Winter Storm Harper is already pummeling parts of the West with heavy snow and will spread its mess of snow, ice and wind into the Plains, Midwest and Northeast into this weekend.
Harper's heaviest snow, so far, is in the Sierra Nevada of California. Early Thursday morning, Lone Pine, California, reported 5 inches of snow had fallen in just 2 hours.
That storm will tap into cold air once it moves through the central and eastern states Friday through the weekend, delivering a widespread swath of significant snow.
