   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 862
   CONTINUES.
   
   TORNADO WATCH 862 CONTINUES UNTIL 05Z. WHILE A TORNADO MAY STILL BE
   POSSIBLE...DAMAGING WINDS/SOME SEVERE HAIL...ALONG WITH HEAVY
   RAINFALL...WILL BE THE PRIMARY CONCERNS.
   
   FOCUSED ALONG A CONVECTIVELY REINFORCED BOUNDARY IMMEDIATELY EAST OF
   A SURFACE FRONT...SCATTERED TO NUMEROUS TSTMS CONTINUE TO OCCUR
   WITHIN A NORTHEAST-SOUTHWEST ORIENTED CORRIDOR ACROSS
   SOUTH-CENTRAL/EAST-CENTRAL NEB. AS SURFACE TEMPERATURES CONTINUE TO
   COOL THROUGH THE LOWER 70S/UPPER 60S F...A CORRESPONDING INCREASE IN
   NEAR-SURFACE CINH SHOULD GRADUALLY BEGIN TO TEMPER THE SEVERE
   WIND/POTENTIAL TORNADO THREAT. NONETHELESS...A HIGHLY SHEARED
   ENVIRONMENT ACCENTUATED BY 300+ M2/S2 0-2 KM SRH /AS PER THE
   HASTINGS WSR-88D VWP/ WILL CONTINUE TO YIELD A FEW EMBEDDED
   SUPERCELLS/NORTHEAST-RACING SMALL BOWS CAPABLE OF DAMAGING
   WINDS/PERHAPS A BRIEF TORNADO ESPECIALLY ACROSS SOUTH-CENTRAL NEB.
   ADDITIONALLY...THE GRADUALLY WESTWARD-RETREATING SURFACE
   BOUNDARY/ASSOCIATED MOIST AXIS WILL LIKELY RESULT IN A WESTWARD
   EXPANSION OF TSTMS INTO THE OVERNIGHT.
