Comal ISD will resume classes Wednesday as the weather forecast calls for clear skies.
The district said parents and guardians should continue to monitor social media and local news for any possible updates, spokesperson Salwa Lanford said.
All New Braunfels ISD schools and offices will be open and operating on regular schedules as well, the district said on Facebook. All extracurricular activities will proceed as planned.
A cold advisory remains in effect through Wednesday morning.
The weather will be mostly clear and very cold tonight with lows in the teens and lows 20s across the region, the U.S. National Weather Service Austin-San Antonio said. Wind chills will range from the mid to upper single digits in the Hill Country to the teens elsewhere.
