A strong cold front is expected to move through Wyoming over the weekend, bringing with it the possibility of snow and very strong wind. The National Weather Service has issued a High Wind Watch in effect from Saturday night through Sunday evening, for much of southeastern Wyoming and the Nebraska Panhandle.

"A High Wind Watch means there is the potential for a hazardous high wind event. Sustained winds of at least 40 mph...or gusts of 58 mph or stronger may occur. Continue to monitor the latest forecasts."

The Weather Service says the wind could create significant travel and road impacts from Sidney to Elk Mountain on I-80 and from the Wyoming/Colorado state line to Chugwater on I-25.

Heavey, blowing snow is expected for Snowy, Sierra Madre Ranges and foothills Saturday through Monday, as well.
