Moderate Risk for Severe Weather MN, IA, WI

 The Storm Prediction Center has upgraded portions of Minnesota, Iowa, and Wisconsin to a MODERATE Risk for severe weather including tornadoes, some of which could be strong today.

An Enhanced Risk includes portions of Nebraska, Iowa, Minnesota, and Wisconsin.

This is starting to be concerning as this is December, but it's starting to feel a lot like May. This is a pattern that we do not want to keep around. 


Here we can see a 10% hatched significant threat for tornadoes in the yellow hatched areas across a good portion of Iowa, SE Minnesota, and W Wisconsin. 5% chance for tornadoes in brown and 2% in green.


Damaging winds are of a significant threat today inside and outside of storms, winds  could reach up to 60-75 miles per hour. With embedded gusts reaching in the 80-100 mile per hour range with storms. 45% hatched significant threat in pink, 30% in red, 15% in yellow, and 5% in brown.


The hail threat is low at 5% in brown, hail events will be more isolated. 


The big story here is the winds and the Storm Prediction Center has noted that a strong tornado or two could occur with this system. These tornadoes would likely been nocturnal, so please have a way to be alerted and woken up should you experience severe weather.

A high wind warning has been issued for a large swath of states in the Yellow


A tornado watch has been issued
