A winter storm warning remained in effect for parts of southeast Wyoming on Friday morning, with up to 10 inches of snow possible at higher elevations.

Travel impacts could be probable west from Cheyenne and west of the Laramie Range for the higher terrain. Please use caution during this time frame if planning on traveling.

Meanwhile, a Winter Storm Watch has been posted for some areas of southeast Wyoming, including the summit on I-80 between Cheyenne and Laramie.

The Cheyenne Office of the National Weather Service says hail and strong winds are possible this afternoon [May 17] in southeast Wyoming and the Nebraska Panhandle.

A cooling trend is expected later in the week with rain and even some snow possible.

The main hazards of the storms will be small hail of up to an inch in diameter and winds that could reach 60 miles per hour.

The average last freeze date for Cheyenne over the last 30 years has been May 15, although in 2007 it was a bit later, being recorded on June 8.

Some showers and thunderstorms will develop late in the afternoon into Wednesday night.

There's only been one EF4 tornado in Wyoming history and it happened in the summer of 1987. It was a rare monster high-altitude tornado that carved a path of damage from the Teton Wilderness through Yellowstone National Park.

The warning includes Arlington, Laramie, Cheyenne, Wheatland, Lusk, Torrington, Harrison, Chadron and Alliance as well as the I-80 Summit between Laramie and Cheyenne.
