While much of the country will be impacted by wintry weather, this incredibly dynamic system has the potential to bring an additional hazard to parts of the South: severe thunderstorms!

Out ahead of the system, Florida on Sunday could be feeling record-breaking heat. This warm airmass will get pulled north out ahead of the advancing cold front. Increasing instability and strong jetstream dynamics will fuel a growing thunderstorm risk into the afternoon hours.
Heavy rain will be falling as early as dawn on Sunday, but as instability builds during the day, storms are expected to strengthen as they move east along the cold front. While weakening somewhat into the overnight hours, heavy downpours and strong gusty winds will remain possible. Later Monday morning, the cold front is expected to clear the Southeast coast with precipitation chances coming to an end.

Heavy rainfall will lead to impressive totals, especially across Mississippi into northern Alabama. A flash flooding threat can't be ruled out!
