The winter storm has brought significant snow, dangerous ice storms and freezing rain across North America
A bitterly cold Arctic airmass, which has gathered across Canada in the past week, has spread southwards into the US over the weekend. Having already allowed temperatures to fall as low as -40C in northern Canada, this cold airmass combined with moisture-laden air from the Gulf of Mexico to become a major winter storm named Blair, bringing disruptive winter weather across a wide area of the US.
Over the past 24 hours, Blair has brought significant snow accumulations as well as dangerous ice storms and freezing rain across a wide area, from the central Great Plains in the west, across the Mississippi and Ohio Valley, and on to the east coast.
