MD 1522 CONCERNING SEVERE THUNDERSTORM WATCH 553... FOR PARTS OF WRN KY AND MIDDLE TN
MESOSCALE DISCUSSION 1522 NWS STORM PREDICTION CENTER NORMAN OK 0617 PM CDT SAT JUL 31 2010 AREAS AFFECTED...PARTS OF WRN KY AND MIDDLE TN CONCERNING...SEVERE THUNDERSTORM WATCH 553... VALID 312317Z - 010015Z THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 553 CONTINUES. REGIONAL RADAR IMAGERY AT 23Z INDICATES THAT STRONGEST STORM ACTIVITY IS OCCURRING ALONG THE ERN EDGE OF HOT SURFACE AIR MASS OVER MIDDLE TN...AS WELL AS PORTIONS OF WRN KY AHEAD OF S/W TROUGH LOCATED INVOF THE LWR OH VALLEY. THE HOT/VERY MOIST BOUNDARY LAYER AIR MASS CONTINUES TO MAINTAIN STRONG INSTABILITY ACROSS WW 553...FAVORABLE FOR A CONTINUED THREAT OF STRONG/SVR MULTICELLS AND EVEN BRIEF SUPERCELLS GIVEN EFFECTIVE BULK SHEAR VALUES RANGING FROM 30-40 KT. IN ADDITION...LARGE SCALE ASCENT ASSOCIATED WITH THE UPPER IMPULSE OBSERVED IN WV IMAGERY MAY AID IN CONTINUED STORM MAINTENANCE AND INTENSITY THROUGH THE EVENING HOURS. THUS...THREAT FOR DAMAGING WIND GUSTS AND LARGE HAIL IS EXPECTED TO CONTINUE THROUGH 02Z. ..GARNER.. 07/31/2010 ...PLEASE SEE WWW.SPC.NOAA.GOV FOR GRAPHIC PRODUCT...

MD 1519 CONCERNING SEVERE THUNDERSTORM WATCH 552... FOR MUCH OF GA AND SC
MESOSCALE DISCUSSION 1519 NWS STORM PREDICTION CENTER NORMAN OK 0600 PM CDT SAT JUL 31 2010 AREAS AFFECTED...MUCH OF GA AND SC CONCERNING...SEVERE THUNDERSTORM WATCH 552... VALID 312300Z - 010000Z THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 552 CONTINUES. MULTICELL STORM CLUSTERS CONTINUE TO MOVE SEWD ACROSS WW 552...SOME WITH A HISTORY OF PRODUCING DAMAGING WIND GUSTS. AREA SURFACE OBSERVATIONS INDICATE THAT THE AIR MASS IS SLOWLY BEGINNING TO COOL AND STABILIZE...DUE TO CONVECTIVE OUTFLOW FROM WIDESPREAD THUNDERSTORM COVERAGE...AS WELL AS DIURNAL COOLING TREND WITH THE APPROACH OF SUNSET. HOWEVER...POCKETS OF HIGHER INSTABILITY STILL EXIST...WITH LARGEST MLCAPE VALUES /UPWARDS OF 2500 J PER KG BASED ON OBJECTIVE ANALYSIS GUIDANCE/ OVER E-CENTRAL GA. THIS INSTABILITY COUPLED WITH SRN FRINGE OF STRONGER EFFECTIVE BULK SHEAR /30-40 KTS/ MAY AID IN A CONTINUED RISK FOR ISOLATED DAMAGING WIND GUSTS WITH THE STRONGER UPDRAFT CORES. IN ADDITION...STRONGLY BACKED LOW-LEVEL FLOW AND ENHANCED LOW-LEVEL VERTICAL WIND SHEAR IS OBSERVED OVER SC...WHICH MAY LEAD TO BRIEF UPDRAFT ROTATION AND OCCASIONAL SUPERCELL-LIKE STORM STRUCTURES. OTHERWISE...CONTINUED BOUNDARY LAYER STABILIZATION DURING THE REMAINDER OF WW 552 SHOULD RESULT IN A GRADUAL WEAKENING OF CONVECTION ACROSS THE AREA...AND WILL LIKELY PRECLUDE THE NEED FOR ADDITIONAL WW/S. ..GARNER.. 07/31/2010 ...PLEASE SEE WWW.SPC.NOAA.GOV FOR GRAPHIC PRODUCT...
