   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF
   THE UPPER MIDWEST...

   ...SUMMARY...
   Severe thunderstorms will be possible Friday across portions of the
   upper Midwest.

   ...Upper Midwest Region...
   An upper-level low will continue east across Manitoba/western
   Ontario Provinces Friday, with a surface cold front likely extending
   from near the MN Arrowhead southwest to near the NE/SD border by
   late afternoon.  Despite some veering of the low-level flow,
   dewpoints will likely range in the mid-upper 60s in advance of the
   front.  Mid-level lapse rates are not expected to be particularly
   steep, though sufficient for moderate buoyancy (MLCAPE 1500-2000
   J/kg) to develop by afternoon.  Thunderstorms should develop on an
   isolated to widely scattered basis Friday afternoon/evening near the
   front, with some severe risk in the presence of northwesterly shear
   averaging 30-40 kts. The severe risk should begin to wane later
   Friday evening with the onset of nocturnal cooling.
