FORECAST

TONIGHT

A light glaze is forming on some elevated surfaces such as street signs, parked vehicles, decks, etc. and will mix with sleet and snowflakes through the night. But you won’t be able to make a snowman or even make much of a snowball in the morning because accumulations will be minimal (less than 1″). Precipitation will peak between midnight and 5am Tuesday, then the sun comes out by 10am causing a rapid melting.

*NOTE: Contrary to conventional thinking, conditions will actually be better across the Hill Country this go around. The higher moisture availability which could lead to slightly higher accumulations will be positioned between I-10 and I-37.

  • Accumulation of any snow and sleet will be less than an inch
  • Glaze ice accumulations will be LIGHT and on elevated surfaces- less than .10″
  • Still, even a small amount of ice can make for slick spots, mainly on bridges and overpasses

TUESDAY MORNING

Light snow and sleet will come to an end by sunrise tomorrow. However, watch for slicks spots on some of the bridges and overpasses and even less-traveled roads until about 10am. Accumulations of sleet (ice pellets) and snow should be less than an inch and mostly just a dusting/light coating on the grass, dirt, gravel driveways, decks, parked vehicles, etc. Again, sunshine will take over around 10am and cause a rapid melt.

Sunshine will allow temperatures to reach 40° in the afternoon, but then a hard freeze is upon us Tuesday night/Wednesday morning with lows near 20°, which is the coldest yet this winter.

Light wintry mix until sunrise Tuesday in South-Central Texas.

REST OF THE WEEK

Morning freezes are expected through Friday, but afternoons will get warmer with highs in the 50s by Thursday and Friday, then into the 60s over the weekend.

San Antonio forecast as of 7pm 1/20/25.
