   VALID 260004Z - 260130Z

   PROBABILITY OF WATCH ISSUANCE...20 PERCENT

   SUMMARY...ISOLATED SEVERE RISK IN THE FORM OF LARGE HAIL AND WIND
   MAY PERSIST THROUGH ABOUT SUNSET...BUT SHOULD WEAKEN THEREAFTER AND
   MITIGATE THE NEED FOR A WW ISSUANCE.

   DISCUSSION...A FEW PROBABLE SEVERE STORMS HAVE FORMED ALONG THE
   QUASI-STATIONARY FRONT ARCING FROM CNTRL KS SWWD TO THE RATON MESA.
   WITHIN A HOT/DEEPLY-MIXED THERMODYNAMIC ENVIRONMENT...STEEP
   TROPOSPHERIC LAPSE RATES AS SAMPLED BY 00Z DDC RAOB WILL FAVORABLY
   SUPPORT A CONTINUED ISOLATED SEVERE HAIL/WIND RISK. BUT AMIDST
   MODEST DEEP SHEAR...UPDRAFTS HAVE THUS FAR APPEARED SOMEWHAT
   PULSE-LIKE AND REMAIN TIED TO THE FRONT/STORM-SCALE OUTFLOW. THE
   ONSET OF NOCTURNAL SURFACE COOLING/INCREASING MLCIN IN THE ABSENCE
   OF A ROBUST LLJ SHOULD RESULT IN CONVECTION DECAYING WITHIN AN HOUR
   OR SO OF SUNSET.
