   FAST WEST-NORTHWEST FLOW PATTERN IS PRESENT OVER THE CENTRAL UNITED
   STATES TODAY...WITH SEVERAL WEAK SHORTWAVE TROUGHS TRACKING THROUGH
   THE REGION.  SOUTHERLY LOW LEVEL WINDS ARE TRANSPORTING GULF
   MOISTURE RAPIDLY NORTHWARD ACROSS TX/OK/KS...DESTABILIZING THE
   AIRMASS AND AIDING IN SCATTERED ELEVATED THUNDERSTORMS OVER
   SOUTHEAST KS/NORTHEAST OK.  FURTHER ELEVATED STORMS ARE EXPECTED AS
   FAR NORTH AS SD/IA TODAY...WHILE POTENTIAL EXISTS FOR DEVELOPMENT
   ALONG THE DRYLINE OVER WESTERN KS/OK/TX.
   
   ...ERN SD/ERN NEB/WRN IA/ERN KS/WRN MO/ERN OK...
   SOUTHERLY LOW LEVEL WINDS AND WARM ADVECTION HAVE AIDED IN
   SUSTAINING STRONG/SEVERE STORMS THIS MORNING OVER SOUTHEAST KS. 
   THIS ACTIVITY WILL LIKELY CONTINUE THROUGH THE EARLY AFTERNOON AS
   AIRMASS AHEAD OF THE STORMS SLOWLY DESTABILIZES.  OTHER DEVELOPMENT
   IS EXPECTED ALONG AN AXIS FROM CURRENT CONVECTION INTO EASTERN
   NEB/WESTERN IA AND PERHAPS AS FAR NORTH AS EASTERN SD.  THE MORNING
   CONVECTIVE CLUSTER OVER KS MAY HAVE LESSENED THE MOIST INFLOW
   FARTHER NORTH.  HOWEVER...STEEP MID LEVEL LAPSE RATES AND MODERATE
   ELEVATED INSTABILITY WILL POSE A RISK OF LARGE HAIL WITH THESE
   STORMS.  OUTFLOW BOUNDARY FROM MORNING STORMS MAY ALSO RESULT IN
   AFTERNOON SEVERE/SUPERCELL STORMS OVER CENTRAL/EASTERN KS.  THIS
   WOULD APPEAR TO BE THE AREA WITH THE GREATEST RISK OF ISOLATED
   TORNADOES THIS AFTERNOON.
   
   ...WESTERN KS/OK/TX...
   LATEST SURFACE ANALYSIS SHOWS SURFACE DEWPOINTS RISING WELL INTO
   THE MID/UPPER 60S OVER WEST TX AND INTO WESTERN OK.  STRONG DAYTIME
   HEATING WILL ALLOW DRYLINE TO MIX EASTWARD TO ROUGHLY THE TX/OK
   BORDER...SOUTHWARD TO NEAR P07.  MODELS DISAGREE ON DEGREE OF
   FORCING AND CONVECTIVE POTENTIAL ALONG THIS AXIS.  HOWEVER...VERY
   UNSTABLE CONDITIONS...STRONG DEEP LAYER SHEAR...AND ONLY A WEAK CAP
   SUGGEST THE THREAT OF ISOLATED DEVELOPMENT THIS AFTERNOON/EVENING. 
   THOSE STORMS THAT DEVELOP SHOULD BECOME QUICKLY SEVERE WITH A LARGE
   HAIL AND DAMAGING WIND THREAT.
