SYNOPSIS: A Pacific storm will impact the area today, with snow expected over the western mountains. Warm southwest flow ahead of the storm will allow for a rain/snow mix in the valleys for much of the day before the cold front sweeps through. Precipitation east of the Divide will be showery and primarily rain this afternoon, mixing with snow after sunset before dissipating early Sunday morning. Most areas will see less than an inch of snow due to the short duration of the storm and the relatively mild temperatures, however 3 to 6 inches of snow is possible at pass level.
Southwest winds will increase well ahead of the front today with strong winds expected from the Red Desert through Casper beginning this afternoon. Additionally, strong wind is expected across the Cody Foothills through this afternoon. It will also be dry and warm ahead of the front, increasing fire danger in the low elevation grasses. Today is NOT a good day to burn anything outside, especially along the Cody foothills, and from South Pass to Kaycee, including the Casper area.
A brief period of strong wind will also accompany the cold front as it sweeps east of the Divide. Areas prone to West-Northwest winds like the upper Wind River Basin, northern Johnson County, and the northern Bighorn Basin could see wind gusts around 55 mph with the front this evening.
West winds will also be very gusty along the Interstate 80 corridor late this afternoon into the overnight hours. Strong crosswind will also remain possible across Highway 120 through the Cody Foothills through the evening hours. These strong winds could lead to difficult travel, especially for light trailers and high profile vehicles.
