Tonight, fair skies a light breeze warm and stuffy with a low near 80 and a heat index in the 90's.
Tuesday will be breezy and blazing hot with sunny skies and a high of 98.

Wednesday a little more wind, very humid and sweltering heat with a high of 97.
Saharan dust will arrive from Africa on Thursday adding more haze to the south Texas skies.

Stay cool.
