   ...W TX EWD ACROSS THE SRN HALF OF AL...
   LIMITED SEVERE THREAT WILL PERSIST EWD ACROSS THE LOWER MS VALLEY
   INTO THE SOUTHEAST INVOF COLD FRONT.  MOIST / UNSTABLE AIRMASS
   ACROSS THIS REGION COMBINED WITH SUFFICIENT DEEP-LAYER SHEAR FOR
   SOME STORM ORGANIZATION SUGGESTS THAT HAIL / LOCALLY DAMAGING WINDS
   WILL BE POSSIBLE WITH A FEW OF THE STRONGER STORMS -- PARTICULARLY
   THROUGH THIS EVENING.
   
   GREATER SEVERE THREAT EXISTS FURTHER W INTO TX...WHERE MODERATE
   INSTABILITY /1500 TO 2000 J/KG MEAN-LAYER CAPE/ IS INDICATED.  COLD
   FRONT IS NOW MOVING ACROSS N TX / THE RED RIVER VALLEY REGION...AND
   WILL CONTINUE MOVING SWD WITH TIME.  
   
   WITH SEVERAL SUBTLE UPPER IMPULSES TO MOVE ACROSS THE SRN PLAINS
   WITHIN MODERATE SWLY FLOW AHEAD OF WRN U.S. UPPER LOW...EXPECT
   LOW-LEVEL JET TO INCREASE OVERNIGHT.  THIS SHOULD ALLOW ELEVATED
   STORMS -- AND THREAT FOR MARGINAL HAIL -- TO INCREASE WITHIN ZONE OF
   ISENTROPIC LIFT N OF SWD-MOVING SURFACE FRONT. FURTHER S / WITHIN
   THE WARM SECTOR...LOW-LEVEL SELY FLOW BENEATH MODERATE UPPER LEVEL
   WINDS ARE YIELDING SUFFICIENT DEEP-LAYER SHEAR FOR ORGANIZED /
   ROTATING UPDRAFTS.  LARGE HAIL AND LOCALLY DAMAGING WIND THREAT WILL
   PERSIST...WITH GREATEST THREAT SHIFTING SLOWLY EWD ACROSS TX THROUGH
   THE END OF THE PERIOD.
   
   ...SRN CA / WRN AND CENTRAL AZ...
   LIMITED SEVERE THREAT WILL PERSIST THROUGH THE PERIOD ACROSS THIS
   REGION AS UPPER LOW CONTINUES MOVING SEWD ALONG THE SRN CA COAST. 
   INSTABILITY IS LIMITED ACROSS MOST OF THE REGION...THOUGH 500 TO
   1000 J/KG MEAN-LAYER CAPE INDICATED ACROSS PARTS OF AZ S OF THE
   MOGOLLON RIM.  WITH MODERATE / DIFFLUENT UPPER FLOW ACROSS THIS
   REGION...THREAT FOR HAIL AND LOCALLY DAMAGING WINDS WILL CONTINUE
   WITH ORGANIZED / POSSIBLY ROTATING STORMS.
   
   FURTHER W INTO SRN CA...INSTABILITY IS MUCH MORE LIMITED AND SHEAR
   SHOULD REMAIN MUCH WEAKER GIVEN PROXIMITY TO UPPER LOW CENTER. 
   NONETHELESS...A STRONGER LOW-TOPPED STORM OR TWO MAY PRODUCE A
   LOCALLY STRONG WIND GUST / ISOLATED TORNADO THROUGH THE END OF THE
   PERIOD.
