If you woke up this morning like me and checked the weather app on your phones you may have seen flurries forecasted for the area. But according to the latest situation report from the National Weather Service, San Antonians will be better off carrying an umbrella and rain boots this Sunday, rather than their winter coats. (Who am I kidding, you’ll probably need those as well, seeing as how cold it is.)
While there remains a low chance for a patchy, light wintry mix this Sunday, the NWS says that possibility is only forecasted for parts of the Texas, Hill Country. So, all clear on that front, y’all.
However, what locals can expect this Sunday, is more precipitation. A cold and cloudy Sunday is underway for San Antonio as temperatures continue to struggle out of the 30s in many locations. A 50 percent chance of showers is forecasted for the area today, with much of that expected to land mainly after noon, the weather agency says.

Sunday night, possible thunderstorms are expected to produce heavy rainfall. According to the NWS, there’s a level 1 of 4 risk for excessive rainfall that could lead to isolated pockets of flooding in certain areas, while wind gust speeds could reach as high as 25 mph.
Come the morning of Monday, January 22, isolated thunderstorms are again forecasted for the area. Chances for precipitation are currently set at 80 percent, with rainfall amounts set between a quarter and half of an inch possible, the weather service adds. Additional scattered rainstorms are said to continue through Wednesday, January 24. So, be sure to give yourself some extra time this week before leaving for work as morning commutes are expected to be jammed-packed to start.
