Houston is starting Saturday with clear skies and temperatures around 79 degrees, but the calm will not last all day. The city is headed for a high near 94, followed by a chance of afternoon showers and thunderstorms. Sunday and Monday look wetter, while the heat remains firmly in charge.
Saturday Starts Sunny, Then Storms Bubble Up
Most of Saturday should stay mostly sunny through midday, with temperatures climbing into the upper 80s by late morning and the low 90s during the afternoon. A 30% chance of showers and thunderstorms arrives after 1 p.m., with southeast winds between 0 and 10 mph. The National Weather Service expects the most activity during the daytime as the Gulf breeze moves inland.
Rain chances ease Saturday evening to about 20%, and the overnight low should settle near 79 degrees under mostly clear skies. Sunday begins with a slight chance of morning showers before storm chances increase later in the day. The forecast calls for a high near 93 and heat-index values as high as 101.
Sunday And Monday Bring Better Rain Chances
Sunday and Monday are the most unsettled part of the forecast, with a 40% chance of showers and thunderstorms each day. Monday will be somewhat cooler, with a high near 91, but the humidity will keep outdoor conditions uncomfortable. Forecasters say scattered seabreeze storms may continue daily through early next week, with heat-index values generally ranging from 101 to 108 degrees.
The setup is familiar to Houston in August, but this round brings a more noticeable rain window than the recent mostly-sunny stretches. An earlier Hoodline forecast tracked the same basic combination of sticky heat and pop-up storms, while the current outlook puts the best storm chances on Sunday and Monday.
Hotter And Drier Again By Midweek
Rain chances fall sharply Tuesday, when Houston should see mostly sunny skies and a high near 94. Wednesday is expected to reach about 95, followed by sunny highs near 96 Thursday and Friday. Overnight lows remain warm, ranging from 79 to 81 degrees, so there will be little relief after sunset.
For outdoor plans, the morning will generally offer the best conditions, while afternoon activities may need flexibility for both heat and sudden downpours. Drink water regularly, take breaks in shade or air conditioning, and keep an eye on updated forecasts if thunderstorms develop nearby. No watches or warnings were listed with the current forecast.
