Officials say a mixture of rain and snow will develop over area Friday evening before switching over to all snow past midnight Friday into the early morning hours on Saturday.
The heaviest accumulations are expected to occur Saturday morning into Saturday afternoon before it tapers off Saturday evening. Total snowfall across southwest and western Iowa may range from 4- to 7-inches. In addition, northeast winds at 20- to 30-miles per hours with higher gusts possible, are expected to cause significant visibility restrictions and drifting of snow on Saturday and Saturday night.

OMAHA, Neb. (AP) – A powerful winter storm system that could dump a dozen inches of snow in blizzard conditions has been forecast for Nebraska and portions of adjacent states. A blizzard warning has been issued for three southwest Nebraska counties and nearby portions of Kansas and Colorado. The National Weather Service says the warnings take effect at 11 p.m. MST Thursday. A blizzard watch extends to the northeast.
Winter storm warnings and watches have been issued to take effect later Thursday or on Friday for the rest of Nebraska and much of southeast Wyoming, northeast Colorado, northwest Kansas and western Iowa. The Weather Service says the storm is expected to move into Nebraska late Thursday night and last into Saturday. Rain is expected to precede the snowfall in many areas.
Here in western Iowa, snowfall amounts through 6-p.m. Saturday, are expected to range anywhere from 2-inches in Page County, to more than 7-inches in Pottawattamie County. Cass County looks to receive just under 5-inches of snow, according to the latest estimates.
The first three days of this week saw record breaking temperatures set in Atlantic, but there’s little liklihood today will come close to the record high for this date. Wednesday’s high in Atlantic was 60, which broke the old record of 58, set back in 1987. Today’s record high was 66, in 1992, but the forecast only calls for a high of around 56-degrees.
A major change in the weather is set to take place late Friday night into Saturday night, as a snowstorm sets its sights on Nebraska and Western Iowa. Right now, it appears snowfall amounts will range from 4-to 7-inches, but that could change, depending on the track of the storm, and how late the rain we get on Friday, changes to snow.
A Winter Storm Watch will be in effect for most of the listening area, from late Friday night into Saturday night. Travel conditions are expected to deteriorate Friday night, with reduced visibilities due to blowing heavy snow, and slushy road conditions.
Here’s the forecast for Atlantic, and the KJAN listening area, plus the weather stats for Atlantic.
