CASPER, Wyo. — The forecast remains mostly clear for Casper during Sunday night’s “blood moon” eclipse, according to the National Weather Service in Riverton.
There is a 25% chance of maximum cloud cover in the Casper area, said meteorologist Chris Hattings in a video brief Friday. The Bighorns and Hot Springs County may see cloud cover at 45% of maximum, with up to 60% cloud cover possible in the Yellowstone area.
“Disclaimer here: We can’t pinpoint every single cloud that’s going to pop up,” Hattings said.

In Casper, a high of 73 is expected Sunday, with an overnight low of 44 and 6–14 mph winds.
Though Wyoming will miss the very first part of the eclipse, the total eclipse will last until around 11 p.m. and a partial eclipse will last until shortly before midnight. People wanting to catch the eclipse should look to the east-southeast at around 8:30 p.m. Sunday, according to Hattings.
The eclipse occurs when the earth passes between the moon and the sun, casting a shadow on the moon. The longer wavelengths of sunlight that pass through the earth’s atmosphere give the “blood moon” its reddish hue, according to NASA.
