Significant Severe T-storm Risk Today. NOAA SPC has much of Minnesota in a "slight risk", with an "enhanced" risk of severe storms, large hail, damaging straight-line winds and isolated tornadoes just north and east of the MSP metro area into central Wisconsin.

A Few Tornadoes? With a warm frontal boundary snaking just north of the metro there may be enough low-level wind shear for a few tornadic, supercell thunderstorms this afternoon and evening; the best chance northeast of the Twin Cities.

Timing the Storms. NOAA's HRRR model develops a squall line into the metro area by mid-afternoon. The future radar prediction above is valid at 2 PM, although I suspect storms may initiate a little later in the afternoon. Stay alert for watches and warnings later today.
