SPC AC 080048 DAY 1 CONVECTIVE OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 0748 PM CDT SAT APR 07 2012 VALID 080100Z - 081200Z ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE SRN PLAINS... ...SRN PLAINS... A LINE OF STRONG TO SEVERE THUNDERSTORMS IS ONGOING IN WCNTRL TX ALONG A WELL-DEFINED COLD FRONT. SOUTH OF THE FRONT...SFC DEWPOINTS ARE IN THE LOWER 60S F AND MLCAPE VALUES ARE ESTIMATED IN THE 1500 TO 2500 J/KG RANGE. THIS ALONG WITH ENHANCED LOW-LEVEL CONVERGENCE ALONG THE BOUNDARY SHOULD HELP MAINTAIN THE STORMS FOR SEVERAL MORE HOURS WITH A SLOW SWD TRANSITION ACROSS THE SLIGHT RISK AREA. STEEP LAPSE RATES ACROSS WCNTRL TX WILL CONTINUE TO SUPPORT AN ISOLATED THREAT FOR LARGE HAIL. A TORNADO WILL ALSO BE POSSIBLE WITH THE MOST DOMINANT CELL EMBEDDED IN THE LINE OVER THE NEXT HOUR OR SO. HOWEVER...THE POTENTIAL FOR SUPERCELLS SHOULD LESSEN WITH TIME THIS EVENING AS THE LINE ENCOUNTERS WEAKER SHEAR PROFILES TO THE SOUTH. A WIND DAMAGE THREAT SHOULD ALSO EXIST WITH THE LINE WITH THE MOST WIDESPREAD POTENTIAL SOUTHWEST OF SAN ANGELO WHERE MESOANALYSIS SUGGESTS INSTABILITY IS THE STRONGEST. A GRADUAL DECREASE IN THE SEVERE THREAT SHOULD TAKE PLACE THIS EVENING WITH THE THREAT PROBABLY BECOMING MARGINAL AFTER 03Z. ..BROYLES.. 04/08/2012 CLICK TO GET WUUS01 PTSDY1 PRODUCT NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 0600Z
