Dangerous heat and humidity will build back in Saturday and Sunday. Highs in the 90s and dew points in the 70s will send heat indices into the 100 to 108 degree range each day.
There is growing potential for severe thunderstorms over eastern MN into WI late Saturday and across all of MN and WI late Sunday. The main hazards are large hail and damaging winds, although a tornado or two cannot be ruled out.
