FORECAST

TONIGHT

Light sprinkles will gradually transition to light sleet this evening, then a mix of sleet and snowflakes overnight. But you won’t be able to make a snowman or have a snowball fight 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 south of I-10 and east of I-37.

  • Accumulation of any snow and sleet will be less than an inch
  • Ice accumulations will be LIGHT – 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. Slicks spots may exist 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 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.
