   Areas affected...portions of southern MN

   Concerning...Severe Thunderstorm Watch 462...

   Valid 280904Z - 281030Z

   The severe weather threat for Severe Thunderstorm Watch 462
   continues.

   SUMMARY...Strong to severe wind gusts will continue this morning
   across portions of southern MN.

   DISCUSSION...A mature bow echo continues to track generally eastward
   around 40-50 kt across southern MN early this morning. The southern
   half of the bow appears to be intensifying per increases in 5 and 7
   km CAPPI and an increase in forward motion over the past 30-60
   minutes. Meanwhile, VWP data from KMPX and KFSD show a healthy rear
   inflow jet of around 40-50 kt. This is further evident in decreased
   reflectivity just behind the bow. Most surface observation sites
   have measured gusts around 35-46 kt over the past 1-2 hours. This
   suggest stronger gusts may be somewhat impacted by low level
   inhibition. However, the bow had been moving slightly north of east
   into lower dewpoints and slightly cooler surface temperatures in the
   vicinity of a surface boundary draped across west-central into
   southeast MN.

   Expect that severe gusts will continue to be possible into the
   morning hours, along and south of the surface boundary. Upper 60s to
   low 70s dewpoints reside across this area, and should support
   continued increase in southern portion of the bow.
