Up to 8 inches of snow possible in Cheyenne in Thanksgiving storm

(Dan Cepeda, Oil City News)

CHEYENNE, Wyo. — Cheyenne could see as much as 8 inches of snow in a Thanksgiving snowstorm that is capable of bringing 20 or more inches to the Wyoming mountains.

The National Weather Service in Cheyenne has issued a winter storm warning, in effect from 5 p.m. today through 5 a.m. Saturday, Nov. 25. It warns of snow accumulation in Cheyenne of 4–8 inches and winds gusting as high as 50 mph along Interstate 80. That could create patchy, blowing snow, significantly reducing visibility. Windchills could dip as low as minus 20, meteorologists warn.

Today’s forecast calls for a mostly cloudy start to the day. The high will reach 32 degrees, and winds will come from the north-northeast at 5–15 mph. A 40% chance for snow sets in after 3 p.m. There is a 100% chance for snow overnight as the temperature dips to 8. Windchills will be between minus 5 and 5 degrees. Up to 5 inches of snow overnight is possible.

Friday will continue a 90% chance for snow, although that should fall to 60% through the day. There’ll be a steady temperature around 12 degrees. Windchills will be between minus 10 and 0 as winds come from the southeast at 15 mph. An additional 3 inches of snow is possible during the day.

Overnight, there’ll be a 50% chance for snow. Skies will otherwise be mostly cloudy, and the low will fall to around 3. Windchills will again be between minus 5 and 0 as winds come from the southeast at up to 10 mph.

“As the snow showers and breezy winds slowly subside by Friday afternoon and evening from north to south, the conditions that will be apparent are the bitter cold temperatures and wind chills,” meteorologists wrote in the forecast discussion. “Daytime highs will struggle to get out of the single digits to teens for Friday. Sub-zero wind chills are expected across the forecast area.

“Areas that see the strongest wind gusts on Friday will also experience wind chills of -5F to -15F. While this is not meeting criteria for wind chill headlines, it is still important to mention due to the potential exposure of humans and agriculture outdoors. For those that plan to shovel the new snowfall, make sure to bundle up in an extra layer or two while doing so.”

There will be a 20% chance for snow on Saturday morning, which should subside by noon. The skies will be partly sunny, and the high will return to about 22 degrees. Saturday night will see mostly clear skies and a low near 11.

Sunday’s forecast calls for a high of 34 under sunny skies. Temperatures will rise to a high of 36 on Monday under sunny skies. Sunny skies continue Tuesday and Wednesday with highs near 44 degrees.
