Climatologically, it is not supposed to snow in South Florida. The laid-back tropics are a region constantly gaining energy from the sun, and with Florida's temperatures moderated by warm water on three sides, snow is unusual even in the northern reaches of the state.

Parts of North Florida were blanketed by snow on Tuesday as a winter storm barreled through the South, resulting in the first-ever blizzard warning along parts of the Gulf Coast in Texas and Louisiana.
