We started the day out with sunshine but clouds quickly moved in from the west as snow developed in western Iowa this morning. There is an area of low pressure in the upper levels of the atmosphere. Around noon today that low was located along the South Dakota/ Nebraska state line. It is forecast to track east tonight and Friday.
It was producing snow in South Dakota, Nebraska and western Iowa. Flurries are expected before midnight and after midnight light snow will develop. The light snow will continue through Friday and taper off Friday evening. Here is the forecast map for Friday evening.
There will only be about 0.10-0.20” of liquid in this system. The snow ratio is expected to be about 15:1 so that puts snow amounts about 1-2”. Some locations south of Highway 23 may see less than 1”. Areas along the Iowa/Minnesota state line might see 3” in a couple locations.
The cloudy sky will become partly cloudy Saturday and remain that way through the weekend.
A cold front is forecast to cross the state Monday morning with a mostly cloudy sky and a reinforcing push of cold air from the north to the south. Highs temperatures Monday and Tuesday will be in the teens. Here is forecast position of the front Monday morning.

1982: An intense storm system produced rare late December severe thunderstorms in southeastern Iowa resulting in straight-line wind damage from Lee through Scott counties. At Muscatine wind gusts to 90 mph blew down a 265 foot radio tower, while at Donnellson high winds destroyed an airplane hangar and damaged 7 planes. On the back side of the system in northwestern Iowa a major winter storm occurred on December 27-28 with freezing rain changing over to snow and accumulating to as high as 11.0 inches at Primghar, 11.5 inches at Le Mars, 12.5 inches at Sibley, 13.0 inches at Sheldon, and 14.0 inches at Hawarden. Winds behind the system gusted to 70 mph drifting the snow 6 to 10 feet deep and snapping power lines and poles.
1950: An arctic high pressure system settled across northeastern Iowa on December 27th resulting in very cold morning temperatures across the area, with many stations reporting their coldest December readings on record including -30 F at Osage, -31 F at Elkader, -34 F at Fayette, and -36 F at Decorah.
1904: A major winter storm struck much of Iowa from the afternoon of December 26th through the 27th and into the 28th. At first the precipitation fell as sleet and freezing rain, then it changed over to snow with strong winds producing blizzard conditions and blowing the snow into deep drifts making travel impossible. The heaviest snow fell across portions of southwestern, central, and northeastern Iowa with reported storm total accumulations of 10.0 inches at Mason City and Mount Ayr, 10.3 inches at Marshalltown, 11.0 inches at Cedar Rapids, 12.0 inches at Des Moines, and 15.0 inches at New Hampton. Many observers in northern Iowa noted the storm as the worst in more than 20 years. At Hanlontown in Worth County drifts more than 10 feet deep were reported with visibility less than 60 feet at times. The roads were blocked for several days after the storm across most of the state.
