Winter Wonderland

Sunday night into Monday, San Antonio and the surrounding area saw 3-6 inches of snowfall -- the most the area has seen since 1985. If you have snow pictures, please feel free to drop them in the “pins” section of the KSAT Weather Authority App.

Some snow totals so far:

  • New Braunfels: 5 inches
  • Geronimo: 5 inches
  • Castle Hills: 4.5 inches
  • Bulverde: 4.5 inches
  • Hollywood Park: 4.0

Dangerous Cold Monday

The wintry precipitation from Sunday night has come to an end. However, wind chill values will range from 0° to -15° Monday morning. So, if you plan to enjoy the snow, please wear several layers and protect your body from hypothermia.

Wind chill values are well below 0°F Monday morning

Travel Impacts

Even though wintry precipitation will end by midday Monday, we won’t be able to warm above freezing until sometime Tuesday afternoon. Because of this, any precipitation on the ground will not be able to melt much before the Tuesday morning commute. So, please be prepared for travel hazards and delays on both Monday and Tuesday mornings. We’re also monitoring the likelihood of another round of wintry weather Tuesday night and early Wednesday.

Morning flights at the San Antonio International Airport have been canceled due to the inclement weather. Learn more here.

Many school districts have announced plans to cancel school or go remote-only on Monday. Click here for the latest.

The city of San Antonio and WellMed have both decided to reschedule vaccination appointments on Monday.

Cold Weather Preparations

While the idea of winter weather in Texas can be exciting, it can also be dangerous if you’re not prepared. Make your preparations sooner rather than later. Here are some things to keep in mind:

  • Remember the 4 P’s: People, Pets, Plants, and Pipes
    • Check on the elderly and those who may not have a heat source
    • Make sure pets are cared for by providing warm shelter and food
    • Cover any outdoor plants and sensitive vegetation
    • Wrap outdoor plumbing pipes - especially if you live in a rural area
  • Closely monitor the weather if you have travel plans and stay home if you can
