CHEYENNE, Wyo. (Wyoming News Now) - Cheyenne escaped a small storm as they developed northeast of the Capital City this afternoon. The west and south portions of Wyoming saw much more weather in the form of isolated rain showers and thunderstorms carry into the evening hours. For Sunday, the thunderstorm outlook does not change much with the exception of general thunderstorms extending further east a bit into central Wyoming. This is due to the monsoon moisture being pulled from the southwest part of the country into the state of Wyoming. Cloud coverage will increase around noon and showers will develop soon after.

All of this is good news for the region as the smoke forecast draws smoke from Idaho and brings it into Wyoming with northerly to northwesterly winds. Though light in smoke density, the combination of weather elements can reduce particulate matter in the afternoon hours with the occurrence of rain. This can improve areas like Yellowstone that have been measuring Moderate levels in the Air Quality Index for the last several days. Temperatures will warm slightly going into Sunday with a wide variance across Wyoming. Places like Sheridan will near 100 with low to mid 90s in the region while west and south Wyoming are mostly in the 70s due to the weather forecasted.
