San Antonio Weather: Current Conditions and Upcoming Forecast

San Antonio residents are accustomed to a mix of sunshine and occasional storms, but the San Antonio weather pattern this week has been particularly active. Overnight thunderstorms continued through sunrise, keeping the threat of additional flash flooding in place across the metro area. Meteorologists are now monitoring a drying trend that is expected to begin later this morning, offering a brief respite before the next round of moisture arrives.

Recent Storm Activity

Heavy rain has already saturated many neighborhoods. Some areas saw close to six inches of rain within a few hours, prompting numerous flood advisories as water moved through low‑lying streets and drainage channels. The KSAT 12 News Team has been on the scene, providing live updates on the extent of the flooding and the response of local emergency services.

Flash Flooding Threat

Because the ground is still saturated, any additional rainfall could quickly turn into flash flooding. Residents are advised to avoid travel on flooded roads and to stay tuned to local alerts. The National Weather Service has maintained a flash flood watch for the region until the moisture levels begin to decrease.

Short‑Term Forecast Outlook

Early this afternoon, the rain is expected to taper off, giving way to a humid, unsettled atmosphere. Forecast models indicate a high near 90 °F, with a lingering 30 % chance of scattered thunderstorms. Meteorologist David Guerrero of KSAT 12 explains that the lingering moisture in the Gulf will continue to fuel occasional showers, especially after sunset.

Overnight Possibilities

Rain is possible throughout the overnight hours. While the intensity is likely to be lower than earlier in the day, the combination of lingering clouds and nighttime cooling could produce brief, localized downpours. Residents should keep an eye on real‑time radar and be prepared for sudden changes in visibility.

Winter Weather Considerations

Although San Antonio is primarily known for its warm climate, winter storms can still impact the area. Meteorologist Paul Mireles recently answered viewer questions about an upcoming winter system, noting that freezing rain is moving out of the region and that any lingering ice patches are expected to melt within the next 12 hours. This information is crucial for drivers and outdoor workers who may still be dealing with slick surfaces.

What to Expect This Winter

While the current system is weakening, the forecast calls for a brief return to cooler temperatures later this week. Residents should remain vigilant for any advisory updates, especially if temperatures dip below the freezing point, as even a light glaze of ice can create hazardous conditions on bridges and overpasses.
