218 PM CST THU NOV 29 2001

SHOWERS AND THUNDERSTORMS FINALLY MOVING ACROSS OUR WESTERN ZONES AS
OF THIS WRITING.  STILL WAITING FOR THE STRONG TO SEVERE WEATHER TO
GET GOING, BUT EXPECT IT SOON.  VORT MAX IS CURRENTLY OVER
NORTHWESTERN LA, AND THIS WILL TRACK NORTHEASTWARD ACROSS WESTERN
TENNESSEE.

SOUNDINGS STILL SHOWING A MID LEVEL CAP, BUT LARGE SCALE ASCENT OUT
AHEAD OF THE FRONT SHOULD BE ENOUGH TO ERODE THIS SOMEWHAT.  WITH
MSAS LI VALUES RANGING FROM 0 TO -3 OUT AHEAD OF THE FRONT, AND WITH
LOW LEVEL JET STILL FORECAST OVER CENTRAL ALABAMA THIS EVENING, ALONG
WITH STRONG UPPER LEVEL JET STREAK, STILL EXPECT SEVERE OVER MUCH OF
THE STATE.

SPC HAS MODERATE RISK OVER OUR AREA, AND WILL CONTINUE WITH DAMAGING
WIND AND HEAVY RAIN POTENTIAL WORDING IN THE ZONES.

EXPECT FRONT TO BE OVER CENTRAL ALABAMA BY 00Z, AND IT SHOULD BE
EXITING THE STATE BY 06Z.

WILL LET CURRENT FLOOD WATCH EXPIRE.  RAINFALL HAS NOT BEEN AS HEAVY
AS PREVIOUSLY FORECASTED OVER CURRENT WATCH AREA, AND WITH FRONT
SPEEDING UP, RAINFALL SHOULD ALSO BE SPEEDING UP AND EXITING THE
NORTHWESTERN PORTIONS OF THE STATE EARLY THIS EVENING.  MUCH OF
THE RAIN THIS EVENING WILL BE FALLING OVER AREAS OF CENTRAL AND
EASTERN ALABAMA THAT HAVE NOT RECEIVED MUCH RAIN.

THE FINAL WORRY THIS EVENING DEALS WITH WIND ADVISORY ACROSS THE
NORTHERN COUNTIES.  RIGHT NOW, OBSERVATIONS SHOWING SUSTAINED WINDS
REMAINING JUST BELOW ADVISORY CRITERIA.  PLAN ON HOLDING OFF RIGHT
NOW, BUT THIS WILL NEED TO BE MONITORED.
