After a clipper system dropped a couple inches of fresh snow on the 13th, Arctic high pressure and blustery north winds pushed into the area. The coldest air and the lowest wind chills of the season spread across much of west central Minnesota. Wind chills fell to 35 to 50 degrees below zero late in the evening of the 13th and remained through the 14th and into the mid morning hours of the 15th. Wind chills were as low as 60 degrees below zero by the morning of the 15th. Many vehicles did not start because of the extreme cold and several schools had delayed starts.
The Arctic high pressure area settled in on the morning of the 15th bringing the coldest temperatures in many years. The combination of a fresh and deep snow pack, clear skies, and light winds allowed temperatures to fall to record or near record levels at several locations on the 15th. Browns Valley had a record low of -32 degrees and Wheaton and Artichoke Lake both had near record lows of -30 degrees on the morning of the 15th.

In fact, an all-time record low temperature was established at Cedar Rapids, Iowa on January 15 when the mercury dropped to 29 below.

This was round number two of two days of dry, fluffy, snow falling over roughtly the same area in south-central and southeast Wisconsin.  However, the axis of the greatest snow accumulations in round two was south of the Jan 9th winter weather event, and stretched from Janesville (Rock Co.) to La Grange (Walworth Co.) to Kenosha (Kenosha Co.).  Specific accumulatins included 8 inches in La Grange, 7.6 inches in Janesville, 7.2 inches just northwest of the the city of Kenosha, 6 inches in Burlington (Racine Co.), an estimated 5 to 6 inches in extreme southeast Green County, 5 inches in Racine (Racine Co.), 3.5 inches at a location 3 miles southeast of Palmyra (Jefferson Co.), and an estimated 3 to 4 inches in southeastern Lafayette County.  Since all of this snow fell over a 16-hour period, the impact on society was minimal.  Therefore, this event was classified as a Winter Weather event rather than a Winter Storm event.  Synoptically, a strong short-wave trough in the upper levels of the atmosphere moved east through the Midwest and concentrated snowfall over south-central and southeast Wisconsin, as well as over northern Illinois.

Farther to the north, snow continued to fall and changed to rain as late as around 6 a.m. EST in Sussex County. During the transition from snow to rain, some sleet also fell. The rain ended by Noon EST on the 9th. Most schools in northwest New Jersey had two hour delayed openings.
Specific snowfall included 7.5 inches in Wantage (Sussex County), 7.0 inches in Sussex (Sussex County), 6.1 inches in Jefferson (Morris County), 5.6 inches in Marcella and Rockaway (Morris County), 5.2 inches in Hardyston (Sussex County), 5.1 inches in Blairstown (Warren County), 5.0 inches in Lebanon and Tewksbury (Hunterdon County) and Knowlton (Warren County), 4.8 inches in Roxbury (Morris County), 4.3 inches in Denville (Morris County), 4.0 inches in Hamburg (Sussex County), 2.7 inches in Belvidere (Warren County), 2.4 inches in Hope (Warren County) and 1.5 inches in High Bridge (Hunterdon County), Bernards (Somerset County), and Greenwich (Warren County).
The wintry mix was caused by a strong surge of relatively warmer and more moist air above a surface warm front associated with an intense low pressure system that moved through the Great Lakes. A weaker low pressure  system formed on the warm frontal boundary early in the morning of the 9th near the Virginia and North Carolina border. This slowed the advance of milder air into the higher terrain locations.
