The National Weather Service says “A significant winter storm” will affect the region today and into tonight. A Winter Storm Warning continues until 9-p.m. today (Sunday). Heavy snow will continue to fall across much of Iowa and winds will increase, causing blowing snow and drifting snow that will make travel even more hazardous. The snow will finally end with diminishing winds late this evening. As of 7-a.m. in Atlantic, we had received 5.8-inches of snow, which melted into just over six-tenths of an inch of liquid precipitation. Massena had 6-inches of snow over the same 24-hour period ending at 7-am.
Other snowfall reports as of include: 6.9 inches in Oakland (8:30-a.m) 7 inches in Audubon, Carroll and Guthrie Center; 5.4 inches in Adair; 9.8 inches in Waukee and 7.9 inches in Ames and 7.3 inches in Des Moines.
As of 8-a.m., roads were 100-percent snow and ice covered in the KJAN listening area, and many churches had cancelled services for today. Towing services are prohibited in Cass, Adair, Pottawattamie, Mills and Fremont Counties.
Additional snowfalls will be possible in the coming days, especially from Tuesday into Wednesday when some accumulations are expected. Temperatures will be quite a bit colder for most of next week with the fresh deep snow cover in place. The coldest temperatures will come tonight into Monday morning and again from Wednesday night into Thursday morning.
