Drier air is moving into the region, bringing mild afternoons and cooler nights to start the week. Humidity and rain chances could climb again later on, while a stronger cold front may be possible by mid-October.
Monday through Wednesday will be mostly dry, with afternoon highs in the 80s and lower humidity. A cool, dry air mass should make for more comfortable afternoons than Houston has seen recently.
Overnight lows will dip into the 60s outside the city and away from the coast. Houston’s urban heat island may keep temperatures a little higher, with some neighborhoods staying in the low 70s.
The cooler mornings will be a welcome change, though they don’t signal a lasting shift to fall weather. Afternoon temperatures will remain seasonably warm, and the forecast could turn more unsettled as the week goes on.
The dry air may begin to fade later this week as a weather system approaches from the west and the high-pressure system over the Plains shifts east. That could allow moisture to return from the Gulf of Mexico, raising humidity and bringing a chance of showers and thunderstorms.
The exact timing and coverage of rain remain uncertain. For now, the main takeaway is that Houston’s dry stretch may not last through the end of the week. Check back for updates as the weather pattern takes shape.
