The severe weather threat for Tornado Watch 583 continues.
SUMMARY...A localized corridor of greater tornado potential appears
to be evolving from near Interstate 20 southwest, across far eastern
TX and west-central LA.
DISCUSSION...As of 22:40 UTC, regional radar analysis showed several
supercells reaching maturity ahead of the cold front across portions
of far eastern TX and west-central LA. Likely wider and more robust
as a result of greater storm-relative inflow and forcing near the
frontal band, these updrafts are expected to remain relatively
uninterrupted as they track northeastward toward an analyzed warm
front over the next 1 to 2 hours. Very strong low-level shear
(0-500m SRH 200+ m2/s2) from KPOE VAD and SPC mesoanalysis will
favor strong low-level mesocyclones with an attendant risk for
tornadoes, some of which could be strong.
