TALLAHASSEE, Fl. (WTXL) -- Every Tuesday on WTXL Sunrise, you'll be able to have one of your own weather questions answered by Meteorologist Alex Cordero.

This week, our question comes from Ashley Southern, from Valdosta, Georgia.

Her question: "Why are there two severe weather seasons?"

There is no "official" start, like there is with the Atlantic Hurricane Season.

The two severe weather seasons occur during late fall and late winter//early spring. This is typically the time when upper level winds bring strong low pressure systems and cold fronts to our doorstep. The severe weather that these fronts can bring can range from straight line winds, to flash floods, and even tornadoes.

Cold fronts are able to drop further to the south during this period, impacting the southeastern U.S. They normally carry the ingredients needed to form severe storms: Moisture, instability, warmth, and strong upper level winds.

As the months progress, these fronts lose the frequency of how far south they travel. For instance, during the Summer, the jet stream retreats north and cold fronts stay north.

This means that all of the severe ingredients move away from us and we have a lower severe chance.

But, don't be fooled. Severe weather can occur at any time during the year.
