Arctic Blast On The Way!

By Brian Alonzo

On Thursday morning the weather is going to change for all of South Central Texas. Arctic air from Canada will be moving southward towards our area. On Thursday a powerful cold front will be bring a small chance of precipitation. Due to the forecasted profile of the atmosphere we could see some sleet with this front. That is a very small chance and no accumulation is expected. One thing that will accompany this cold front will be high winds. Winds will be out of the north 15-25 mph with higher gusts around 30-35mph. It will make the air temperature feel colder. Wind chills could be in the 20’s and teens.

On Friday, the winds will calm down to 10-15 mph and by night fall temps will fall to the 20’s. By early Saturday morning with light winds, clear skies, temps will be in the upper teens in San Antonio and lower teens across much of the Hill Country.  A Hard Freeze can be expected on Thursday through Saturday for most of the area. Wind chills could even touch single digits in the Hill Country.

So what can you do to prepare now?

If you have lots of plants and if they are sensitive to the cold, start covering them now.  To prevent outdoor pipes from bursting, they should be wrapped, drained or be allowed to drip slowly. If you have an in ground sprinkler systems water should be drained. For indoor pipes, open cabinet doors to let warm air circulate. Also, allow a slow drip.

If you’re going to work or school: Allow extra time to warm up the car. Clean the frost(if any is on your car) off all windows.

Clothing: Dress in layers wearing lightweight clothing, which will keep you warmer than a single heavy coat. Mittens and hats that can cover your ears will help out.

Most important don’t forget about your pets. Bring them inside.
