Morning Fog to Make Way for Mild Afternoon Sun in San Antonio

A Gray Start to the Day

San Antonians waking up this Tuesday, February 3, 2026, will likely find the Alamo City draped in a thick layer of patchy fog. This moisture-heavy start to the morning is expected to linger until approximately 9:00 AM, potentially impacting the morning commute with reduced visibility across major thoroughfares like I-10 and Loop 1604. Temperatures at sunrise are hovering in the comfortable mid-to-upper 50s, a significant departure from the freezing conditions seen earlier in the week.

The Afternoon Warm-Up

As the morning progresses, the gray skies are forecast to peel back. Meteorological data indicates a gradual transition from overcast conditions to mostly sunny skies by the early afternoon. Thanks to a strengthening ridge of high pressure, the temperature in San Antonio is set to climb to a pleasant high of 71 degrees Fahrenheit. While a weak cold front is scheduled to track through the region today, it is not expected to bring the biting chill associated with previous January systems. Instead, this front will primarily serve to sweep away the morning humidity and clear the air for the remainder of the day.

Wind Shifts and Rain Chances

Winds will start the day coming from the south at roughly 5 to 10 miles per hour, contributing to the morning’s humid feel. Following the passage of the weak frontal boundary, the wind will shift to the north and north-northeast by the evening. While most of the San Antonio metropolitan area will stay dry, there is a slim 20% to 24% chance of passing showers, particularly for residents located just east of the city. For most, however, the day will be defined by the successful struggle of the sun against the morning cloud deck.

Clearing Skies for Tuesday Night

As the sun sets around 6:13 PM, the cooling effect of the dry northern air will become more apparent. The evening will be marked by partly cloudy to clear skies, making for excellent visibility if you are planning to be outdoors. Temperatures will drop steadily after dusk, eventually reaching a low of approximately 45 to 48 degrees Fahrenheit overnight. This crisp, cool air sets the stage for a bright and sunny Wednesday, continuing the trend of mild winter weather for South Texas.
