Immediately behind our large rush of arctic air and dangerous cold, a widespread winter storm will slide across the Central and Eastern United States. This will bring a very large swath of heavy snow, sleet, freezing rain, and bitter cold across much of the country. With our arctic high pressure in place in Northern Illinois, the bulk of the precipitation will remain off to our South. But trends have been subtly pulling the Northern edge of this snow our direction over the last few days.
Winter storm alerts stretch from Western New Mexico all the way up into the Northeastern part of the Country, nearly 2000 miles from one end to the other! Winter storm watches are being converted over to warnings as confidence increases on the potential for accumulating or heavy snowfall. A few ice storm warnings have been issues for parts of the Southeast, including Northern Mississippi for the potential for an inch of ice accretion.
While nearly all of the snow will end up South, we will see the potential for at least a few snow showers creep toward the Stateline Saturday afternoon into Sunday morning. Any snow showers we see this far North will be lighter in nature, and some in Northwestern Illinois or Southern Wisconsin may remain completely dry. But given the bitterly cold air in place, any snow that does come down will stick to the surfaces and cause slick conditions. Road treatments will not be as effective with temperatures remaining in the single digits or lower through Sunday morning.
