Wyoming: September Starts and Summer Ends Hot, Dry, and Dangerous

Summer isn’t over yet – there will be intense heat, persistent dryness, and possible record-setting high temperatures throughout Wyoming during the first two weeks of September.

The National Weather Service Office in Riverton has analyzed current weather patterns and found a hot trend. All of Wyoming will feel the heat from the last days of August into the first days of September.

“The resurgence of typical summertime weather is likely in the coming weeks,” reads a Facebook post from the N.W.S. Riverton Office. “This means it will be hot and dry.”

If this weather pattern stays in place, Wyoming communities may have to endure new record-high temperatures for September.

The N.W.S. Riverton Office says the heat is due to a high-pressure system descending on Wyoming for the first half of September. Nearly every state will experience some hot temperatures, but Wyoming will experience the worst.

There are several hazards with such weather. Hot, sunny days increase the chance of heat stroke or exhaustion. In addition, the dryness that comes with the heat will increase fire danger throughout Wyoming.

However, the “good news” is that Wyoming is also expected to undergo a more intense winter. At the beginning of 2023, the state will receive above-average snow, possibly accompanied by below-average temperatures.

Summer 2022 officially ends on Thursday, September 22.
