Daily Weather Brief for December 17, 2025

Today’s weather in Houston brings cooler air, persistent clouds, and light rain as the region settles into a damp midweek pattern. This Daily Weather Brief outlines what you can expect throughout the day, along with safety considerations, wind updates, and an overview of the broader weather setup shaping our conditions.

Cool Temperatures and Widespread Cloud Cover

Temperatures remain mild today, with an afternoon high near 70°F and a morning low around 59°F. Despite the comfortable numbers, skies stay almost completely overcast, with cloudiness near 99%. Because of these thick clouds, temperatures will not move much, even into the evening.

Light rain continues at times, adding up to about 0.09 inches. While rainfall stays gentle, the consistent drizzle may create slick spots on roads, especially during the morning and evening commute.

Wind and Marine Conditions

Winds run near 10 mph from the southeast, with occasional gusts reaching 22 mph. These gusts may cause minor travel disruptions for high-profile vehicles. Although winds are not severe, coastal and boating interests should remain aware of choppy conditions on area waterways.

Because the breeze increases slightly during the afternoon, those spending time outdoors may want a light jacket, especially as the damp air holds steady.

Rain Outlook and Air Quality

Although steady downpours are not expected, light rain lingers off and on through the day. Roads may stay wet late into the evening. Because clouds keep the atmosphere stable, thunderstorms are unlikely.

Air quality remains in a good range, thanks to the moisture and low pollutant levels. Sensitive groups should still monitor real-time conditions, but no widespread issues are anticipated.

What Houston Residents Should Know Today

• Expect a high near 70°F and a low near 59°F.
• Clouds dominate the sky, reducing sunlight for most of the day.
• Light rain continues, but flooding is not a concern.
• Winds increase slightly in the afternoon, with gusts near 22 mph.
• Air quality remains favorable.

Residents commuting early or late should allow extra time due to wet pavement. Because temperatures remain cool, keep a light layer handy throughout the day.

Looking Ahead
