ksstormhunter Posted March 9, 2011 Share Posted March 9, 2011 Just updated latest severe weather threat map, still seeing the highest potential for tornadic development in Central part of Louisiana. RUC showing SFC Based Capes still running over a 1000 (J/kg) in this area, coupled with SFC LI's holding around -6, and MLCAPES still running between 50-75. Also starting to see increased instability and potential across MS areas. Link to comment Share on other sites More sharing options...

SmokeEater Posted March 9, 2011 Share Posted March 9, 2011 Multiple tornadic circulations, with a major one crossing the LA/MS state line. Tony I think it was you that said this was going to be a 3am to 10amish event. Great call. Link to comment Share on other sites More sharing options...
SmokeEater Posted March 9, 2011 Share Posted March 9, 2011 MESOSCALE DISCUSSION 0211 NWS STORM PREDICTION CENTER NORMAN OK 0439 AM CST WED MAR 09 2011 AREAS AFFECTED...SERN LA/SERN MS CONCERNING...TORNADO WATCH 45... VALID 091039Z - 091145Z THE SEVERE WEATHER THREAT FOR TORNADO WATCH 45 CONTINUES. THE THREAT FOR TORNADO-PRODUCING SUPERCELLS IS INCREASING ACROSS PORTIONS OF SERN LA AND SERN MS. TORNADO WATCH 45 HAS BEEN EXPANDED SWD TO INCLUDE THE REMAINDER OF SERN LA. A SQUALL LINE EXTENDING FROM NEAR MEI TO 30 MILES WEST OF PIB TO 35 MILES SSW OF HEZ CONTINUES ADVANCING E-SEWD WITH AN ATTENDANT THREAT FOR DAMAGING WINDS AND ISOLATED TORNADOES. MEANWHILE...RECENT RADAR IMAGERY HAS INDICATED AN UPWARD TREND IN SEMI-DISCRETE CONVECTION OVER SERN LA AND SERN MS AHEAD OF THE SQUALL LINE. THIS ACTIVITY IS IN RESPONSE TO INCREASING ASCENT IN ASSOCIATION WITH A SUBTLE MID-LEVEL SHORTWAVE TROUGH SWINGING THROUGH THE NWRN GULF OF MEXICO AND SRN LA. THE ASCENT IS BEING AUGMENTED BY INCREASING LOW-LEVEL CONVERGENCE WITHIN THE EXIT REGION OF A 50-55-KT 850-MB JET NOSING INTO SRN LA PER RUC ANALYSIS. AS SUCH...SEMI-DISCRETE CONVECTION IS FORECAST TO CONTINUE TO EVOLVE OVER SERN LA AND STREAM NEWD INTO SERN MS EARLY THIS MORNING. RUC ANALYSIS INDICATES SBCAPE VALUES ON THE ORDER OF 500-1000 J/KG OVER THE DISCUSSION AREA...WITH LITTLE IN THE WAY OF CONVECTIVE INHIBITION...ALLOWING CONVECTION TO BECOME ROOTED IN THE BOUNDARY LAYER AND DEEPEN. EFFECTIVE BULK SHEAR MAGNITUDES AROUND 50 KT WILL PROMOTE SUPERCELLULAR STRUCTURES. GIVEN VERY HIGH EFFECTIVE STORM-RELATIVE HELICITY VALUES BETWEEN 500 TO 700 M2/S2...LOW-LEVEL ROTATION WILL BE A THREAT WITH ANY SUSTAINED SUPERCELLS /AS EVIDENT WITH THE EVOLVING SUPERCELL OVER CNTRL LAKE PONTCHARTRAIN AND MARION COUNTY MISSISSIPPI/ WITH AN ATTENDANT THREAT FOR TORNADOES. TORNADO WATCH 45 HAS BEEN EXPANDED SWD ACROSS SERN LA IN COORDINATION WITH WFO SLIDELL. ..COHEN.. 03/09/2011 Link to comment Share on other sites More sharing options...

VALID 091228Z - 091400Z THE SEVERE WEATHER THREAT FOR TORNADO WATCH 45 CONTINUES. THE TORNADO AND WIND DAMAGE THREAT ACROSS WW 45 WILL CONTINUE TO GRADUALLY MOVE EWD INTO FAR SE LA...FAR SRN MS...SRN AL AND THE WRN FL PANHANDLE. A NEW WW WILL BE NEEDED TO REPLACE WW 45 BEFORE THE 14Z EXPIRATION. A CLUSTER OF TORNADIC SUPERCELLS IS ONGOING ACROSS SE LA AND SRN MS LOCATED ON THE SWRN END OF A LINEAR MCS EXTENDING NEWD INTO CNTRL AL. THE STORMS ARE BEING SUPPORTED BY STRONG DEEP LAYER SHEAR AND ENHANCED LOW-LEVEL SHEAR PROFILES ASSOCIATED WITH A 55 TO 70 KT LOW-LEVEL JET. WSR-88D VWPS IN SRN MS CURRENTLY SHOW 0-3 KM HELICITIES IN THE 400 TO 550 M2/S2 RANGE WHICH COMBINED WITH LOW-LCL HEIGHTS WILL CONTINUE TO SUPPORT TORNADO DEVELOPMENT. A STRONG TORNADO COULD OCCUR WITH THE MORE DOMINANT SUPERCELL STORMS. WIND DAMAGE WILL ALSO BE POSSIBLE WITH SUPERCELLS AND WITH THE FASTER-MOVING BOWING LINE-SEGMENTS ESPECIALLY AS THE MORE DISCRETE STORMS CONGEAL INTO THE LINEAR MCS OVER THE NEXT FEW HOURS. THE STRONGER INSTABILITY IS CURRENTLY LOCATED ACROSS SRN MS AND FAR SRN AL SUGGESTING THE GREATEST SEVERE THREAT WILL REMAIN ACROSS THE SERN PART OF THE WATCH. ..BROYLES.. 03/09/2011 Link to comment Share on other sites More sharing options...
