   ...THERE IS A SLGT RISK OF SVR TSTMS FROM EXTREME E CNTRL NM THROUGH
   PARTS OF NW TX AND THE TX PANHANDLE...
   
   THIS EVENING A COLD FRONT EXTENDS FROM A SURFACE LOW IN WRN MN SWWD
   THROUGH CNTRL KS...THE TX PANHANDLE AND INTO ERN NM. A PRE-FRONTAL
   BOUNDARY EXTENDS FROM E CNTRL NM NEWD INTO THE TX PANHANDLE WHERE IT
   INTERSECTS THE FRONT. THE WARM SECTOR REMAINS MODERATELY UNSTABLE
   FROM ERN NM INTO NW TX AND THE SRN TX PANHANDLE WITH MLCAPE FROM
   1000 TO 1500 J/KG. STRONG MID LEVEL JET ROUNDING BASE OF HIGH PLAINS
   UPPER TROUGH IS CONTRIBUTING TO 0-6 KM SHEAR OF 40 TO 50 KT IN THIS
   AREA. STORMS SHOULD CONTINUE DEVELOPING ALONG FRONT AND PRE-FRONTAL
   TROUGH THE REMAINDER OF THE EVENING WITH STRONGEST STORMS...
   INCLUDING A FEW SUPERCELLS...EXPECTED TO PERSIST THROUGH 04Z FROM
   THE SRN TX PANHANDLE INTO NW TX. STORMS IN THE TX PANHANDLE ARE
   BEING UNDERCUT BY THE OUTFLOW REINFORCED COLD FRONT...BUT MAY STILL
   BE CAPABLE OF PRODUCING HAIL. STORMS DEVELOPING FARTHER SOUTH FROM
   ERN NM INTO NW TX WILL LIKELY REMAIN SURFACE BASED NEXT COUPLE
   HOURS.
   
   
   WITH TIME...STRONGEST DEEP LAYER FORCING FOR ASCENT WILL SHIFT NEWD
   AWAY FROM THE STRONGER INSTABILITY AS THE UPPER TROUGH AND ITS
   ASSOCIATED LOW LEVEL JET LIFT NE INTO THE CNTRL PLAINS OVERNIGHT.
   THIS IN CONJUNCTION WITH DECREASING INSTABILITY ASSOCIATED WITH THE
   COOLING BOUNDARY LAYER SUGGEST THE SEVERE THREAT WILL LIKELY NOT
   PERSIST BEYOND ABOUT 04Z.
