A very warm and moist air mass developed over Central Alabama on Monday, December 16th. Afternoon temperatures warmed into the lower and middle 70s, which was 15 to 20 degrees above normal for the middle of December. A surface low tracked north of Alabama Monday night and pushed a strong cold across the state. Several bands of strong to severe storms developed across Mississippi during the afternoon and moved into west Alabama that evening.
