If you're looking for last-minute Mother's Day gifts, you can't go wrong with a pair of galoshes and an umbrella this weekend.

The National Weather Service is predicting a major storm will whack Wyoming starting late Friday and continuing through Sunday, and it doesn't look like much fun.

"A large storm will slowly move through the region depositing as much as a foot of very wet snow in the western and central mountains during the period," according to the Riverton office of the Weather Service.

The storm will come in waves of rain and snow, which will start around 8,000 feet and head down to 7,000 by Friday morning.

By Saturday morning, the precipitation will affect areas in the 6,000-foot elevations and then get everywhere by Saturday night and through Sunday.

"The heaviest precipitation with this system is expected to occur on Saturday and Sunday," according to the National Weather Service.

"On early Sunday morning, snowfall rates of an inch per hour are possible, especially in eastern Fremont County including Lander, around Casper, and Buffalo. The precipitation will hang around through the day before ending from northwest to southeast late Sunday night," according to the weather service.

Travel will be messy.

"Expect winter driving conditions with roads becoming extremely slick and snow packed at pass level. Slushy roads are possible along Interstate 25 and around Casper on Sunday but most roads will remain wet. Expect areas of fog and a few icy roads early Monday morning," according to the weather service.

Southeastern Wyoming faces the same fate, with rain and snow showers through Friday and increasing on Saturday and Sunday, according to the Cheyenne office of the National Weather Service.
