6:30 AM October 12th – Here it is! First winter storm of the season will be developing today across the area as portions of central Wyoming already saw snowfall yesterday. As of early Tuesday morning, Rawlins and Douglas have reported snowfall which will continue throughout the day and tonight. Lower elevations west of I-25 could see rain mixed with snow before transitioning to all snow tonight. Widespread, heavy snowfall can be expected by later this afternoon into tonight with 4 to 10 inches of snowfall in the lower elevations of Carbon, Albany, and Converse Counties in Wyoming. Therefore, a Winter Storm Warning is in effect for the area through Wednesday morning. Most of the Nebraska Panhandle will be too warm to receive accumulating snowfall, however strong to severe thunderstorms with heavy rainfall are expected Tuesday afternoon and evening. Strong winds are likely to develop tonight and Wednesday morning across the South Laramie Range through the southern Nebraska Panhandle. Therefore, a High Wind Warning is in effect from 12 AM Wednesday through 6 PM Wednesday for 60 MPH wind gusts. For areas receiving measurable snowfall, these winds could result in whiteout conditions and hazardous travel, especially along Interstate 80 near Arlington/Elk Mountain and at the Summit between Cheyenne and Laramie. Be sure to have your winter safety car kit ready if you're traveling through the highlighted area above!

Drivers are encouraged to call 511 or go to wyoroad.info for the latest road conditions and closure information.
