3rd Day in a Row of Major Tornado/Severe Thunderstorm Threat in Midwest

Today's forecast is fairly complicated, so I'll break it down by element. 

Tornado Risk
This is my forecast of the tornado risk. The red area has a high risk of tornadoes. This includes Appleton, Stevens Point, and Wisconsin Dells.

The yellow area is an enhanced risk of tornadoes. The brown areas represent a significant risk. If you live in the southeast half of Wisconsin, it is vital you keep track of the weather the rest of the day! Tornadoes are likely!

Damaging Wind Risk
This and hail are SPC's forecasts. The hatched area is where wind gusts of 75 mph or stronger are forecast to occur. In other areas, the gusts are forecast to be between 58 and 74 mph. This will cause additional power failures in a region already hard hit (below). This means, with the additional outages, some people will be without power for days. The colors represent the relative probabilities:
  • Red has an enhanced risk (1/3 chance within 25 mi of a given point)
  • Yellow has a significant risk. 
Power Failures as of 11:30am CDT

Large Hail Risk
Same probability colors as winds. Here the hatching is a forecast of hail larger than 2" in diameter. The yellow area is where 1-2" hail is forecasted to occur.
