Houston is waking up Sunday with temperatures around 75 degrees before another steamy afternoon takes over. The high is expected to reach about 94 degrees.

Most of the day should stay mostly sunny, with a 0% chance of precipitation during the Sunday daytime period. Winds should remain light and variable.

Monday Keeps The Heat On

Monday looks much like Sunday, with sunny skies, a high near 95 and another slight chance of afternoon showers or thunderstorms. Overnight temperatures are forecast to fall to about 77 degrees. The hot pattern is expected to continue through the middle of the week, according to the National Weather Service Houston/Galveston.

A Small Cooldown Arrives Later In The Week

Hot conditions are expected to continue through midweek, with conditions becoming slightly less hot later in the week.

There are no watches, warnings or advisories listed for the Houston area. For Sunday and Monday, the practical play is to handle outdoor errands earlier and carry water.
