BUNDLE UP 🧤🧣: FOX Weather Meteorologist Haley Meier gives an update on a cold front settling over the U.S. this week, which will keep temperatures below freezing and even in single-digits for some places. Frostbite and hypothermia can set in quickly with conditions like these, so make sure to bundle up in layers and limit outdoor exposure. #staywarm #freezingtemps #bundleup
