Cold Fronts don't steer storms towards Florida. It all depends on the location of the storm the ridge and the front. Wilma being a perfect example.

Storms are always wanting to trend to the right due to the Coriolis effect explained below. Cold fronts (troughs) create weakness in Highs (ridges) allowing storms to escape poleward. Picture mountain ranges upside down with valleys in between them would be a simplistic way of visualizing the atmosphere.

Coriolis Effect:
Coriolis effect is an inertial force described by the 19th-century French engineer-mathematician Gustave-Gaspard Coriolis in 1835. Coriolis showed that, if the ordinary Newtonian laws of motion of bodies are to be used in a rotating frame of reference, an inertial force--acting to the right of the direction of body motion for counterclockwise rotation of the reference frame or to the left for clockwise rotation--must be included in the equations of motion.
