Today is the last day to prepare across the Northeast as the snow will begin to move in from the southwest tonight.

However, 8-12 inches is still expected at these major hubs despite the chance for ice. A wide swath of 12-18 inches of snow will be possible for areas that see all snow and no mix, and this includes Boston. Get your hour-by-hour forecast and the latest snow and ice totals here.

Winter Storm Fern is dumping heavy snow across Texas, Oklahoma and Arkansas, transforming communities that rarely see winter weather like this.
