VALID 102320Z - 110015Z THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 370 CONTINUES. SUMMARY...THUNDERSTORMS WILL GRADUALLY INCREASE ALONG THE COLD FRONT AS IT PROGRESSES ACROSS WRN IA/SERN NEB...POSSIBLY INTO NERN KS OVER THE NEXT FEW HOURS. DISCUSSION...MULTIPLE THUNDERSTORM CLUSTERS HAVE EVOLVED ACROSS WRN IA ALONG/AHEAD OF COLD FRONT. ONE OR TWO OF THE STRONGEST UPDRAFTS APPEAR TO BE PRODUCING GOLF BALL SIZE HAIL AND THE OVERALL TRENDS SUGGEST ADDITIONAL DEVELOPMENT WILL OCCUR ACROSS THIS REGION AS THE COLD FRONT UNDERCUTS THIS ACTIVITY ENHANCING LIFT. LATEST VIS IMAGERY DEPICTS A DEEPENING BAND OF CU ALONG THE COLD FRONT AS IT SAGS SEWD ACROSS SERN NEB/KS AT ROUGHLY 15KT. MID DAY SOUNDING FROM LMN SUGGESTS A CAP CONTINUES SOUTH OF I-70 SO ANY TSTMS THAT DEVELOP ALONG THE TRAILING FRONT IN THE SHORT TERM WILL LIKELY BE NEAR THE NEB BORDER. ..DARROW.. 06/10/2012 ...PLEASE SEE WWW.SPC.NOAA.GOV FOR GRAPHIC PRODUCT...
