The Wyoming Department of Transportation put out a video on Monday warning that winter weather was coming early, and that I-80, I-90 and I-25 could be in for trouble through Wednesday morning.
"After enjoying a prolonged period of unseasonably warm fall weather in the state of Wyoming, we are going to quickly turn to a much colder system that'll bring fall and winter road impacts alike over the next 48 hours or so," said the video's narration. "There are challenges galore with this system as multiple impacts can be expected through the state starting early [Tuesday], most of them occurring through the afternoon and evening with residual road impacts lasting through at least Wednesday morning."
WYDOT released the below map to help drivers visualize the impacts. The usual suspect and the scene of 2022's "Winter from Hell" in Wyoming, the stretch of I-80 between Laramie and Rawlins, looks like a bad patch for the next day or two.
That stretch struggles with high elevation and sweeping winds that can blow feet of snow onto the interstate just hours after it's reopened by road crews.
"When all is said and done roadways should have some slush on them with a little snow accumulations possible; also widespread slick roads and black ice Tuesday night into Wednesday morning," the video continued. "Complicating matters is the fact that temperatures on Tuesday will be steady then fall through the afternoon, and even as our storm system lifts into the high plains Wednesday, we're going to stay cold on the back side of that system which will result in slow road improvement."

If heavier snow develops, I-80 near the Utah line through Evanston Rock Springs extending to Rawlins could see heavier impacts, as well as northern I-25 and parts of I-90 near the Big Horn Basin.
WYDOT also warned of a "stiff northerly wind at around 15 to 35 mph that should should cause areas of blowing snow and reduced visibility," as well as "slush, slick roads and black ice" from Tuesday night through Wednesday morning.
