Areas affected...west-central Arkansas

Concerning...Tornado Watch 144...146...

Valid 260149Z - 260345Z

The severe weather threat for Tornado Watch 144, 146 continues.

SUMMARY...Severe threat continues within WW146.

DISCUSSION...Supercells continue to move across west-central
Arkansas, producing reports of 1.5-2.5 inch hail. The environment
ahead of these storms continues to be strongly unstable with ample
shear for organization. This will likely continue to support
potential for large to very large hail (some 2+ inches in diameter).
Storms have remained mostly elevated but should a cell be able to
move into the warmer air to the south and become surface based in
the more backed southeasterly flow, potential for a tornado would be
possible.
