Winter is coming (again), Houston FacebookTwitterEmail Houston will be full of cold hearts this Valentine's Day. How cold? High temperatures in H-Town could be in the 20s by early next week if conditions are just right. There's still a lot of uncertainty about how chilly we'll get, or if we'll see any snow wintery precipitation. But here's where we stand, as of Tuesday's National Weather Service forecast: A cold front will make its way through Southeast Texas by Wednesday. It moved in slower than meteorologists expected, which is why Tuesday morning's fog was so intense. You can expect showers (and maybe some thunderstorms) to pop up around Houston starting Tuesday afternoon.
