andyhb Posted May 30, 2013 Share Posted May 30, 2013 MESOSCALE DISCUSSION 0887 NWS STORM PREDICTION CENTER NORMAN OK 0552 PM CDT THU MAY 30 2013 AREAS AFFECTED...NCNTRL TX THROUGH CNTRL AND ERN OK CONCERNING...TORNADO WATCH 252...254... VALID 302252Z - 310045Z THE SEVERE WEATHER THREAT FOR TORNADO WATCH 252...254...CONTINUES. SUMMARY...THREAT FOR LARGE HAIL AND ISOLATED TORNADOES WILL PERSIST THROUGH MID EVENING FROM NCNTRL TX THROUGH CNTRL AND ERN OK. TORNADO THREAT COULD INCREASE BETWEEN 23-02Z BEFORE DECREASING AGAIN LATER IN THE EVENING. DISCUSSION...STORMS THAT DEVELOPED ALONG ENE-WSW ORIENTED OUTFLOW BOUNDARY AS WELL AS ON DRYLINE CIRCULATION REMAIN MOSTLY DISCRETE FROM NCTRL TX THROUGH CNTRL AND NERN OK. STORMS FROM NCNTRL TX THROUGH CNTRL OK HAVE MOVE AWAY FROM THE DRYLINE INTO THE UNSTABLE WARM SECTOR WHERE MLCAPE FROM 2500-3500 J/KG EXISTS. THIS ACTIVITY WILL LIKELY CONTINUE TO POSE A THREAT FOR LARGE HAIL AND DAMAGING WIND NEXT FEW HOURS. THE LLJ IS EXPECTED TO STRENGTHEN THIS EVENING...RESULTING IN LARGER 0-2 KM HODOGRAPHS IN WARM SECTOR THAN EARLIER TODAY. THIS MAY ENHANCE THE POTENTIAL FOR STORMS TO BETTER ORGANIZE LOW LEVEL MESOCYCLONES WITH AN ATTENDANT INCREASE IN TORNADO THREAT IN A RELATIVELY SMALL WINDOW BEFORE THE NEAR SFC LAYER BEGINS TO STABILIZE WITH ONSET OF NOCTURNAL COOLING. ..DIAL.. 05/30/2013 Link to comment Share on other sites More sharing options...
