Daily Weather Brief for January 21, 2026 – Houston

Today’s Houston weather brings light rain, cool temperatures, and thick cloud cover, creating a damp and gray midweek pattern across Houston. While conditions stay manageable, residents should prepare for wet roads and a cooler feel through the morning and afternoon.

Cooler Air and Light Rain Throughout the Day

Temperatures stay below typical January averages. The morning starts near 62°F and reaches a daytime high around 71°F. Although the warmest readings come in the early afternoon, steady clouds keep conditions feeling cooler. Light rain totals should reach about 0.13 inches, enough to create occasional slick spots but not enough to cause flooding.

Winds arrive from the southeast at about 9 mph, with gusts near 25 mph. While winds are not severe, they may make umbrella use a challenge during brief showers. Cloud coverage remains at 100%, so sunshine stays limited all day.

Evening Outlook and What to Expect Overnight

The evening brings continued drizzle as temperatures ease into the mid-60s. Nighttime lows settle near 64°F, which keeps conditions mild but still damp. Because skies remain cloudy, fog formation is possible in pockets around sunrise on Thursday. Drivers should plan for reduced visibility if fog develops.

Roadway traction may decrease after sunset due to light rain. Therefore, allow extra travel time if you head out late.

Air Quality, Allergens, and Travel Notes

Air quality remains good today. The light precipitation and thicker cloud deck help limit airborne irritants, which benefits residents sensitive to pollen or pollution. Tree and grass allergens stay low as well.

Travelers should monitor flight schedules, as overcast skies and light rain can sometimes slow operations at local airports. However, no major disruptions are expected at this time.
