Winter Storm Warnings and Winter Weather Advisories are in effect early today through Sunday noon as an Arctic front brings primarily freezing rain and some sleet to the area. Hazardous conditions begin at 3 AM Saturday north of the I-10/US 90 corridor and expand south by 3 PM, causing dangerous icing on roads that will likely persist through the weekend due to sustained freezing temperatures. Please avoid unnecessary travel and exercise extreme caution if you must venture out. Avoid unnecessary travel and take extra travel precautions if you do have to venture out.
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.
A Winter Storm Warning is in effect for a good portion of South Central Texas with a Winter Weather Advisory in effect for the southern counties of the Rio Grande. Freezing rain is expected to develop across the Hill Country as early as 3 AM Saturday, spreading southeast into Saturday afternoon and continuing through 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. 1/10 inch of ice or less across the Winter Weather Advisory area.
Here's the latest forecast for when we expect to see accumulating ice. These time windows do not mean icing will be continuous, but longer time windows over northern counties could lead to more ice accumulation.
Freezing Rain is the Worst. Freezing rain is more dangerous than snow, as ice can form on pavement. Watch out for falling branches and powerlines. Use extreme caution if there is, or recently was, freezing rain.
Protect people, pets, pipes and plants from cold weather. People: 1) Minimize time outdoors. 2) Prepare for power outages. 3) Check on the elderly and other vulnerable people to make sure they're ok. Pets: 1) Keep your pets warm, dry and indoors as much as possible. 2) Ensure their food and water doesn't freeze. 3) Limit outside time and keep them bundled up. Pipes: 1) Insulate pipes if possible. 2) Open up sink cabinets to expose pipes to heated air. 3) Disconnect hoses & turn off water to sprinklers. Plants: 1) Know their temperature thresholds. 2) If possible, cover them before the cold weather sets in to help retain some heat.
