SE Wyoming Bracing For Arctic Front, -25 Wind Chills, Blowing Snow

The Cheyenne Office of the National Weather Service says an "impactful winter storm" this week is likely to blast southeast southeast Wyoming with double-digit low temperatures, wind chills below -25, and blowing snow.

That's according to a post on the agency's website:

An active week ahead as confidence grows for an impactful winter storm mid-week. Before the snow arrives, a prolonged high wind event begins for southeast Wyoming this afternoon and continues over the next few days before finally winding down Tuesday afternoon. Winds during this time could gust over 80 MPH for the wind prones, and over 70 MPH for the plains/lower elevations of southeast Wyoming. Biggest impact will be to transportation, where strong crosswinds will pose a blowover risk for lightweight and high profile vehicles. Western Nebraska could also see strong winds during this time. A prolonged mountain snow event also begins early Monday morning and continues through early Thursday morning. During this time, the Snowy and Sierra Madre Ranges will pick up multiple feet of snow. Strong winds are also likely which could lead to whiteout conditions at times. Outdoor recreation could become life threatening to those caught unprepared for severe winter conditions. Snow begins for the plains/lower elevations Tuesday evening as the arctic front passes through, and continues through Wednesday evening. Moderate to heavy is likely, as well as patchy blowing snow. Widespread accumulations of 5+ inches are possible. Lastly, this arctic front will bring extremely cold temperatures, especially Wednesday and Thursday. High temperatures those days will be in the single digits and teens. Overnight lows will be below zero with wind chills Wednesday night into Thursday morning likely falling below -25°F. Be sure to stay tuned for more updates to this storm.

Cheyenne is expecting possibly heavy snow, low temps of around -14 and much colder wind chills for Tuesday and Wednesday. Laramie is expecting similar conditions, with lows of around -12 and blowing snow.
