Thursday: Mostly sunny. High: low teens.

Friday: Mostly sunny. High: upper teens.

Clouds and flurries will linger tonight with little to no additional accumulation. Snow totals are ranging from a trace to 3” across eastern Iowa. Most locations are close to 1”. Click here for some reports as of 6:00 this morning.

Here is the snow depth across the Midwest as of this morning.

On Saturday, high pressure will move across the middle of the country and clear out the clouds as the upper level low moves east. Sunday will be a little warmer but it will also be breezy so there will be a wind chill to negate the warmer temperatures.

A cold front is forecast to cross the state Monday with clouds and colder temperatures Tuesday. Another other cold front is forecast to track south across Iowa Wednesday with clouds and again colder temperatures Thursday and Friday. The fronts are expected to come through dry each time.

If you have plans to be out New Year’s Eve it will be cold.

December 28

From NWS
: A winter storm produced heavy snow across north central and northeastern Iowa on December 27-28 with storm total accumulations of 11.0 inches at New Hampton, 11.5 inches at Decorah, 12.0 inches at Elkader, 12.5 inches at Osage, 13.0 inches at Waukon, and 14.0 inches at Northwood.

1984: Unseasonably warm weather brought the temperature all the way up to 70 F at Ankeny, Knoxville, and Oskaloosa and a high temperature of 69 F at Des Moines tied the all-time December record at that location. Even in northeastern Iowa the temperature climbed all the way to 65 F at Guttenberg, making it the warmest December reading on record at that location.

1924: Iowa experienced its coldest December morning on record with a statewide average low temperature of -25 F. Individual station low temperatures included -32 F at Corning and Thurman and -30 F at Pella and Sigourney.

This Day in National/World Weather History …
 28 December 1879 → All 74 lives were lost when a passenger train plunged from the Tay Bridge (Dundee, Scotland) into the Tay Estuary as the middle section of the bridge collapsed. Although the bridge was poorly constructed and had already been weakened in earlier gales (including the pre-existing winds at the time of the tragedy), the ultimate failure is believed to have been caused by two or three waterspouts which were sighted close to the bridge immediately before the accident.
 28 December 1999 → It took only two hours for winds to destroy two centuries of history. The usually peaceful gardens at Versailles, France became a weather-beaten battlefield during violent storms that killed more than 100 people in western Europe and reduced some cultural treasures to ruins. Many 200 year old trees were uprooted.
 28 December 2003 → A severe snow storm hit northern California and southern Oregon. As much as 2 feet of snow fell along Interstate 5 closing a 150-mile stretch of the highway, stranding hundreds of travelers. Winds from the storm caused power outages to more than 200,000 customers. One man died of a heart attack after helping other drivers.
