FIRST WARNING: 80 degrees Wednesday; sleet/snow possible Thursday

Forecast

AUSTIN (KXAN) — An afternoon warming trend is underway with high temperatures forecast to rise into the 70s Tuesday and near 80 degrees on Wednesday; but the most extended cold snap of winter thus far arrives Thursday with the potential of light rain mixing with sleet, snow and freezing rain.

A continued southerly flow will warm overnight lows and daytime highs through Wednesday afternoon. Mostly clear skies continue each day with plenty of sunshine making it wonderful weather for outdoor activities.

Forecast temperatures Wednesday afternoon

We are tracking a strong Arctic cold front setting up over Canada, forecast to surge into Central Texas on Wednesday evening. Behind the front, temperatures fall from near 80 degrees Wednesday afternoon into the 20s Thursday morning with strong, gusty winds dropping wind chills even further.

On Thursday, our best computer models are consistently forecasting light rain showers developing early, immediately beginning to mix with sleet, freezing rain and even light snow. While it is impossible to determine exact details on location, precipitation amounts, and roadway impacts this far out, it is certainly possible that we see bridge/overpass icing and light accumulations of snow/sleet on grassy surfaces.

While the potential of winter weather impacts may bring February 2021 to mind, this system will be different in several important ways. Precipitation will be lighter, nighttime temperatures will not be as ‘pipe-bursting’ cold, and daytime highs will warm above freezing both Thursday and Friday, giving roadways a chance to improve.
