SATURDAY: Attached to this post is the Significant Tornado Parameter valid Saturday evening at 7p CT (3km NAM). The STP is a composite index that shows areas were tornado formation is likely. Values are extremely elevated over much of Alabama at that hour (max 15.5)
Parameters continued to favor the potential for a few violent, long track tornadoes across Alabama Saturday afternoon and Saturday night. The window for severe storms with this second round is from roughly noon Saturday until 3a CT Sunday. We might be able to narrow that window down a bit on future updates. 
The first round will come from roughly 10p CT tomorrow until 8a CT Saturday. A few tornadoes are possible at that time as well. But the main event will come later in the day into Saturday night. 
KEY MESSAGES
*Our goal for any severe weather event in Alabama is no loss of life, and no serious injuries. It takes us all working together to make that happen. Everyone must have a reliable way of hearing warnings. Never, ever an outdoor siren. Never. A NOAA Weather Radio should be in every Alabama home and business. On your phone, have WEA (Wireless Emergency Alerts) enabled (look under notifications and be sure "emergency alerts" are active), and have the 33/40 weather app installed.
*In your safe place, have helmets for everyone, including adults. Most serious injuries in tornadoes involve blunt force trauma above the shoulders.
*If you live in a mobile home, know the location of the nearest shelter, or business open 24/7 that can serve as a shelter. Have transportation arranged so you can get there quickly.
*If you are reading this, you pay attention to weather. Understand many people don’t keep up with the weather, so you can be a hero during the severe weather event. Let them know this is a high end threat. During the event, if you have a friend or loved one in a tornado warning polygon, call or text them to let them know of the immediate danger. You can play a huge role in saving lives.
*Subscribe to the James Spann and ABC 33/40 YouTube channels so you can watch our live coverage. We are thankful for the out of state YouTubers who do long form severe weather coverage, but to be truly successful in reaching people and communicating warnings in high end severe weather events like this, you have to understand the people, culture, geography, and microclimate of the region impacted.
*We don't share any of this to scare people. But strong wording is necessary on occasion, and this is one of those times. Get the warnings, have a good plan, and we get through this together.
Conflict in a marriage is inevitable. They're opportunities to learn and grow - but only if you fight well, and doing it while you're flooded is not going to work.
The state of emergency for 37 counties ahead of this week’s winter weather is now in effect.
I encourage Alabamians to make any needed preparations today. If you are in an impacted area and do not have to be on the road, try to avoid it. Stay weather aware. #alpolitics
