The tornado outbreak, that occurred on Sunday, November 17, 2013, was a rare event. When we talk about severe weather in November, the Midwest and Great Lakes don’t typically come to mind right away. Historically, tornadoes in November develop in the states along the Gulf of Mexico (see map below).
The maps below(click to enlarge) are the “Day 2″ forecast. The outlook map on the bottom right is for Sunday and was issued Saturday. It is very rare to have a moderate risk area as for north as it was. The map on the bottom left shows you the amount of times a moderate risk outlook is issued for “Day 2″ in November. Notice most of them are in the southeast matching up with the map above.
The map below shows two things. The first one is the severe weather outlook for Day 1. The outlook issued Sunday morning. The dots on the map indicate where all of the severe weather was. The red dots are the tornado reports and fall pretty much into high risk area in Illinois and Indiana.
So I mentioned how rare moderate outlooks are in November now lets take a look the only two high risk outlooks issued in November since 1998. (see map below)
As of this post the preliminary reports are that 76 tornadoes occurred in this outbreak. The two images below are from the tornado that went through Washington, IL. At this time is has been rated an EF 4. Click here for more information about the Washington, IL tornado.

Despite all of the tornadoes on Sunday, we are still way below normal when it comes to tornadoes this year across the country. The total is now up to 886. The average, since 2005, is about 1,500 tornadoes. (see chart below)
