As is typical for a winter in San Antonio, it’s been up and down the temperature rollercoaster for those of us around South Central Texas. Another strong cold front will move through San Antonio Wednesday evening (1/19). Temperatures will come crashing down from near 80° all the way into the 30s. After it gets cold, an upper-level disturbance will bring a light wintry mix of freezing rain, sleet, and a few snowflakes on Thursday (1/20). As a result, a Winter Weather Advisory has been issued for the San Antonio and the KSAT viewing area.
