MINNEAPOLIS (AP) — Freezing drizzle and rain made roads slick Sunday as a winter weather system moved across portions of the Upper Midwest, and the precipitation was expected to begin changing over into snow that could continue into Monday.
The National Weather Service issued warnings about freezing drizzle and rain for parts of Illinois, Iowa and Minnesota and Wisconsin on Sunday, and a fog advisory was out in south-central Wisconsin.
The advisories could be expanded later Sunday, the weather service said. The precipitation was coming from a low pressure system expected to track east across Nebraska and Iowa and deepen as it moved northeast across Wisconsin, it said.
Snow was expected Sunday in Nebraska and the Dakotas with a few inches falling in parts before midnight, the weather service said.
In other states, the changeover from rain to snow was expected to start Sunday evening and move from west to east, continuing into Monday morning. One to two inches of snow were possible by Monday in the Twin Cities area of Minnesota and parts of central Wisconsin, the weather service said.
In southeastern Minnesota, Rochester police responded to more than 70 crashes on slick roadways Sunday morning, Lt. Mike Sadauskis said.
"People probably need to take their time a little bit better, give themselves a little bit more space," he said.
Ice also was expected to develop roads and sidewalks in the Twin Cities and elsewhere in the region, with up to a tenth of an inch of ice was possible, the weather service said. It urged drivers to be cautious and anticipate road conditions to deteriorate throughout the evening.
Glazing was reported Sunday across portions of northeastern Iowa and southwestern and central Wisconsin, the weather service said. In the Milwaukee area, freezing fog could reduce visibility to less than a quarter of a mile, it said.
North Dakota got freezing rain and snow Saturday into Sunday that left roads in the southern half of the state coated with ice.
Strong winds were expected in Arkansas, Oklahoma, Texas and Nebraska, where light snow began in the western part of the state Sunday afternoon.
The worst of Nebraska's storm was expected Sunday evening, with 2 or 3 inches of snow falling expected in some parts. The weather service said the main threat from the storm was likely to be blowing snow that could limit visibility Sunday evening.
