The Houston weather forecast is turning wetter at the start of the week, with humidity and rain expected to return across south-east Texas from Monday after a warm and dry Sunday.
Conditions should remain settled through Sunday evening and overnight, with mild temperatures and relatively low humidity providing a brief respite before moisture builds again.
Houston rain forecast turns more unsettled
Scattered showers and thunderstorms are expected to develop from Monday and continue through Wednesday evening. Tuesday is likely to bring the most widespread coverage, although the rain is forecast to remain locally focused rather than continuous across the region.
The National Weather Service’s Houston-Galveston office is also forecasting isolated rain chances each day next week as winds draw more moisture inland. Its latest outlook puts Houston’s chance of rain at about 30 per cent on Monday, rising to 60 per cent on Tuesday.

Temperatures will remain well above typical autumn levels at first, with highs around 91F (33C) in Houston on Monday and 92F (33C) on Tuesday, according to the weather service. Coastal areas including Galveston are expected to be cooler, with highs in the mid-80s.

Cold front could bring cooler weather
Forecasters are also watching a cold front expected to approach the region on Friday, October 16, or Friday evening. The system is expected to bring drier air and a noticeable fall change to south-east Texas, although its strength and exact timing remain uncertain.
Some forecast models indicate that daytime temperatures could fall into the 60s and 70s after the front passes, while other guidance keeps highs in the 80s. The National Weather Service says the most consistent signal is for lower humidity and cooler, drier conditions over the following weekend.

Before that change arrives, humidity and overnight temperatures are expected to climb, leaving the Houston area with several unsettled and increasingly muggy days.
