Cool Morning Start, Mild Afternoon Ahead

Temperatures start near 38°F at sunrise, so a light jacket will help early commuters. As the morning progresses, the air warms slowly. Eventually, afternoon highs reach about 54°F, which is several degrees below Houston's typical mid-December norm.

Because the day stays dry and clouds remain limited, sunshine should feel warm when winds ease. Even so, the air may carry a slight chill due to seasonal high pressure.

Light Winds and Mostly Clear Skies

Winds stay light through most of the day, blowing from the northeast near 10 mph. Occasional gusts may reach 15 mph, but conditions remain manageable for outdoor plans. The sky stays mostly clear with only about 24% cloud cover, which allows sunlight to dominate the afternoon.

This stable pattern results from a strong high-pressure system hovering over the region. Because of this system, the area avoids rain, fog, and humid air intrusions.

Evening and Overnight Outlook

Tomorrow evening brings temperatures near 53°F, which feels crisp but comfortable for holiday errands or outdoor gatherings. As night settles in, readings fall toward 49°F. The air stays clear and calm overnight, offering ideal conditions for stargazing.

Although temperatures remain cool, no frost is expected within the city limits. Suburbs may see localized chilly spots, especially in low-lying areas.

Air Quality, Allergens, and Other Local Factors

High pressure usually supports better air quality, and tomorrow looks no different. With dry air and light winds, particulate levels should stay low. Sensitive groups can expect an easy breathing day.

Tree and grass pollen remain low, and mold counts should drop due to the absence of moisture. Because of this, allergy symptoms should remain minor for most residents.

What Houston Residents Should Prepare For

• Cool morning near 38°F, warming to mid-50s by mid-afternoon.
• Dry conditions with few clouds and plenty of sun.
• Light northeast wind around 10 mph with occasional 15 mph gusts.
• Comfortable evening temperatures in the low 50s.

Despite the cooler air, tomorrow offers excellent conditions for shoppers, outdoor exercisers, and families planning holiday outings. Roads stay dry, airports benefit from stable weather, and no severe threats appear on the horizon.
