   Areas affected...Southeastern Iowa and far northeastern Missouri

   Concerning...Tornado Watch 29...

   Valid 060151Z - 060345Z

   The severe weather threat for Tornado Watch 29 continues.

   SUMMARY...Storm mode has trended more linear in WW 29. Low-level
   wind fields will still support damaging wind gusts and brief

   DISCUSSION...Modest destabilization continues ahead of a broken line
   of quasi-linear storms in eastern Iowa and far northeastern
   Missouri. Though storm mode has trended less discrete, regional
   radar velocity data has shown periodic embedded circulations
   developing within the line segments. A couple of measured severe
   gusts were reported within the last hour in eastern Iowa. Given the
   strong low-level shear and veering seen on the KDVN VWP, there will
   be continued potential for this sort of activity. Damaging winds and
   brief tornadoes will be the primary threats. The observed DVN 00Z
   sounding showed an 8 C/km mid-level lapse rate which would also
   support marginally severe hail, despite the less favorable storm
