AREAS AFFECTED...NE MS...NW AL...MIDDLE TN

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 031004Z - 031100Z

A WIND DAMAGE THREAT WILL LIKELY CONTINUE EWD INTO MIDDLE TN AND NW
AL EARLY THIS MORNING. ALTHOUGH THE INTENSITY OF THE LINE WILL
CONTINUE TO BE CLOSELY MONITORED...THE WIND DAMAGE THREAT IS
EXPECTED TO BE TOO ISOLATED TO WARRANT WW ISSUANCE.

A SQUALL-LINE CURRENTLY LOCATED FROM WRN TN SSWWD TO NEAR TUPELO MS
AND INTO CNTRL MS IS LOCATED ALONG THE LEADING EDGE OF LARGE-SCALE
ASCENT ASSOCIATED WITH A SHORTWAVE TROUGH OVER THE ARKLATEX. WATER
VAPOR IMAGERY SHOWS AN ENHANCED DRY SLOT MOVING QUICKLY EWD ACROSS
SRN AR AND NE LA WHICH IS ALSO CO-LOCATED WITH A LOW-LEVEL JET JUST
BEHIND THE LINE. THIS REAR-INFLOW JET IS AIDING STORM ORGANIZATION
AND THE LINE IS EXPECTED TO CONTINUE EWD ACROSS NW AL OVER THE NEXT
FEW HOURS. THE LATEST WSR-88D VWPS FROM JACKSON AND BIRMINGHAM SHOW
40 TO 50 KT JUST ABOVE THE SFC WHICH COMBINED WITH A FORWARD MOTION
OF THE LINE AROUND 40 KT SHOULD CONTINUE TO SUPPORT A WIND DAMAGE
THREAT. THE WIND DAMAGE THREAT SHOULD BE GREATEST WITH BOWING
LINE-SEGMENTS. THE SQUALL-LINE IS WORKING OFF OF VERY LIMITED
INSTABILITY SUGGESTING ANY SEVERE THREAT WILL REMAIN ISOLATED AND WW
ISSUANCE IS NOT EXPECTED.
