CONCERNING...SEVERE THUNDERSTORM WATCH 213...214...

VALID 260118Z - 260245Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
213...214...CONTINUES.

SUMMARY...THE THREAT FOR SOME MARGINALLY SEVERE HAIL AND/OR STRONG
WIND GUSTS CONTINUES THIS EVENING...BUT SHOULD GRADUALLY DIMINISH
OVER THE NEXT FEW HOURS.

DISCUSSION...THE CURRENT WSR-88D MOSAIC DEPICTS A SOMEWHAT NEBULOUS
CONVECTIVE EVOLUTION ACROSS MUCH OF WW 213 AND 214...WITH A BROKEN
BAND OF STRONG STORMS OVER NWRN MO/NERN KS AND SOME SLIGHTLY
ELEVATED /BUT STILL STRONG/ CELLS OVER FAR WRN PORTIONS OF WW 214.
ONGOING ORGANIZED UPDRAFTS AND NEW CONVECTIVE DEVELOPMENT RESULTING
FROM OUTFLOW MERGERS/ENHANCED SFC CONVERGENCE WILL STILL HAVE SOME
MARGINAL POTENTIAL TO PRODUCE LARGE HAIL/STRONG WIND GUSTS OVER THE
NEXT COUPLE OF HOURS...FACILITATED BY APPROX 1000-1500 J/KG OF
REMAINING MLCAPE AND DEEP-LAYER SHEAR AROUND 30 KT /SAMPLED BY KDMX
VWP/. HOWEVER...CONVECTIVE OVERTURNING AND NOCTURNAL COOLING SHOULD
ENABLE A GRADUAL DECREASE IN THE THREAT THIS EVENING...WITH THE
GREATEST RELATIVE POTENTIAL PERSISTING OVER SERN PORTIONS OF WW 214.
