Areas affected...Far Northern Alabama

Concerning...Tornado Watch 305...

Valid 202247Z - 210045Z

The severe weather threat for Tornado Watch 305 continues.

SUMMARY...A threat for tornadoes, very large hail and wind damage
will continue over the next couple of hours across far northern
Alabama.

DISCUSSION...The latest hi-resolution radar imagery from Huntsville,
shows two intense supercells across far northern Alabama. These
storms are located near an axis of moderate instability, where the
RAP has MLCAPE around 2500 J/kg. The latest WSR-88D VWP in the
vicinity of the storms has 0-6 km shear of 45 to 50 knots, 0-3 km storm-relative helicity near 200 m2/s2, and a curved hodograph. This environment will continue to support intense supercell development.
A tornado will be possible over the next hour, especially as these
two supercells interact with each other. The supercells could also
produce very large hail and wind damage.
