Frigid Temperatures and Arctic Blast Expected to Hit San Antonio Next Week
Oh San Antonio, we’ve had quite the rollercoaster start to the year! While we kicked off January with freezing temperatures and a blanket of gloom, it seemed like warmer weather was on its way this week. But brace yourselves—the cold from the Arctic is making a return next week!
What to Expect This Weekend
So, what’s in store? Well, mark your calendars for Saturday night when a modified arctic air mass will arrive in South Texas. We are looking at some very chilly mornings, especially come Monday, January 20, and Tuesday, January 21.
Expect low temperatures to drop into the mid-20s, and those daytime highs? Only the low-40s on Monday and upper-30s on Tuesday. Yikes! That’s about a 15-degree drop below the typical January average low of 41 degrees.
Temperature Drops Across Texas
This cold blast will affect not just San Antonio, but below-average temperatures will grip the entire state. Central and North Texas may see their first freeze of the week as soon as Sunday morning, with highs staying below 32 degrees in some areas.
Oh, and let’s not forget the wind chill! On Tuesday, it could feel as cold as 17 degrees outside—definitely not ideal for those morning joggers or dog walkers!
Precautions are Key
With these temperatures, it’s crucial for residents to take precautions. Here’s what you need to do:
- Protect your pipes to prevent them from freezing.
- Shield your plants so they don’t suffer in the cold.
- Bring pets indoors to keep them safe and warm.
- If you plan to be outdoors, layer your clothing.
Where to Go for Warmth
If you need a break from the chill, warming centers and libraries will open their doors during the day. Community centers and senior centers will also welcome folks looking to escape the cold. Overnight shelters will be ready for anyone in need of a safe place to stay as temperatures dip.
Stay Alert for Possible Snow
A Quick Look at History
Historically speaking, January in San Antonio has seen even colder temperatures. The record low was zero degrees back on January 31, 1949! For perspective, lows of 17 degrees were recorded on January 20, 1943, and again on January 21 in 1985 and 1924.
Conclusion: Safety Comes First
Stay warm, San Antonio! Keep those sweaters close and enjoy this winter wonderland while it lasts.
