Temperatures and Rain Outlook

Temperatures will range from a morning low near 52°F to an afternoon high around 67°F. Because skies will remain overcast, temperatures are not expected to fluctuate much. Light rain will persist at times, with total precipitation close to 0.06 inches. While this rain amount is modest, it could create slick roads during the morning commute.

By evening, temperatures will settle into the lower 60s. Nighttime conditions will remain cloudy, with no major clearing expected.

Wind and Atmospheric Conditions

Winds will stay light to moderate. Speeds will average around 9 mph from the southeast, with gusts near 20 mph. These gusts may cause brief periods of swaying tree limbs, but no damaging winds are expected. Atmospheric pressure will hold near 1017 mb, which supports the stable but cloudy setup.

Cloud Cover and Visibility

Cloud coverage will reach 99%, keeping sunlight minimal throughout the day. Visibility should remain mostly stable, though early rain showers may reduce clarity during peak traffic hours.

Air Quality and Safety Notes

Air quality should remain in a healthy range, as light onshore flow typically supports good dispersion. Even so, those sensitive to humidity or cool, damp air may want to take precautions. Although rain will be light, drivers should allow extra braking distance on wet streets.

What Houston Residents Should Plan For

• Carry a light rain jacket or umbrella due to on-and-off showers.
• Expect cooler-than-normal temperatures, especially during morning and evening hours.
• Plan for slick roads during early travel.
• Watch for light gusts, but no severe weather is expected.

Conclusion

Tomorrow will bring a cool, gray, and lightly rainy day across Houston. While no hazardous weather is forecast, the combination of wet roads and persistent cloud cover calls for patience during travel. Stay tuned to local updates for any changes as conditions evolve.
