Areas affected...Far eastern Arkansas...Northern Mississippi and
Alabama...into southern Tennessee.

Concerning...Tornado Watch 32...

Valid 172309Z - 180015Z

The severe weather threat for Tornado Watch 32 continues.

SUMMARY...A replacement tornado watch for the northwestern half of
Tornado watch #32 will be coordinated shortly.

DISCUSSION...Numerous thunderstorms including semi discrete
supercells are ongoing across the area. Strong low-level shear
(450-500 0-1km SRH)  sampled from the MEG VWP suggests the tornado
threat is likely to continue after the 00z expiration time of WW32.
Expansive convective coverage into north-central Alabama may
somewhat impact buoyancy near the diffuse warm front across southern
Tennessee. However, additional thunderstorm development across far
eastern Arkansas may support the severe threat well into the night
across north-central Alabama. A new tornado watch will be
coordinated shortly.
