Showers and thunderstorms will come in the afternoon through Saturday, but will quickly wane.
"With the only trigger being daytime heating instability, they will not be widespread or last very long," AccuWeather.com Meteorologist Stephen Travis said.
The majority of storms will be confined to the afternoon and evening. Drier air will push into north-central Texas starting on Sunday and lingering into Tuesday.
It will turn very warm and humid as well.
Temperatures through Saturday will rise into the middle to upper 80s in the afternoon, which is near average, Travis said.
"It will be seasonably mild at night with overnight lows in the upper 60s to low 70s," he said.
It will also turn increasingly humid with dew points rising into the middle and upper 60s by this weekend.
"The most oppressive days will be Sunday through Tuesday with afternoon highs in the lower 90s and overnight lows in the middle 70s," Travis added.
