This is a little conservative DISD. My kids played outside in the paper think layer of snow almost all morning. It's not closure weather out there.

It's not about our weather dropping below freezing, it's about the infrastructure we have (physical, institutional, social) to deal with these events. Prolonged periods below freezing like this are very rare here. Prolonged periods in the teens even more so. It's a type of cold our physical infrastructure struggles with even with the mitigation strategies in place.  It's something we institutionally struggle with as well (DISD being an institution is that has to struggle with probable reduced staffing, coordinating the logistics of keeping the schools warm, the difficulties of teaching when something"exciting" is happening, and struggling to keep kids safe in adverse conditions that most staff has little experience with). Also, most people lack the resources at home to deal with the cold. Many people lack proper coats for weather like this because it's a rare occurrence and everything tends to shut down - especially for kids who grow like weeds anyway and might get one use out of an expensive set of winter gear if you're (un)lucky. On top of that, not every household would be able to guarantee their kids safety waiting for buses outside or walking in weather where frostbite can happen when the windchill lowers the temperature to near 0° values.  This isn't normal for us. Stop being upset that things aren't working normally in abnormal conditions
