March 13th, 7pm - A snowy and windy weekend is ahead for southeast Wyoming and western Nebraska. The best chances for snow will be west of the Laramie Range on Friday and Saturday, but cannot rule out the possibility of a trace to half an inch of snow east of the Laramie Range. Winds will be strong on Friday with High Wind Watches and Warnings in effect. There will be a brief lull on Saturday as winds decrease, but they are expected to ramp right back up Sunday into the start of the week.
March 13th, 6pm - Another round of strong winds is in store for Friday. As a result, several of the High Wind Watches have been upgraded to High Wind Warnings. High winds are expected to start as early as 8am on Friday and continue through midnight. Here’s a breakdown on timing: Arlington, I-80 Summit, and Foothills: 8am Friday - Midnight Friday Niobrara and North Sioux Counties: 10am Friday - 9pm Friday Central Laramie County east through Cheyenne County: Noon Friday - 9pm Friday Watches: 10am Friday - 9pm Friday
A winter weather advisory has been issued across western portions of our CWA including the Sierra-Madre, Snowy, and Ferris Ranges, as well as Rawlins and Arlington areas. Overall snowfall accumulations will likely be light, only around several inches at best, but the combination of light to moderate snowfall alongside gusty winds promoting periods of limited very low visibilities will bring problematic travel to the region.
