Severe storms are likely, and the significant severe weather risk will be increasing into the night for damaging winds, large hail and the potential for some strong tornadoes.

AccuWeather said a system moving across the US could become the biggest severe weather and tornado event of the year so far.

National Weather Service said confidence continues to increase about the possibility of severe weather this weekend in Alabama. All modes of severe weather will be on the table, including tornadoes, damaging winds and heavy rain.
