NWS Jackson, MS wrote its last area forecast discussion before the first event at Apr 21, 8:30 AM CST, 5 hours earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE JACKSON MS 930 AM CDT FRI APR 21 2006 .DISCUSSION... MESOSCALE UPDATE...VERY COMPLEX MESOSCALE SITUATION THIS MORNING...AND NONE OF THE MODELS ARE HANDLING IT WELL. 13Z SFC ANALYSIS SHOWED A MESOLOW OVER SE TX NW OF KPOE...WITH A WELL DEFINED OUTFLOW BOUNDARY EXTENDING ENE FROM IT ALONG A WISNER LA...TO KJAN...TO MACON LINE. OUTFLOW BOUNDARY IS WELL DEFINED IN VISIBLE SATELLITE IMAGERY...AND KGWX 88D VWP SHOWS IT TO BE 3-4 KFT THICK...SO EXPECT IT TO PLAY A SIGNIFICANT ROLE IN WX INTO THE AFTERNOON. KPOE 88D DATA SHOWS A WELL DEFINED SUPERCELL/BOW ECHO STRUCTURE HAS BEEN INTENSIFYING N OF KPOE. THIS ACTIVITY IS AHEAD OF MESOSCALE CONVECTIVE VORT WHICH SHOWS UP IN WATER VAPOR IMAGERY...AND LEDBETTER TX PROFILER SHOWS 40-50 KT MID LEVEL REAR INFLOW JET PUNCHING INTO MCS WHICH NOT SURPRISINGLY NONE OF THE MODELS SHOW. EXPECT AS THIS SYSTEM PROPAGATES DOWNSTREAM TOWARD SOUTHERN PART OF FORECAST AREA...WILL SEE CONVECTION CONTINUE TO INCREASE AND INTENSIFY. MODIFIED 12Z JAN RAOB SHOWS MLCAPE VALUES AROUND 1300 J/KG EVEN WITH TEMPERATURES ONLY IN MID 70S...SO EVEN WITH WIDESPREAD HIGH CLOUDINESS MOVING IN EXPECT ENOUGH INSTABILITY TO FUEL SEVERE STORMS. RUC MODEL SEEMS TO BE UNDERPLAYING THIS AVAILABLE INSTABILITY BASED ON MODIFIED SOUNDINGS. TIMING PLACES CURRENT STG ACTIVITY OVER LA INTO OUR SW PARISHES BETWEEN 15Z AND 16Z...AND EXPECT ADDITIONAL ACTIVITY TO DEVELOP AHEAD OF IT PARTICULARLY ALONG OUTFLOW BOUNDARY EXTENDING ACROSS CENTRAL SECTIONS. THIS WELL DEFINED BOUNDARY MAY PROVIDE A FOCUS FOR ENHANCED ACTIVITY TODAY. SPC WRF MODEL DOES SEEM TO HAVE SOMEWHAT OF A HANDLE ON CURRENT MCS OVER TX/LA...AND IT SHOWS STRONG INCREASE IN CONVECTION LATE MORNING/EARLY AFTERNOON ACROSS CENTRAL AND SOUTHERN SECTIONS OF AREA...WITH INITIAL MODE APPEARING TO BE SUPERCELLS/BOWING LINE SEGMENTS. THIS SEEMS REASONABLE GIVEN 40-50 KT OF 0-6 KM SHEAR OVER AREA. EVENTUALLY SHOULD SEE CONGLOMERATION INTO MORE OF A SQUALL LINE WHICH SHOULD MOVE ACROSS AREA...WRF SEEMS A BIT SLOW IN MOVING IT ACROSS AREA BASED ON CURRENT TRENDS...AND EXPECT THAT MAIN THREAT OF SVR WX SHOULD COME TO AN END ACROSS THE ENTIRE AREA BY EARLY EVENING. AS FAR AS SEVERE WEATHER TYPE...STEEP MID LEVEL LAPSE RATES...650 TO 500 MB LAPSE RATES LOOK TO BE IN 7-8 DEG RANGE WITH SIGNIFICANT CAPE IN THIS LAYER...WOULD FAVOR SOME QUITE LARGE HAIL IN ADDITION TO WIND DAMAGE. COULD BE SOME SIGNIFICANT REPORTS OF BOTH...PARTICULARLY ACROSS SOUTHERN SECTIONS IF ORGANIZED SUPERCELLS/BOWS CAN MAINTAIN OR DEVELOP OUT OF ACTIVITY CURRENTLY OVER LA AND NEAR CONVECTIVE BOUNDARY ACROSS CENTRAL SECTIONS. AS FAR AS TORNADIC POTENTIAL...LOW LEVEL SHEAR IS RELATIVELY WEAK...BUT COULD BE A BIT MORE RISK IF ANY SUPERCELL DEVELOPS IN VICINITY OF CONVECTIVE BOUNDARY WHERE LOW LEVEL VORTICITY WOULD BE ENHANCED. CURRENT HWO SHOWS LESS OF A THREAT OVER DELTA...AND THIS SEEMS REASONABLE GIVEN DEPTH OF COOLER/MORE STABLE LAYER OVER AREA AND NORTHERN STRATIFORM SIDE OF MCS STREAMING TOWARD THAT AREA. IF ANY RISK DOES EXIST THERE...IT WOULD LIKELY BE FROM ELEVATED HAILERS. && .JAN WATCHES/WARNINGS/ADVISORIES... MS...NONE. LA...NONE. AR...NONE. && 08
