A "Bigfoot" of a Storm

48-hour snowfall accumulation ending this morning.
The winter storm that brought over a foot of snow and badly needed moisture to the Central Plains has an impressive footprint, with snow from Phoenix to Petosky over the last 48 hours. The storm is still producing, and several inches of snow will accumulate from the Michigan Upper Peninsula southeast into Ohio. The highest 24-hour totals reported by CoCoRaHS were from observers in central Kansas. However, the area of heaviest snow was rather broad and extended into southern Nebraska and western Missouri with amounts of 10 inches and more common. South of the main snow areas, freezing rain glazed streets, trees, and power lines from Arkansas northeast through central Indiana. Ice accumulations of one quarter to one half inch were reported by CoCoRaHS observers in Arkansas this morning.

CoCoRaHS observations for the morning of February 22 showing highest snow totals.

A weak low pressure system was centered over western Illinois this morning and will continue to move northeast.  An arc of precipitation extends from the northern Great Lakes into the central Appalachians. Winter weather advisories are in effect for a large portion of this area today.

Regional radar at 10:18 EST February 22.
