   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 337
   CONTINUES.
   
   THE SEVERE THREAT ACROSS THE ERN PART OF WW 337 MAY EXPAND EWD
   ACROSS SE MO EARLY THIS AFTERNOON. LARGE HAIL AND ISOLATED WIND
   DAMAGE WILL BE POSSIBLE WITH THE MORE INTENSE LINE-SEGMENTS. WW
   ISSUANCE MAY BECOME NECESSARY ACROSS SE MO AND NRN AR OVER THE NEXT
   HOUR.
   
   AN MCS LOCATED FROM NEAR LEBANON MO EXTENDING SWWD TO JUST SOUTH OF
   JOPLIN MO WILL CONTINUE TO MOVE ESEWD INTO SE MO AND FAR NRN AR. THE
   STORMS ARE LOCATED ALONG THE NRN EDGE OF MODERATE INSTABILITY WITH
   MESOANALYSIS ESTIMATED MLCAPE VALUES RANGING FROM 2000 TO 3000 J/KG.
   IN ADDITION...A 30 TO 40 KT JET AT 700 MB IS ANALYZED JUST BEHIND
   THE MCS IN FAR NE OK. THIS FEATURE ALONG WITH A POCKET OF STRONG
   INSTABILITY IS LIKELY PROVIDING SUPPORT FOR AN ISOLATED WIND DAMAGE
   THREAT WITH THE MCS. THIS THREAT MAY DEVELOP EWD ACROSS SE MO EARLY
   THIS AFTERNOON. THE STRONGER CORES WITHIN THE MCS MAY ALSO CONTAIN A
   THREAT FOR LARGE HAIL.
