Wintry mix could close out 2020 in San Antonio area

SAN ANTONIO (KTSA News) – A cold front is expected to push through the area Wednesday afternoon, bringing some rain and a possible wintry mix Wednesday night into the last morning of 2020.

National Weather Service meteorologist Aaron Treadway says Monday with be cloudy and foggy with a 20 percent chance of rain, and the chance of precipitation increases to 30 percent Tuesday. The real show will be Wednesday afternoon when a strong cold front arrives and the chance of rain increases to 60 percent.

“Behind that, light precipitation continues, and with some cooler weather filtering in, maybe a wintry mix late Wednesday night into Thursday,” said Treadway.

Temperatures will fall into the 30s by Thursday morning.

“In this case, it’s mainly looking like it’s going to be a rain and snow mix, so it’s not looking like we’re going to have to contend with any ice problems,” said Treadway. “We’re not expecting anything to stick, but it is going to be cold enough in the upper atmosphere that we are going to get that snow mixed in with the rain late Wednesday into Thursday.”

He emphasized it’s a slight chance for a wintry mix, but we’ll keep checking the latest weather models for you.
