AREAS AFFECTED...NERN MS...NWRN AL...SRN TN

CONCERNING...TORNADO WATCH 271...

VALID 092355Z - 100130Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 271 CONTINUES.

SUMMARY...STRONG TO SEVERE WINDS WILL REMAIN PROBABLE...ESPECIALLY
WITHIN THE CENTER PORTION OF THE QLCS OVER NERN MS THAT SHOULD
PROGRESS INTO NWRN AL/SRN TN. A TORNADO OR TWO ALSO REMAINS
POSSIBLE.

DISCUSSION...RADAR REFLECTIVITY/VELOCITY SIGNATURES DETECT THE MOST
INTENSE PORTION OF A BROADER QLCS SURGING ACROSS PARTS OF
NERN/E-CNTRL MS. THIS CORRIDOR IS WITHIN THE MOST FAVORABLE
ORIENTATION TO STRONGER 700 MB SWLYS /AROUND 40 KT PER JAN VWP
DATA/. ALTHOUGH DOWNSTREAM AIR MASS IS A BIT COOLER /SURFACE
TEMPERATURES IN THE LOWER 80S/...THE BULGING LINE WILL SUPPORT
STRONG TO EVEN MEASURED SEVERE GUSTS AS IT LIKELY PROPAGATES INTO
NWRN AL AND FAR SRN TN IN THE NEXT COUPLE OF HOURS. GWX VWP DATA
HAVE ALSO SAMPLED AN INCREASE IN 0-1 KM S/SELYS JUST AHEAD OF THE
LINE...WITH SHEAR VALUES TO NEAR 20 KT. THIS WILL SUPPORT A RISK FOR
A TORNADO AS WELL.
