Wyoming Heat Wave Continues But Will Finally Break On Friday

After days of 100+ degree temperatures in some parts of Wyoming, a Canadian cold front will bring high temperatures down more than 50 degrees on Friday.

When is it going to cool down? 

Wyoming meteorologist Don Day said that’s the question he has been getting constantly over the last week

There’s a reason for that. High temperature records have been shattered across the state from Casper to Cheyenne and Lander to Laramie. 

The heat streak is about to be broken, however, and temperatures are going to fall — a lot, according to Day.  


Greybull, Thermopolis, Worland, Buffalo, Kaycee, and many other communities have recorded record-breaking temperatures in the low 100s. 

Even Big Piney, which claims the moniker ‘Ice Box of the Nation,’ topped 90 degrees earlier this week. 

And to make things even more uncomfortable, wildfires from Idaho and Oregon have created smoky conditions in the hottest parts of Wyoming. 

Of course, Day can’t fix the weather but he’s a perfect target for the complaining.

Here Comes The Cold

The good news, Day said, is a cold front from Canada is expected to move into the Cowboy State Thursday night and Friday. 

With that, temperatures should drop by more than 40 degrees in some areas. In fact, some parts of the state could struggle to get past 50 degrees on Saturday. 

“Here comes the first taste of fall,” Day said in his Cowboy State Daily weather forecast. 

Day said the high temperature in Cheyenne will be 50 degrees, 53 in Laramie, and 55 in Casper. 

In Greybull, where the high temperatures have settled in the low 100s for days, the cold spell is likely to drop high temperatures to 62 degrees on Friday and 66 degrees on Saturday. 

Buffalo, Wyoming could see a 50-degree drop in the high temperature as Saturday, it is only expected to reach 51 degrees. 

Even Snow

The cold front could bring snow to the Big Horn mountains on Friday night but Day said not to expect too much. 

“It doesn’t look like a really big early fall storm, but certainly enough to grab everybody’s attention, especially after all the heat,” Day said. 

Don’t Buy The Hyperbole

What likely will also be grabbing national attention, he said, will be Hurricane Kay’s impact on southern California. 

The remnants of the hurricane is are expected to bring an end to the heat wave that has wreaked havoc on the California’s power grid.

Day said to watch out for how the hurricane is being portrayed. 

“I guarantee you will hear on the news that this has never happened before,” Day said of the hurricane impacting California. 

“But this is crazy talk. It has happened several times before,” he said, mentioning that the remnants of Hurricane Kathleen, in 1976, is a most notable example. 

“Weather patterns repeat themselves,” he said. “Weather patterns do the same things over and over again spread out over time.”
