Severe Threat Update
Doppler Radar Update: 1:36 PM. Doppler out of MPX shows strong/severe storms tracking across southern MN, small, marble-size hail west of Shakopee, but the most severe storms are near the Iowa border, where 60 mph+ winds and some ping pong size hail is likely through the afternoon hours. In this kind of an environment, with sufficient wind shear, instability and low-level moisture, an isolated tornado can't be ruled out. The greatest risk of tornadoes appears to be farther south, over Iowa, under a "moderate" risk from SPC.
