Severe Thunderstorms and Strong Winds Expected in Casper, WY
Residents of Casper, Wyoming, and surrounding areas should prepare for a day of unsettled weather on Saturday, August 29, 2026. According to the National Weather Service (NWS) in Riverton, a persistent monsoonal pattern is bringing high atmospheric moisture levels to the region, with dew points in the 50s and precipitable water values nearly double the seasonal average. Strong afternoon and evening thunderstorms are expected across southern and central Wyoming, with localized damaging wind gusts of up to 75 mph, hail, and wet microbursts possible. Cloud cover in the morning may limit instability in some areas, but an approaching cold front will keep the potential for severe weather elevated into the night. A brief cooling trend is anticipated on Sunday as the cold front moves through, bringing drier and cooler air to the region.
