SUNDAY EVENING UPDATE: Not much change in thinking; a high impact line of severe thunderstorms will race through Alabama late tonight into the pre-dawn hours tomorrow. New SPC graphics are attached. Here are the key messages. *The line of storms should enter the northwest corner of the state around 9 p.m... and it should clear the southeast corner by 6-7 a.m. tomorrow. *Wind fields with this system are very strong, and wind gusts of 50-70 mph are likely along the line. This will likely bring many power outages, perhaps major ones. Be ready to be without power for a day or two. *A few tornadoes are possible within the line. Models continue to suggest storms will become more cellular in nature after 3 a.m. across SE Alabama, with a higher potential of tornadoes there. Perhaps a few strong tornadoes (EF-2 or higher). *There is a decent chance I will advise you to treat severe thunderstorm warnings like tornado warnings tonight. Be sure you have a reliable way of getting warnings (never a siren!), and have a good action plan. Know the safe place in your home, and have helmets there for everyone. *I would not want to be in a mobile home or camper when these storms move through. Know the location of the nearest shelter, and how to get there quickly. Have transportation available. *Very cold air will roll into Alabama tomorrow, and a few snow flurries or snow showers are possible. No impact is expected with temperatures above freezing (generally in the mid to upper 30s). *Have the Alabama Weather Network app on your TV, phone, and tablet. Follow AWN on YouTube. Watch the coverage tonight; we handle the entire state with a team of experienced meteorologists in the studio, and in the field with dash cams and drones. We have resources unlike anyone else. We will most likely go live about 9:00, or about 30 minutes before the storms move into the northwest corner of the state.

HIGH IMPACT SEVERE WEATHER THREAT TONIGHT: A dynamic weather system with strong wind fields will push a line of severe thunderstorms through Alabama late tonight into the pre-dawn hours tomorrow. SPC maintains a level 3/5 "enhanced risk" for much of North and West Alabama, and they have introduced a level 3/5 risk for Southeast Alabama as well. Here are the key messages... *The line of storms will enter the northwest corner of the state around 9-10 p.m... and will move out of the southeast corner around 6-7 a.m. tomorrow. *Damaging winds are likely along the line. In some cases wind gusts could exceed 70 mph. Expect significant, potentially widespread power outages. *A few isolated tornadoes are possible within the line. After 3:00 a.m... high resolution models suggest supercell storms will form across Southeast Alabama with a much higher tornado potential. A strong tornado or two (EF-2 or higher) will be possible from 3-6 a.m. *Tonight most likely I will advise you to treat a severe thunderstorm like a tornado warning. Be in a position to hear warnings, and have a plan. Helmets for everyone; if a tree comes crashing down through your house, this could save your life. *I would not want to be in a mobile home when this line comes through. Know the location of the nearest shelter and how to get there quickly. Have transportation arranged. *Much colder air will follow the storms, and snow flurries/snow showers are likely over the northern half of the state tomorrow. Temperatures will be in the mid to upper 30s and we expect no impact. *A freeze is likely pretty much statewide Tuesday morning with lows mostly in the 20s. Another freeze is likely early Wednesday morning over the northern half of the state. *Get the Alabama Weather Network app on your TV, phone, and tablet so you can watch our live coverage tonight; we have the entire state covered with a large team of meteorologists in the studio and in the field with dash cams and drones.
