   Areas affected...Far Northeast SD...Central MN

   Concerning...Severe potential...Watch unlikely 

   Valid 021827Z - 022000Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Thunderstorms capable of isolated hail will continue
   across central MN for the next few hours.

   DISCUSSION...Storm cluster that was decaying/weakening as it moved
   into central MN early this morning has recently shown a
   strengthening trend as new storms develop along its southwestern
   flank. This re-strengthening may be a result of increasingly buoyant
   air being advected northward over the cold front into the vicinity
   of the storm cluster. Given the overall progression of this cluster,
   the potential for storms in far northeast SD remains low, with the
   higher probability for thunderstorms across west-central into
   southwest MN. Several storms within the cluster have shown mid-level
   rotation, although persistence of this rotation has been somewhat
   transient. 

   Destabilizing air mass downstream suggests that thunderstorms will
   likely persist across west-central/central MN for at least the next
   hour or two. Vertical shear will remain modest (i.e. 0-6 km bulk
   shear around 30 kt) but still strong enough when coupled with the
   steep mid-level lapse rates (9 deg C per km on the 18Z MPX sounding)
   to support occasional updraft rotation with an attendant threat for
   isolated hail.
