…WIND CHILL ADVISORY IN EFFECT FROM 6 AM TO NOON CST MONDAY..

Roads around western Iowa are reported to be completely covered with snow early this (Sunday) morning. The Iowa Dept. of Transportation’s website at 511ia.org, shows all roads south of Highway 30 and east of the Interstate 80/680 split, down to the Missouri border, are covered with snow. Blowing snow was also a factor in the morning commute to church or work. Towing services are prohibited today in Cass and Adair Counties…meaning if your vehicle goes into the ditch or median, towing companies are not allowed to pull you out until the weather improves.

Some roads in far western Pottawattamie County were partially covered with snow, including I-29 from the I-80 split, south, and portions of Highways 6 and 92. North of I-80 in far western and northwest Iowa, where there was less snow, the roads are in mostly normal driving condition.

Here in Atlantic, we had received 2.5-inches of snow, as of 6-a.m., and roads were 100-percent snow covered, with blowing and some drifting of snow.

DES MOINES, Iowa (AP) — Iowans across much of the state are preparing for a wintery blast that’s predicted to bring up to 8 inches of snow to some areas. The National Weather Service says a winter system is expected to bring snow and ice Saturday night, starting in Iowa’s southwest corner and moving up to its northeast corner. South-central areas are expected to see less accumulation — between 3 to 5 inches in the Des Moines area — while more southern regions could see up to 8 inches of snow.

Meteorologists say light snow is expected to begin around mid-afternoon Saturday in central Iowa and gradually get heavier into the night until about 3 a.m. Sunday. Frigid conditions follow, with temperatures expected to drop to and remain in the single digits on Monday.
