A Winter Storm Warning is in effect for portions of South-Central Texas from Saturday morning through Sunday morning. An Arctic cold front arrives late Friday night, plunging temperatures well below average this weekend and bringing precipitation. Freezing temperatures start to spread across the area Saturday morning, leading to freezing rain and sleet. Icing from freezing rain and sleet may impact road surfaces, making them slick and hazardous. Temperatures will likely remain below freezing through the weekend over most of the Winter Storm Warning area, so there could be residual ice impacts on road surfaces even after the precipitation stops. Avoid unnecessary travel and take extra travel precautions if you do have to venture out.
A Winter Storm Warning is in effect for the Hill Country and along and east I-35 corridor, north of San Antonio. Freezing rain is expected to develop across the Hill Country as early as Saturday morning, spreading southeast into Saturday night and Sunday morning. Travel will become dangerous in the warning area. Between 1/10 to 1/4 inch of ice is forecast in the warning area, with pockets of 1/4 to 1/2 inch possible over the Hill Country. There remains a potential for additional Winter Storm Warnings or Winter Weather Advisories to the south as the event approaches and confidence increases. Stay tuned for additional updates as the forecast evolves.
Here is the latest timeline where onset and end times are shown for the shaded areas. This does not mean accumulations will be continuous during these time windows. However, it can be assumed that some of the higher icing amounts will occur in the northern counties where the period of potential ice accumulation is longest.
An arctic airmass will arrive Friday night, bringing hazardous temperatures across all of South Central Texas this weekend. Sunday morning, wind chills could drop a few degrees below zero over a few areas with much of the area in the single digits and lower teens. Now is the time to think about preparing yourself and your home for colder weather.
As extreme cold sets in, it is vital to check on those most at risk, including newborns, the elderly, those with chronic illness, outdoor workers, and unhoused individuals. Ensure they are dressed in loose layers and have access to warm food and shelter.
Mild conditions are forecast tonight to Friday morning, with increasing clouds and temperatures mainly in the 50s. Morning fog is forecast mainly over the Coastal Plains and I-35 corridor. A few morning rain showers may trickle over portions of the area, mostly in the Austin area and Hill Country.
Temperatures are forecast to drop quickly Friday night through Saturday as Arctic air spread across South-Central Texas, including the potential for icy wintry weather this weekend. Check the forecast often. After liquid rain Friday, we expect to see shifts towards more freezing rain and sleet from north to south mainly Saturday morning through Sunday morning. Precipitation chances decrease past Sunday morning. Frigid cold temperatures may reach hazardous levels, especially overnight this weekend. Cold temperatures linger into next week, but a gradual warming trend is expected. Forecast details regarding the exact type and location of precipitation are subject to change, so stay informed with the latest forecasts.
