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.
