Areas affected...Southeast MN into west-central WI

Concerning...Severe Thunderstorm Watch 641...

Valid 020708Z - 020845Z

The severe weather threat for Severe Thunderstorm Watch 641
continues.

SUMMARY...A threat for severe gusts will continue through the early
morning with an ongoing MCS.

DISCUSSION...A compact but long-lived and well-organized MCS is
moving across southeast MN early this morning. This MCS recently
produced gusts of 60-70 mph in the Rochester, MN area, and
relatively strong inbound velocities continue to be observed from
the KARX radar. Given its current organization and favorable
deep-layer shear noted from the KARX VWP, this MCS will likely
continue to pose a short-term threat for severe gusts as it
approaches west-central WI. With time, this MCS will begin to
encounter a less favorable thermodynamic environment, as it moves
into a region increasingly influenced by outflow from downstream
convection. As a result, the longevity of severe-wind potential is
uncertain, but at least some threat for wind damage with the ongoing
MCS may eventually reach eastern portions of WW 641.
