NWS Jackson, MS wrote its last area forecast discussion before the first event at May 21, 7:53 PM CST, 17 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON MS 853 PM CDT TUE MAY 21 2013 .UPDATE...FOCUS FOR THE REST OF THIS EVENING AND SOME OF THE OVERNIGHT WILL BE WITH STRONG AND SEVERE STORMS MOVING THROUGH A GOOD PORTION OF THE FORECAST AREA. A LARGE LINE OF STORMS IS JUST ABOUT TO ENTER THE NW PART OF THE CWA AND EXPECTATIONS ARE FOR THIS TO STEADILY PUSH E/SE INTO THE CENTRAL PORTION OF THE CWA BEFORE SHOWING A DECREASING TREND. DRIVING THIS LINE IS A COMPACT UPPER DISTURBANCE WHICH IS OVER SOUTHERN OK AND A LARGE COMPOSITE COLD POOL (OUTFLOW BOUNDARY) WHICH HAS CAUSE QUITE A BIT OF WIND DAMAGE OVER NE TX/NW LA/SW AR. OVER THE PAST HOUR OR TWO...THE OUTFLOW BOUNDARY HAS BECOME BETTER BALANCED WITH THE CONVECTION AND THIS SHOULD PROVE TO SUPPORT A DAMAGING WIND THREAT ACROSS THE WESTERN HALF OF THE CWA BEFORE IT MAY RUN OUT OF STEAM. INSTABILITY IS NOT GREAT (1500 J/KG MLCAPE)...BUT SYSTEM DYNAMICS LOOK TO SUPPORT SVR STORMS THIS EVENING AND A PORTION OF THE OVERNIGHT. AS FOR TIMING...LOOKS LIKE THE LINE COULD BE WITHIN THE NATCHEZ TRACE CORRIDOR BETWEEN 1130 PM AND 130 AM...THEN DIMINISHING EAST OF THAT AFTER 1-2 AM. AS FOR HAZARDS...DAMAGING WINDS WILL BE THE PRIMARY FOCUS WITH A SMALL THREAT FOR SMALL HAIL. THE EARLIER THREAT FOR A FEW TORNADOES HAS DECREASED DUE TO 0-3KM SHEAR VECTORS ORIENTED TO THE NE AND THE LINEAR COMPLEX PROPAGATING TO THE E/SE. A SVR TS WATCH MAY BE ISSUED FOR A PORTION OF THE FOR SOME OF THE NIGHT PERIOD. /CME/ && .AVIATION...TIMING THE RESTRICTIONS WITH THE STORMS WILL BE THE FOCUS TONIGHT. OUTSIDE THAT...VFR CONDITIONS LOOK TO PREVAIL WITH SOME POTENTIAL FOR A PERIOD OF MVFR CEILINGS BETWEEN 11-14Z WED MORNING. NOT SURE IF THERE WILL BE MUCH PRECIP DEVELOPMENT ON WED DUE TO WHAT IMPACTS TO THE ATMOSPHERE HAPPEN FROM THE STORM COMPLEX TONIGHT...THUS WILL NOT MENTION PRECIP RISK FOR THE AFTERNOON TIMEFRAME. /CME/ && .PRELIMINARY POINT TEMPS/POPS...
