probability of Watch Issuance...40 percent
SUMMARY...Storms continue to gradually increase across the
west-central Mississippi Vicinity. Additional storm development may
require WW issuance to be considered.
DISCUSSION...Latest radar loop shows convection gradually increasing
in coverage and intensity across the west-central Mississippi
vicinity, in the vicinity of a west-to-east baroclinic zone. Though
broad-scale ascent remains weak, the thermodynamic environment
(characterized by 4000 to 5000 J/kg mixed-layer CAPE) remains
strongly favorable for intense convection. Given enhanced mid-level
westerlies contributing to favorable shear for organized storms,
conditional severe-weather potential may be realized across this
region over the next few hours. We will continue to monitor
convective evolution, with additional development potentially
requiring consideration of new WW issuance, or extension of
existing/nearby watches.
