   Areas affected...southeast South dakota...southwest Minnesota...and
   western Iowa

   Concerning...Severe potential...Watch unlikely 

   Valid 081917Z - 082045Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A few stronger storms are possible this afternoon from
   southeast South Dakota into southwest Minnesota and western Iowa.

   DISCUSSION...An arcing band of showers/thunderstorms has started to
   appear on radar from southeast South Dakota into southwest Minnesota
   and into western Iowa. Moisture is lacking in this area, but cold
   air aloft (beneath the mid-level low) is supporting substantial
   instability and the potential for some stronger thunderstorms this
   afternoon. Cloud bases are high, but given the steep low-level lapse
   rates beneath an occluding low, some potential for
   landspout/non-supercell tornadoes exists.
