   ...W TX/SRN OK...
   OBJECTIVE ANALYSIS SHOWS AN AXIS OF 55-62 F SFC DEWPOINTS ACROSS WRN
   TX AND SERN NM WHERE MLCAPE VALUES HAVE RISEN TO AROUND 500 TO 1000
   J/KG THIS AFTERNOON. SCATTERED STORMS HAVE DEVELOPED IN THE MTNS AND
   SHOULD MOVE SLOWLY EWD INTO THE LOWER ELEVATIONS LATE THIS
   AFTERNOON. LARGE-SCALE ASCENT ASSOCIATED WITH A SHORTWAVE EVIDENT ON
   WV IMAGERY ACROSS WRN KS AND ERN CO SHOULD BE SUFFICIENT FOR
   ADDITIONAL STORM DEVELOPMENT ACROSS W TX THROUGH THIS EVENING.
   OBJECTIVE ANALYSIS SHOWS DEEP LAYER SHEAR OF 30 TO 40 KT IN PLACE
   MAINLY NORTH OF AN EL PASO TO MIDLAND LINE. THIS COMBINED WITH THE
   INSTABILITY AND MODERATELY STEEP LAPSE RATES...MAY BE ENOUGH FOR
   MARGINALLY SEVERE STORMS. AS THE UPPER-LEVEL SHORTWAVE MOVES EWD
   TONIGHT...THE STORMS WILL MOVE CLOSER TO THE DEVELOPING LOW-LEVEL
   JET IN NCNTRL TX AND SRN OK. THIS WILL SUPPORT ELEVATED STORMS AND A
   POTENTIAL FOR ISOLATED HAIL MAY CONTINUE OVERNIGHT. DUE TO THE WEAK
   INSTABILITY IN PLACE...THE SEVERE THREAT WILL REMAIN TOO MINIMAL FOR
   A SLIGHT RISK ACROSS THE AREA.
