Today in Weather History

On this day, in 2013, our country saw a rather unusual tornado outbreak take place in the northern portion of the Midwest. What do I mean by unusual you may ask? Well, this time of the year, there normally isn’t the proper amount of moisture supplied in the atmosphere for severe thunderstorms, let alone tornadoes, to take place. However, a low pressure system across the plains was the source of high amounts of moisture, with dew points ranging in the mid-60’s. With the combination of this moisture, seasonal abundance of wind shear, and the passage of a cold front, ten tornadoes touched down in a single day in the state of Illinois. We lost three lives because of this, leaving one hundred and forty-two injured.
