More snow in store for US Rockies, High Plains following wintry weekend

Wintry scenes will be common across the Rocky Mountains and northern High Plains as more snow and slick travel are expected through Wednesday.

The Denver metro area received its first snow of the season at the beginning of the weekend, with the city’s international airport picking up half of an inch of snow.

People in Casper and Gillette, Wyoming; Rapid City, South Dakota; and Bismarck and Dickinson, North Dakota; also experienced a taste of winter this past weekend.

“The potential for slick travel and disruptions to daily routines is expected to continue as additional rounds of snow spread over the northern Plains and Rockies into Wednesday,” AccuWeather Senior Meteorologist Kristina Pydynowski said.

One storm system will charge into the Northwest into Wednesday, bringing accumulating snow to the Bitterroot Mountains of western Montana and Idaho, areas that were spared from snow at the start of the week.

Meanwhile, the storm that unleashed tornadoes over the central U.S. on Tuesday will strengthen into Wednesday, bringing a narrow swath of heavy snow on its northern and western flank.

Snow ramped up late Tuesday across eastern Colorado and western Nebraska. The snow will spread across the central and eastern Dakotas and northern Minnesota through Wednesday.

Precipitation may begin in the form of rain in some of these areas before colder air sweeps in and causes a changeover to snow.

As a result, roads that are initially wet can become slick and icy quickly, especially at night. People heading to work and school Wednesday morning will need to use caution.

With the anticipated snow, motorists are being advised that stretches of interstates 25, 90 and 94 can become slushy and slippery, according to Pydynowski.

“Treacherous travel may also unfold in the passes along I-70 and I-80 through the central Rockies,” she said.

Drier weather is expected to settle over the northern Plains on Thursday, but it will remain unseasonably cold with high temperatures only in the 30s.
