   CONCERNING...SEVERE THUNDERSTORM WATCH 860...
   
   VALID 070542Z - 070715Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 860
   CONTINUES.
   
   THE SEVERE THREAT ACROSS NW KS AND FAR SRN NEB WILL LIKELY BECOME
   INCREASINGLY ISOLATED OVER THE NEXT FEW HOURS. HOWEVER...AN ISOLATED
   WIND DAMAGE THREAT SHOULD PERSIST WITH THE STRONGER BOWING
   LINE-SEGMENTS WITHIN THE LINE. FOR THIS REASON...A LOCAL EXTENSION
   MAY BECOME NECESSARY OVERNIGHT ACROSS PARTS OF NW KS AND FAR SRN
   NEB.
   
   A LINE OF STRONG THUNDERSTORMS IS ONGOING FROM JUST WEST OF HILL
   CITY KS SWWD TO NORTHWEST OF DODGE CITY KS ALONG AN AXIS OF ENHANCED
   MOISTURE AND LOW-LEVEL CONVERGENCE. ALTHOUGH INSTABILITY IS VERY
   WEAK ACROSS THE WATCH AREA...STRONG LARGE-SCALE ASCENT ASSOCIATED
   WITH A DISTURBANCE EVIDENT ON WATER VAPOR IMAGERY AND LIFT ON THE
   WRN EDGE OF A  70 TO 85 KT LOW-LEVEL JET WILL PROVIDE SUPPORT FOR
   THE LINE FOR SEVERAL MORE HOURS. STRONG WIND FIELDS ASSOCIATED WITH
   A LOW-LEVEL JET IN THE CNTRL PLAINS AND MID-LEVEL JET MOVING OUT OF
   THE CNTRL ROCKIES WILL LIKELY ENABLE THE LINE TO REMAIN SEVERE
   DURING PART OF THE OVERNIGHT PERIOD WITH ISOLATED DAMAGING WIND
   GUSTS POSSIBLE.
