San Antonio – If you’re a fan of warm December days, then there’s no doubt that you’ve loved the weather this weekend! High temperatures across South Texas were in the 70s and 80s both Saturday and Sunday.

However, don’t get used to this weather. Another round of big weather changes is just around the corner!


Foggy start, then warm and muggy today

Dense fog has settled in around South Texas, prompting a Dense Fog Advisory until 10am. The advisory includes Bexar County, where visibility has dropped to near a quarter of a mile. Drizzle and mist will also accompany the fog.

The fog will lift and skies will start to clear by this afternoon. Some spots will clear out earlier than others, and that could create a big spread in high temperatures. Those that see sun earlier in the afternoon will have high temperatures in the low to mid-80s, while those that stay cloudy longer will see temperatures in the 70s.


The Cold Front Arrives

In typical Texas fashion, we’ll quickly make the change from wearing short sleeves to needing our jackets! An arctic cold front will arrive in San Antonio Monday night, dropping temperatures nearly thirty degrees from Monday afternoon to Tuesday afternoon.

Wind chill values will quickly drop into the 30s tomorrow morning.

Along with the big drop in temperatures, this cold front will also bring us a chance of some much-needed rain.

Light showers will be possible overnight, as the front slides through.

Rain chances increase to around 60% Tuesday morning after the cold front moves through.

A chance of showers will linger through Tuesday midday.

By Tuesday evening, rain chances will come to an end and skies will begin to clear.

There will be no severe weather associated with this cold front. In fact, all rain will be fairly light.

Unfortunately, that means that rainfall totals from Monday night through Tuesday evening won’t be impressive at all. Most South Texas locations should expect less than a quarter of an inch of rain.

As skies clear Tuesday night, temperatures will fall into the 30s across South Texas through Wednesday morning. Brrr!

COLD FRONT TUESDAY
