Mesoscale Discussion 0043
NWS Storm Prediction Center Norman OK
0853 AM CST Sat Jan 24 2026
Areas affected...northeast TX...southern AR...northern LA...western
MS
Concerning...Winter mixed precipitation
Valid 241453Z - 242000Z
SUMMARY...Moderate to heavy freezing rain and sleet are expected to
persist across the Ark-La-Tex to Ark-La-Miss regions into early
afternoon. Liquid-equivalent precipitation rates of a tenth to
quarter-inch per hour should be common, locally up to a half-inch
per hour.
DISCUSSION...A swath of moderate to heavy mixed precipitation is
ongoing across east TX and the Ark-La-Tex. Surface observations
confirm hourly precipitation rates of .10-.25 in/hr are common, up
to around .50 in/hr. 12Z guidance is rather consistent in indicating
this swath of precip persisting through at least early afternoon,
gradually shifting east-northeast amid rather pronounced low-level
warm theta-e advection. A classic freezing rain to sleet sounding
was sampled at 12Z in SHV. This type of thermodynamic profile should
continue to steadily push southward in northern LA. Farther east,
the surface freezing line should only drift to nearly stall across
western MS into the early afternoon.
