Immediate Weather Alert: Storms and Flash Flooding in San Antonio

If you are waking up to the sound of thunder and heavy rainfall, you aren’t alone. San Antonio weather is currently experiencing a volatile period, with scattered storms sweeping through the region. A Flash Flood Warning is currently in effect, as some areas have already reported up to 2.5 inches of rain.

Meteorologists warn that this activity is expected to persist through sunrise. If you are heading out early Saturday morning, please exercise extreme caution on the roads and stay tuned to local alerts.

⚠️ Safety Tip: Never drive through flooded roadways. “Turn around, don’t drown” is the golden rule during South Texas flash flood events.

Weekend Forecast: Umbrellas and Humidity

While the weekend won’t be a total washout, you’ll definitely want to keep an umbrella within reach. Here is what you can expect for the next couple of days:

  • Saturday: Expect scattered, pop-up showers throughout the day. While the rain and cloud cover will provide a temporary reprieve from the sun, the atmosphere will remain warm and steamy.
  • Heat Index: Be prepared for oppressive humidity, with heat index values climbing between 100–105°F in several spots.
  • Sunday (Father’s Day): Good news for those planning outdoor celebrations! Drier air is expected to move in, ending the rain chances and bringing more sunshine for Father’s Day.

Looking Ahead: The Return of the South Texas Heat

Don’t get too comfortable with the rain-induced cooling. The extended forecast indicates that heat and humidity will build back up early next week. Most conditions will remain dry, but the typical South Texas summer intensity will return in full force.

To stay updated with real-time meteorological data and official warnings, we recommend monitoring the National Weather Service (NWS) for the most accurate and timely safety information.
