   Minnesota

   Concerning...Severe Thunderstorm Watch 342...

   Valid 080637Z - 080830Z

   The severe weather threat for Severe Thunderstorm Watch 342
   continues.

   SUMMARY...A severe threat will be likely across eastern North Dakota
   over the next hour. The threat is also expected to affect northwest
   and north-central Minnesota. Wind damage, isolated large hail and a
   brief tornado will be possible. Weather watch issuance or a local
   extension in area may be needed as the convective line moves toward
   the edge of WW 342 in a couple hours.

   DISCUSSION...The latest radar imagery shows a well-developed linear
   MCS across eastern North Dakota. The MCS was comprised of a
   fast-moving bowing line segment with a warm advection wing extending
   southeastward into far southeast North Dakota. The line of severe
   storms is being supported by a deep rear inflow jet which appears
   maximized from 5,000 to 17,000 ft looking from the Grand Forks
   radar. Convection associated with this MCS is moving to the east
   near 50 kt. This will be favorable for wind damage along the leading
   edge of the bow echo. The station 46D at Carrington, North Dakota
   recorded a 52 kt wind gust as the bowing segment passed. Isolated
   wind damage and large hail may also occur with the stronger cores
   along the warm advection wing. A QLCS tornado and isolated large
   hail can not be ruled out with rotating cells embedded in the line.
   The line of severe storms should approach the edge of WW 342 around
   08Z necessitating an watch extension or new watch.
