St. Louis City officials are mobilizing to protect the city's homeless population as an arctic weather front is forecast to plunge the region into sub-zero temperatures late this weekend.

The National Weather Service says a winter storm could dump nearly a foot of snow on the St. Louis area by Sunday evening. The overnight low temperature on Sunday is forecast to reach -8 degrees with daytime highs on Monday peaking near -2 degrees.
