Areas affected...east central Minnesota into northwestern Wisconsin

Concerning...Tornado Watch 526...

Valid 290359Z - 290530Z

The severe weather threat for Tornado Watch 526 continues.

SUMMARY...A substantive further increase in organization appears
unlikely as a cluster of storms spreads across and north of the Twin
Cities into northwestern Wisconsin through Midnight-2 AM CDT.
Occasional gusty winds remain possible, but activity is expected to
generally remain below severe limits and a new severe weather watch
probably will not be needed.

DISCUSSION...Within large-scale ascent associated with low-level
warm advection (roughly in the 925-850 mb layer), convection has
tended to consolidate into an evolving, but still rather
disorganized thunderstorm cluster.  It appears that this largely has
remained focused just ahead of the leading edge of the stronger
mid-level cooling, with convective intensities suppressed by
substantive mid-level inhibition.  As convection advances eastward
into northwestern Wisconsin during the next couple of hours, it will
begin to overspread a somewhat cooler, drier and more stable
boundary-layer.  While convection may be maintained by elevated
inflow of moist unstable air from the southwest, an appreciable
increase in potential for severe wind gusts appears unlikely.
