This holiday weekend, a cold front will move across Texas and stall, bringing chances for scattered showers and storms each day. These storms may produce gusty winds, frequent lightning and brief, heavy downpours.

When thunder roars, go indoors.

Because of clouds and rain around, high temperatures will be slightly below normal in the upper 80s to low 90s.

If you're waiting to set fireworks off when it gets dark, sunset to is a little after 8:30 p.m. Have fun, but remember to stay safe.
