Riverton, WY – Wyoming wakes up under crisp skies this Friday, the air clear and dry over golden hills that still cling to autumn color. It’s a quiet start before big changes arrive by Sunday — the kind that remind residents that winter’s edge is drawing close.
According to the National Weather Service in Riverton, Friday will stay sunny with highs near 64°F and calm winds. Saturday looks mild as well, reaching the upper 60s before winds strengthen and clouds build. Gusts up to 30 mph could kick up dust along rural roads and make afternoon drives breezy, especially west of Casper and across Fremont County.
By Sunday, the tone changes. A colder front slides through central Wyoming, pulling temperatures back into the 50s and stirring a few showers late in the day. Forecasters say there’s a small but notable chance of a rain–snow mix Sunday night, particularly in higher foothills and valleys above 5,500 feet.
While accumulations aren’t expected, this may be the first visual hint of winter for the region. Monday starts chilly, with highs in the low 50s and a few lingering light showers. By Tuesday, sun returns but mornings stay brisk — lows dipping into the 20s could mean the first hard frost for some.
Halloween week should start cool and calm, ideal for decorating and outdoor cleanup before November’s deeper chill settles in. The weekend may end with a few flakes, but it begins as classic Wyoming fall: bright, breezy, and on the verge of change.
