AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE JACKSON MS
1045 AM CST SUN DEC 4 2005

.DISCUSSION...NO REAL CHANGING IN THINKING. AS FRONT HAS ALL BUT
STALLED AROUND THE I 20 CORRIDOR. SOUTH OF THE FRONT TEMPS HAVE
WARMED UP NICELY TO THE LOWER AND MID 70S. THE JACKSON EVERS
INTERNATIONAL AIRPORT EVEN WARMED BACK UP TO 70 AROUND 820 AM JUST
BEFORE THE FRONT PASSED. ISENTROPIC LIFT ALREADY STARTING TO
INCREASE AND THE SHRA AND EMBEDDED TSRA ACTIVITY IS RESPONDING
ESPECIALLY ACROSS THE NRTHN MS AND SESTRN AR. FULLY EXPECT THIS TO
INCREASE WITH GOOD COVERAGE NORTH OF THE FRONT. SOUTH OF THE FRONT
THERE STILL LIES SOME SEVERE POTENTIAL. VERY WARM AND HUMID
CONDITIONS(70 DEGREE TEMPS OVER MID 60S DEWPOINTS) FOR THIS TIME OF
THE YEAR IS LEADING TO A DECENTLY UNSTABLE ATMOSPHERE AND WITH THE
DEVELOPMENT OF A SFC WAVE IN SE TX SHRA AND TSRA ARE EXPECTED TO
INCREASE IN THE WARM SECTOR. THERE EXIST ENOUGH SHEAR FOR A FEW
STORMS TO BECOME SEVERE AND SPC HAS MENTIONED THAT A WATCH MAY BE
NEEDED LATER TODAY FOR OUR STHRN COUNTIES. THE MAIN THREAT WILL BE
HAIL AND WINDS. WILL HOLD OFF ON AN UPDATE RIGHT NOW.

&&

.AVIATION...WIDESPREAD MVFR CEILINGS WILL CONTINUE TO PREVAIL MOST
OF THE DAY SOUTH(MEI/HBG) OF THE FRONT WHILE AREAS
NORTH(JAN/GLH/GWO) MAY DROP TO IFR STATUS AT TIMES. LOOK FOR SHRA
AND TSRA ACTIVITY TO INCREASE THROUGHOUT THE DAY ESPECIALLY AROUND
THE GLH/GWO/JAN/MEI. HBG MAY HOLD OFF UNTIL LATE THIS AFTERNOON
BEFORE ACTIVITY REALLY GETS GOING. SHRA AND TSRA WILL CAUSE BOTH THE
VISBIES AND CEILINGS TO DROP TO IFR STATUS AT TIMES. THERE IS ALSO
THE THREAT OF GR AT ALL SITES BUT ESPECIALLY NEAR MEI/HBG. TSRA
WINDS MAY ALSO BECOME A PROBLEM NEAR THOSE 2 SITES AS WELL.
