The agency says the weather is "looking increasingly warm as the high-pressure system that has been baking the west coast slowly moves east into the Rockies.''

Outdoor events are likely going to be impacted by the rain and storms through the holiday weekend.

The main hazards will be 60 mph winds and localized quarter to golf ball size hail.

The agency also says that ''a brief landspout tornado can't be fully ruled out.''

Snowfall will result in slick roads and reduced visibility that could make travel difficult at times.

Low visibility and slick roadways are expected to make travel difficult at times, especially along Interstate 80 between Cheyenne and Laramie.

A few of these thunderstorms may become strong and contain strong gusty winds and some hail.

Another cold front is expected to pass through southeast Wyoming early next week, although forecasters aren't sure at this point exactly what to expect.

Please watch for slick spots in places along Interstate 80 this morning, especially around Arlington, Strouss Hill, the Summit, Vedauwoo, and Remount.

The Cheyenne Office of the National Weather Service has issued Winter Storm Warnings and Winter Weather Advisories for mountain ranges in southern Wyoming.

Travel over the I-80 summit between Laramie and Cheyenne could be a problem.

According to the Wyoming Department of Transportation Road and Travel report website, it didn't appear likely that the highway would re-open for several hours.
