Since Tuesday morning weather models have been hinting at a High Wind Event for this weekend in many parts of Wyoming, especially the southeastern portion. However at 5 days out things could have changed regarding those high winds: they didn’t. The models’ forecast for this weekend in regards to wind has only intensified, especially when it comes to Sunday. There is a possibility for this weekend to be the windiest we have seen so far this fall/winter. It is also looking like the windy and blustery conditions will last well into next week for some locations, especially Cheyenne and Laramie.

The winds will begin to pick up tomorrow morning after a calm and relatively clear night. They will come out of nowhere as they always do: calm one moment, howling the next. For Saturday most locations in southeast Wyoming will be seeing sustained speeds between 30 and 35 mph (for the most part, anywhere could see stronger winds at points in the day) with gusts between 50 and 60 mph. This in itself will be crazy after the snow, and will most certainly close I-80 to Light and High Profile Vehicles due to an extreme blowover risk. Blowing snow and reduced visibility will also be a hazard. I-25 may join I-80 with closures to Light and High Profile Vehicles Saturday as well. Overnight Saturday into Sunday the winds should back off a bit, but come Sunday morning they will be right back.

Sunday is expected to be the windiest day this weekend. Sustained speeds will likely eclipse 40 mph in many locations during multiple points of the afternoon and evening, and wind gusts between 60 and 70 mph are anticipated as well. Some locations could see gusts over 70/80 mph. Expect I-80 from Cheyenne to Rock Springs to be closed to Light and High Profile Vehicles along with I-25 from the Wyoming/Colorado border up to at least Wheatland, but likely up to Douglas. The windy conditions are expected to last into the overnight hours heading into Monday, albeit not quite as strong.

Monday through Wednesday the strong winds will still be here, however not as widespread. Cheyenne, Laramie, and Wheatland will continue to see blustery conditions, however Scottsbluff Nebraska along with Torrington shouldn’t see winds that are quite as strong on Monday and Wednesday. Tuesday looks to be as bad as Sunday, only this time Casper and Riverton will join in the mix with dominant winds coming from the west-northwest, especially in the late afternoon/evening hours. Snow will also be possible with these winds on Tuesday, especially in locations such as Riverton or Casper. Snow chances in Cheyenne for Tuesday are much lower. Things should calm down by Christmas Eve and into Christmas for Thursday and Friday.
