...NO SVR TSTM AREAS FORECAST...

...LOWER MS VALLEY...
WATER VAPOR IMAGERY CURRENTLY SHOWS A WELL-DEFINED UPPER-LEVEL
TROUGH IN THE SRN PLAINS WITH STRONG LARGE SCALE ASCENT SPREADING
EWD ACROSS LOWER MS VALLEY. AN MCS IS LOCATED IN LA ALONG THE
LEADING EDGE OF ASCENT. AT THE SFC...A NEARLY STATIONARY FRONT IS
LOCATED JUST OFF THE COAST OF LA. NORTH OF THE BOUNDARY...DEWPOINTS
IN THE LOWER 60S F EXIST OVER SRN LA. THIS COMBINED WITH THE
INCREASING ASCENT WILL LIKELY SUSTAIN THE MCS THROUGH THE EVENING
HOURS WITH WIDESPREAD CONVECTION GRADUALLY MOVING EWD ACROSS SRN MS
INTO SRN AL.

88D VAD WIND PROFILES SHOW IMPRESSIVE SHEAR PROFILES ACROSS SERN LA
WITH 0-6 KM SHEAR VALUES EXCEEDING 50 KT AND STRONG DIRECTIONAL
SHEAR BELOW 3 KM. THIS MAY BE SUFFICIENT FOR AN ISOLATED WIND DAMAGE
THREAT OVER THE NEXT FEW HOURS. HOWEVER...WEAK INSTABILITY AND THE
MARGINALLY STABLE BOUNDARY LAYER SHOULD KEEP ANY THREAT MARGINAL.
THE THREAT SHOULD GRADUALLY DIMINISH AS THE LEADING EDGE OF THE MCS
MOVES EWD OFF THE SERN LA COAST BY 03Z TO 04Z.
