Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0629 PM CST Wed Dec 23 2020
Valid 240100Z - 241200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE LOWER
MISSISSIPPI VALLEY AND CENTRAL GULF COAST...
...SUMMARY...
A threat for damaging wind gusts and a few tornadoes will shift
eastward across the Lower Mississippi Valley and central Gulf Coast
region tonight.
...01z Update...
Mid-level heights will fall significantly across the lower MS during
the overnight hours ahead of a short-wave trough that is digging
southeast across the Plains. Surface front associated with this
feature is surging toward the western Gulf States and currently
extends from central AR - northwest LA - southeast TX. Scattered
convection is slowly organizing along the surging cold front and a
squall line is expected to mature over LA later this evening, then
progress east along the central Gulf Coast. Greatest buoyancy at
24/00z extended across southeast TX into western LA and this should
aid convective development over the next few hours.
