Areas affected...central MN

Concerning...Severe potential...Watch likely=20

Valid 161825Z - 162030Z

Probability of Watch Issuance...80 percent

SUMMARY...Thunderstorms should intensify ahead of an eastward-moving
surface cyclone, starting in west-central Minnesota. A few
supercells capable of large hail, damaging winds, and a couple
tornadoes are possible. A watch will likely be needed with
uncertainty on southern extent of the threat.

DISCUSSION...Initial low-topped convection has increased near the
southeast ND/west-central MN border area in vicinity of a surface
cyclone. A corridor of greater insolation persists ahead of this low
into the Brainerd Lakes area, northwest of regenerative elevated
convection across east-central MN to northeast IA. This should yield
further low-level destabilization and increasing moderate buoyancy
into late afternoon. While 12Z CAMs largely underplayed the morning
elevated convection, the RRFS has consistently signaled the
surface-based convection may remain largely confined to near the
surface low/warm front across central MN. Low-level shear is modest,
but a belt of stronger 700-mb winds attendant to the shortwave
impulse should support a few supercells in an emerging cluster that
spreads east into early evening.
