Areas affected...southeast Minnesota...southwest
Wisconsin...northeast Iowa

Concerning...Severe potential...Watch unlikely 

Valid 280821Z - 281045Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated cells capable of hail or wind may persist across
this area for much of the night.

DISCUSSION...A northwest-southeast oriented zone of storms currently
exists from southeast MN into central WI, within the 850 mb theta-e
axis. Instability is strong due to steep lapse rates aloft and
boundary layer dewpoints approaching 70 F. 

Storms are currently regenerating over the same areas as
southwesterly 850 mb winds maintain warm/moist advection. Sporadic
severe hail or near-severe wind gusts are possible with the leading
cell over Fillmore County, and with new development tonight possibly
into IA as outflow shifts ascent southwestward with time. Unless
storms organize into a more substantial MCS with wind threat, a
watch appears unlikely tonight.
