Roughly two dozen reports of tornadoes were received by the Storm Prediction Center from four states Tuesday into early Wednesday in what was likely the most active day for tornadoes in the U.S. in just over three months.

Damage surveys by National Weather Service meteorologists will firm up actual tornado counts and paths. So far, 19 tornadoes have been confirmed in four states (Tennessee, Alabama, Louisiana, and Mississippi).

Severe Weather Recap

Among the over 100 reports of severe weather received by NOAA's Storm Prediction Center from Tuesday and early Wednesday, there were roughly 22 reports of tornadoes from northern Louisiana to central and eastern Mississippi, northern Alabama and southern Tennessee.
So far, 1-2 EF3 tornadoes, five EF2 tornadoes, nine EF1 tornadoes, one EF0 tornado and two unrated tornadoes have been confirmed by the National Weather Service.
One of those tornadoes in far northeast Alabama's Jackson County around midnight turned deadly.
This was the nation's first deadly tornado in over six months, ending the third longest tornado death-free streak on record in the U.S. since 1950, according to The Weather Channel severe weather expert, Dr. Greg Forbes.
Local NWS offices issued over 120 tornado warnings from Tuesday afternoon through early Wednesday morning.
Trees and power poles were knocked down on Tuesday afternoon by an EF1 tornado in Scott County, MS. A EF1 tornado also destroyed 4 homes in Winston County, MS. Damage was also reported in Aberdeen, MS. A tornado was spotted near Columbus, MS.
A confirmed EF1 tornado hit near Tullahoma in Coffee County, Tennessee. The storm blew over trees and caused roads to be impassible. Power lines were also downed.
By the time surveys are completed, this may be the most number of tornadoes in the U.S. in any 24-hour period since the freak Indiana/Ohio tornado event on August 24, 2016.
There were several reports of tornadoes Monday afternoon, as well, including at least nine in Iowa and one in Louisiana. No significant damage has been reported, however.

Sunday, there were four reports of brief tornadoes in south-central Nebraska. Fortunately, no reports of damage have been received from these brief tornadoes.

Slow 'Second' Season of Severe Weather, So Far

The second half of October and, especially, November can often be a "second" season for tornadoes and severe thunderstorms, particularly in parts of the South. That hadn't been the case so far this year, however, through Thanksgiving week.
Prior to Monday, we hadn't seen a single day with at least 50 reports of severe weather in the U.S. since October 6, when at least eight tornadoes were spawned in Kansas.
It's been over 7 weeks since we had a day with over 50 reports in the U.S. Today could snap that streak. http://wxch.nl/2gnjeND 

So far, 2016 has featured a below-average number of tornadoes. Through three weeks of November, the U.S. tornado count for the year-to-date was 24 percent below average.
