Areas affected...Southwestern-Central MN

Concerning...Severe Thunderstorm Watch 515...

Valid 100420Z - 100615Z

The severe weather threat for Severe Thunderstorm Watch 515
continues.

SUMMARY...Strong convection will continue along a corridor from
southwestern through central MN. Locally damaging winds are the
primary risk for the next few hours.

DISCUSSION...Earlier MCS that formed over eastern SD has advanced
downstream and weakened somewhat as surface low is now lifting north
across southeast ND. However, a southwest-northeast corridor of
strong storms continues across MN, strongly influenced by low-level
warm advection in association with 40-50kt LLJ. Latest
satellite/radar data depict a well-defined upper vort over Hand
County SD approaching the southwestern flank of MN convection. This
feature will likely contribute to the maintenance of thunderstorm
activity across the upper MS Valley during the pre-dawn hours. Given
the observed shear within the warm advection zone, there is some
concern for a few strong/locally severe storms. While this activity
has not been particularly productive over the last few hours, some
severe threat will linger due to the shear/forcing.
