Cheyenne, Much of SE Wyoming Face Possible Strong Winter storm
What had been a Winter Storm Watch for Cheyenne and much of southeast Wyoming in connection with a cold front expected to hit the area tonight has now been upgraded to a Winter Storm Warning in effect late Monday night through Wednesday morning, according to the Cheyenne Office Of The National Weather Service.
As much as ten inches of snow and wind gusts of up to 50 mph are possible in some areas, according to forecasters.
The agency posted this statement on its website on Monday morning:
5AM/September 7th: OH SNOW!!! Mother Nature has a weird sense of humor to start early September! Winter Storm Warnings and Winter Weather Advisories are in effect for portions of Southeast Wyoming and the Nebraska Panhandle beginning overnight tonight through Wednesday morning. Rain will quickly change over to snow behind a strong cold front. Temperatures will DROP rapidly! The first onset of snow showers will melt-limiting the initial window of accumulation. BUT, in the areas that receive the moderate to heavy snowfall rates, the snow will accumulate rapidly. This is a very strong weather system that has the potential to cause major impacts for early September in localized areas. Strong gusty winds of 25-35mph are possible with this wintry weather, with gusts up to 45-50mph along I-80 between Rawlins and Laramie. Snowfall totals have been adjusted to account for initial snowmelt, and areas of higher uncertainty have been highlighted due to the mountain shadowing effect for Laramie, North Platte River Valley, and Pine Ridge area near Chadron. Please note that snowfall totals will NOT equal snow depth. Very cold temperatures Tuesday night into Wednesday morning are likely, especially in areas with the most snow. Check road conditions prior to venturing out. Dial 511 or visit wyoroad.info or 511.nebraska.gov for the latest road information.
