Scattered showers and storms will develop Monday afternoon and evening, which will cool some of us down. There is the potential for a strong to severe storm, or two, to develop, mainly along and north of the I-30 corridor.

This is the area that will be under a MARGINAL risk of severe weather. If a strong storm develops, it could produce hail and gusty winds. Most of the rain and storm activity will start to diminish late this evening as temperatures cool.

The I-30 corridor will have the best chance of rain today, but a downpour or storm can’t be ruled out anywhere.
