Severe Weather Setup

An area of low pressure will track eastward along the Gulf Coast Tuesday into Wednesday. This low's trailing cold front will interact with Gulf of Mexico moisture surging up from the south and act as a lifting mechanism for thunderstorms to develop.

The speed at which this low-pressure system slides east will dictate the timing of the severe threat. Also, the position of a warm front will determine how far north severe weather may extend.
