The Northern Hemisphere is covered with snow - on the Globe-Democrat's globe, that is. The view is looking west on Delmar boulevard. St. Louisans can expect more of the same - snow flurries, that is - with a 2-to-4-inch accumulation before it ends sometime early Sunday morning, the National Weather Service said Friday. And the weather will continue to be on the chilly side with a high temperature in the 20s Saturday and Sunday and the low 10 to 15 degrees Saturday and Sunday nights.
