Snow, icy road conditions prompt winter weather advisory Jan. 14 for the Milwaukee area

A steep drop in temperatures overnight and snow has caused icy road conditions for much of southeastern Wisconsin for the morning commute Wednesday, Jan. 14.

The National Weather Service issued a winter weather advisory Jan. 14 across most of southern and southeast Wisconsin, as far north as Sheboygan County in the east and Sauk and Adams counties in the west. The advisory remains in effect until 10 a.m.

Cameron Miller, a meteorologist with the National Weather Service in Milwaukee/Sullivan, said there have been multiple reports of accidents around the area.

“It was kind of a perfect storm, honestly. The combination of the snow that we had in the roads, warm pavement temperature and then air temperatures quickly falling from the 30s into the low 20s, basically caused conditions that were conducive to icing on the road,” he said.

The Wisconsin Department of Transportation’s traveler information website, 511wi.gov, showed several reports of accidents in Milwaukee and surrounding areas as of 8 a.m. Jan. 14.

The snow should let up around mid-morning, Miller said. Snow accumulation in the Milwaukee area Wednesday, Jan. 14 is not expected to be more than a few tenths of an inch – just a dusting, Miller said.

Another round of snow is forecast to move in the night of Thursday, Jan. 15, and continue through Saturday, Jan. 17.

“It’s going to be a long-duration snow event. So it’s going to be basically white snow throughout that entire time, and really only going to be a couple of inches of accumulation,” Miller said.

Miller said the precipitation later in the week will likely not bring any more winter weather advisories. Icing should be less of a problem, as temperatures are expected to stay below freezing in the coming days.
