Apart from dense morning fog in spots, there will be very few weather-related problems if you or your loved ones plan on traveling across the state of Texas through New Year’s Eve. And if you’re hoping for colder weather, a strong cold front is set to arrive the first weekend of 2022.

Here’s what you need to know:

WEDNESDAY & THURSDAY

  • There won’t be much change to our weather on Wednesday: unseasonably warm with afternoon sun
  • Thursday will still be a warm day, but humidity will be down slightly - especially in the morning

NEW YEAR’S EVE & NEW YEAR’S DAY

  • It’ll still be very warm with highs near 80° both Friday and Saturday
  • As we ring in 2022 Friday night, temperatures will be in the mid- to upper 60s and it will be muggy

STRONG COLD FRONT SOON

  • A strong cold front will arrive late in the day Saturday
  • This front will result in a significant temperature swing - from the low 80s on New Year’s Day to the 50s on January 2nd

FIRST FREEZE POTENTIAL

  • Believe it or not, it’s not hit freezing yet at San Antonio International Airport
  • However, behind this weekend’s cold front, San Antonio could register its first light freeze Sunday night/early Monday morning
