Forecast for Jan 22-23 Severe Weather Outbreak Timeline

A major outbreak of severe weather the night of January 22nd into the morning of January 23rd spawned numerous tornadoes, damaging wind gusts and hail. The storms damaged numerous homes across the South, and 2 people in Alabama were killed. The severe weather setup was identified days in advance, with forecasts becoming more urgent and specific leading up to the event. Below is a timeline of the forecasts, watches and warnings indicating dangerous weather was on the way, but according the lead story on ABC News Monday evening, the following events might as well have never happened. Here is a clip from ABC world news, in which the story says the tornadoes were a "surprise" and struck with "no warning"




Here is what actually happened:

1:30 PM Friday January 20th - The Storm Prediction Center in Norman Oklahoma issues an updated severe weather outlook for Sunday into Sunday night. A large portion of the South is upgraded to a SLIGHT risk for severe storms. Meteorologists, some of which of have already been discussing the possibility for severe weather a couple days prior, communicate the possibility of strong storms. 



11:30 AM Saturday January 21st - The Storm Prediction Center indicates the possibility of a large scale severe weather outbreak with the likelihood of tornadoes, some of which could be strong. The percentage chance of severe weather within 25 miles of a given point is increased to 30% within the red area. The black outline indicates an enhanced threat of significant severe weather, including EF2+ intensity tornadoes. Local TV meteorologists actively discuss the possibility of a tornado outbreak in this region on TV, radio and Internet. Storm spotters plan to activate for Sunday evening into Monday morning.

Parts of Arkansas, Mississippi, Alabama and Tennessee are included in a significant risk area for tornadoes. The red area below indicates a 15% chance of a tornado within 25 miles of a given point.

Personally, I would like to thank The Storm Prediction Center, the employees of the local National Weather Service offices, broadcast meteorologists, storm spotters, bloggers and all the support staff across the Southeast and Mid-South regions for their work and dedication leading up to and throughout the event. I am 100 percent convinced that based on all the damage that occurred, the timely warnings and information available to the public prevented numerous injuries and saved lives. I believe at least one national media outlet needs to give credit where credit is due, and apologize to all those it belittled.
