   VALID 040118Z - 040215Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 543 CONTINUES.
   
   EARLY EVENING SURFACE ANALYSIS INDICATED A BOUNDARY EXTENDING ESEWD
   FROM THE STORM IN OTTAWA COUNTY KS TO WEST CENTRAL MO...WHILE
   ANOTHER BOUNDARY/OUTFLOW BOUNDARY EXTENDS EWD FROM FAR SRN NEB INTO
   FAR NRN MO.  A VERY MOIST AND UNSTABLE AIR MASS ALONG AND S OF THE
   FORMER BOUNDARY IN NERN KS COMBINED WITH EFFECTIVE BULK SHEAR AROUND
   50 KT WILL MAINTAIN POTENTIAL FOR STRONG TO SEVERE STORMS THIS
   EVENING.  ALTHOUGH OBJECTIVE ANALYSES SUGGEST SURFACE BASED
   INHIBITION IS INCREASING ACROSS THIS REGION...BUT PROXIMITY OF
   OTTAWA STORM TO THE SURFACE BOUNDARY AND 30 KT SLY LLJ INTO THIS
   REGION SUGGESTS STORM MAY STILL BE SURFACE BASED WITH AN ATTENDANT
   THREAT FOR ISOLATED TORNADOES.
