MESOSCALE DISCUSSION 1856
NWS STORM PREDICTION CENTER NORMAN OK
0900 AM CST WED NOV 30 2016

AREAS AFFECTED...SOUTHEAST MS/MUCH OF AL/WEST CENTRAL AND
NORTHWESTERN GA

CONCERNING...TORNADO WATCH 511...512

VALID 301500Z - 301700Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 511...512 CONTINUES.

SUMMARY...THE ONGOING LINE OF STORMS EXTENDING FROM EASTERN TN SWWD
TO SOUTHEAST LA WILL CONTINUE MOVING GRADUALLY EASTWARD ALONG WITH
ASSOCIATED/ISOLATED RISK FOR DAMAGING WINDS AND A TORNADO OR TWO.  A
NEW WATCH IS BEING CONSIDERED FOR AREAS EXTENDING EASTWARD ACROSS
PARTS OF AL AND INTO PORTIONS OF WESTERN GA DOWNSTREAM OF THE
EXISTING TORNADO WATCHES.

DISCUSSION...LATEST RADAR LOOP SHOWS THE STRONGEST STORMS WITHIN THE
ONGOING SQUALL LINE ACROSS AL...THROUGH A STRONGLY SHEARED BUT
MINIMALLY UNSTABLE ENVIRONMENT.  MORNING RAOBS DOWNSTREAM OF THE
ONGOING STORMS SHOW AN EVEN WEAKER THERMODYNAMIC ENVIRONMENT...BUT
MODEST HEATING MAY RESULT IN MINIMAL BUT SUFFICIENT CAPE TO SUSTAIN
LOCALLY VIGOROUS UPDRAFTS WITHIN THE BROADER CONVECTIVE BAND.  GIVEN
THE FAVORABLE DEEP-LAYER SHEAR...ANY OF THESE SUSTAINED UPDRAFTS WILL
LIKELY ACQUIRE AT LEAST TRANSIENT ROTATION...ALONG WITH POTENTIAL FOR
LOCALLY ENHANCED WIND GUSTS AND POSSIBLY A TORNADO OR TWO THROUGH
THE MORNING AND INTO THE EARLY AFTERNOON HOURS.  WITH STORMS NEARING
EASTERN PORTION OF THE WATCH AREA ACROSS SOUTH CENTRAL AL...A NEW
WATCH MAY BE NEEDED.
