Keep the jackets and umbrellas handy!

Hope you don’t mind the cold! It’s unseasonably cold and damp to start the weekend, with some impressively late-season snow in the Hill Country.

Here’s what we’ll be monitoring:

A damp and chilly weekend forecast (Copyright 2023 by KSAT - All rights reserved.)


  • Impressively, and as forecast, there was snow in the Hill Country Saturday morning -- in Edwards, Kerr, and Real counties. NO MAJOR IMPACTS are expected in the Hill Country as temperatures are largely above freezing. Any snow will turn back into rain by lunch.
  • Cold, beneficial rain developed around San Antonio.
  • Rain will continue throughout most of Saturday, with showers eventually tapering off by the later afternoon. Highs will only be near 50°.

Side note: You may be wondering — if temperatures here at the surface are above freezing, shouldn’t all of the snowflakes melt before reaching the ground? Believe it or not, a few snowflakes may still be able to exist closer to the surface in those conditions. It all has to do with the vertical profile of temperatures in our atmosphere.

Temperatures in the layers of the atmosphere above our heads will be below freezing (allowing those snowflakes to exist as they fall from the base of the cloud), but the layer of air where we are at the ground will stay above freezing. This above-freezing layer could be so thin, though, that it wouldn’t allow enough time for all of those flakes to completely melt as they fall, but since the temperature of the ground is >32°, whatever hits area roadways should melt on impact.

If you have videos and images of rain or snow, share them with us on KSAT Connect and we may use them online and on-air. You can also download KSAT’s weather app for customized and accurate forecasts.

SUNDAY (3/19)

  • In San Antonio, there will be a few isolated showers in the morning hours with better coverage west toward the border.
  • Another chilly day with a high in the low-50s.


  • The first official day of spring on Monday won’t really feel like it in South Central Texas! Lows in the upper 30s are expected to usher in highs in the upper 40s with another chance for scattered rain.
  • We will start to warm things back up by Tuesday and Wednesday, though, as the humidity makes a return and highs climb into the 60s and 70s. We’ll keep you posted!
