CHEYENNE, Wyo. (Wyoming News Now) - As a beautiful weather weekend concludes, we prepare for lithometers (smoke) opposed to hydrometers (rain) to start our weather week. Smoke and haze will pose a problem to those with breathing sensitivities outdoors Monday and Tuesday across much of Wyoming as westerly winds bring smoke in from the west and winds shift from the northeast in the northeast part of the state pulling the plume down across eastern and central Wyoming. Temperatures will warm Sunday to Monday about 10 degrees for high temperatures to the 80s in Wyoming and low 90s in west Nebraska. Low temperatures are mostly in the 40s.

Winds will be light the next few days. Brief gusts in the low 20mph range are possible in the afternoon hours. Wind direction plays a more significant part as wildfires from the north and west make their presence felt as smoke will fill into Wyoming over the next couple days. Currently, the northwest part of the state is exhibiting Moderate air quality measurements by the air quality index. Locations include Evanston, Yellowstone, Jackson and Sheridan. These locations are likely to degrade and increase in number over the next 24 hours.

The weather pattern is starting to become more predictable as cold fronts are able to sweep through the state having cold air behind it reach Wyomingites. Previously, the high pressure and blocking patterns over the southwest would dominate the region preventing lows from entering. That is starting to change as Fall approaches. High temperatures in the 80s and lows in the 40s and 50s will persist until rain for much of Wyoming arrives Wednesday afternoon.
