Areas affected...Portions of east-central Minnesota into far
northwestern Wisconsin

Concerning...Tornado Watch 406...

Valid 130123Z - 130230Z

The severe weather threat for Tornado Watch 406 continues.

SUMMARY...The risk of large hail, locally damaging gusts, and a
tornado or two will continue across parts of east-central Minnesota
into far northwestern Wisconsin for the next couple hours.

DISCUSSION...Latest radar data from KDLH indicates an
east/west-oriented band of semi-discrete supercells across Aitkin
and Pine Counties in east-central MN -- generally focused along an
antecedent outflow boundary. Lower/middle 60s dewpoints immediately
south of the boundary should continue to provide moderately unstable
inflow for these storms, while around 200 m2/s2 0-500m SRH favors
persistent low/midlevel mesocyclones. Given the favorable
environment and semi-discrete updrafts, these storms will have the
best chance of producing a tornado or two and isolated large hail in
the near-term.

Farther south (just north of the Minneapolis metro area), locally
damaging gusts and isolated large hail could accompany a loosely
organized band of storms, and a brief tornado cannot be entirely
ruled out owing to the aforementioned favorable low-level SRH.
However, these storms are impinging on increased MLCINH owing to
cooler surface temperatures and slightly lower dewpoints compared to
areas north.
