January 2023 will be remembered more for its tornadoes and severe weather than for more traditional winter weather like snow and ice for everyone east of the Rockies. January is not typically a severe weather month, but this year was a big one.

The Storm Prediction Center reports we had 168 preliminary reports of tornadoes this month, most of which were across the southern states.

The number will go down slightly once all the reports have been surveyed, but it is still staggering when you consider the average number of January tornadoes is around 50, putting this year’s total at more than triple the average.

Much of the South and Southeast ran five to 10 degrees above normal for the month of January, allowing Gulf moisture to spread northward, resulting in more instability and ripe conditions for tornado development.

This is how a thunderstorm produces a tornado

The instability helped produce tornadoes across 16 states this month alone.

The January 12 outbreak produced a whopping 70 tornado reports across seven states. Most notably was the tornado that ripped through Selma, Alabama killing at least six people and devastating the historic downtown.

Houston is experiencing its second-warmest…
