0142 PM CDT Fri Mar 31 2023
Areas affected...Southwest into central AR
Concerning...Tornado Watch 94...
Valid 311842Z - 312015Z
The severe weather threat for Tornado Watch 94 continues.
SUMMARY...A corridor of strong tornado potential may develop through
mid afternoon as supercells move east-northeastward.
DISCUSSION...At 1830 UTC, scattered supercells have developed from
southwest into central AR, with increasing midlevel rotation noted
with cells immediately west and southwest of Little Rock. Recent
mesoanalyses and the LZK VWP continue to show 0-1 km and effective
SRH in excess of 300 m2/s2, with some stronger heating noted just to
the south of the southernmost cells. With MLCAPE in excess of 1500
J/kg across the region and very favorable wind profiles, tornado
potential is expected to ramp up through mid afternoon. The greatest
threat of a strong tornado is expected over a corridor across
central AR for the next 1-2 hours.
