   Concerning...Severe Thunderstorm Watch 579...

   Valid 311838Z - 312015Z

   The severe weather threat for Severe Thunderstorm Watch 579
   continues.

   SUMMARY...A well developed bow echo will continue to produce
   damaging gusts in the 60-80 mph range across west-central MN. This
   activity will likely remain severe into portions of
   northeast/east-central MN and perhaps far northwest WI, and a new
   severe thunderstorm watch will likely be needed downstream from WW
   579.

   DISCUSSION...A well developed bow echo is moving across west-central
   MN within a strongly unstable airmass characterized by dewpoints in
   the low 70s F and steep midlevel lapse rates. While vertical shear
   weakens with northward extent, latest mesoanalysis and region VWP
   data suggest effective shear magnitudes have increased across
   northeast/east-central MN. Furthermore, VWP data from KABR has
   measured rear-inflow around 55-70 kt between 3-6 km. Given favorable
   low-level moisture, strong instability and at least modestly
   favorable vertical shear, expect this bow echo will continue
   east/northeast and a downstream watch will likely be needed.
