   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 248
   CONTINUES.
   
   THE WIND DAMAGE AND HAIL THREAT SHOULD EXPAND EWD AS A PERSISTENT
   LINEAR MCS MOVES INTO SE MO AND NCNTRL AR. ATTM...WW ISSUANCE
   APPEARS LIKELY EAST OF WW 248 ACROSS SW IL...SE MO AND ERN AR.
   
   LATEST SFC ANALYSIS SHOWS A 994 MB LOW OVER FAR NW MO WITH A COLD
   FRONT ADVANCING SEWD ACROSS ERN KS AND ERN OK. A DYNAMIC UPPER-LEVEL
   LOW OVER THE CNTRL PLAINS IS CREATING STRONG LARGE-SCALE ASCENT
   WHICH IS SUPPORTING THE LINEAR MCS. IN ADDITION...A 50 TO 60 KT
   LOW-LEVEL JET IS LOCATED JUST EAST OF THE LINEAR MCS AND THIS ALONG
   WITH SUFFICIENT INSTABILITY WILL LIKELY KEEP THE LINE ORGANIZED FOR
   SEVERAL MORE HOURS. REGIONAL WSR-88D VWPS AHEAD OF THE LINE SHOW
   ABOUT 55 KT OF FLOW AT 1 KM SUGGESTING THE WIND DAMAGE THREAT MAY
   CONTINUE WITH BOWING SEGMENTS IN THE LINE HAVING THE GREATEST SEVERE
   POTENTIAL.
