Areas affected...northern Mississippi

Concerning...Tornado Watch 97...99...

Valid 010323Z - 010530Z

The severe weather threat for Tornado Watch 97, 99 continues.

SUMMARY...Severe risk continues. Tornado environment is becoming
more favorable across northern Mississippi.

DISCUSSION...A broken line of storms moving across the
Arkansas/Mississippi border is tracking eastward into an environment
becoming favorable for strong tornadoes. VAD profiles from DGX
(Brandon, MS) and GWX (Columbus Air Force Base) show low-level shear
has increased to around 400-700 m2/s2 as the nocturnal low-level jet
has strengthened. Surface objective analysis indicates SBCAPE around
1000-1500 J/kg ahead of the advancing line of storms. Expect the
storms moving in from the west to organize with increasing threat of
strong tornadoes over the next few hours.
