Cooling Trend Warms as Weather Exits East

CHEYENNE, Wyo. (Wyoming News Now) - Weather is much more favorable lately after the heat wave finally loosened its grip this week. Going from record high temperatures to frost advisories shows how volatile the weather can be. With the heat behind us, we can look forward to more fall-like temperatures in the near future as a cold front was able to break the high pressure blocking pattern that starved the region of moisture and brought unbearable heat. Clouds continue to clear Saturday evening and weather is a non-factor the next few days. Clouds will return early Tuesday morning in the western part of Wyoming ahead of the next encroaching cold front by mid-week. Currently, there is a frost advisory over Shirley Basin, Upper North Platte River Basin and Laramie County until 9am Sunday.

Smoke is also a cause for concern as eight Moderate Air Quality Index smoke measurements are in western Wyoming. Denser smoke from Idaho will move east over the weekend into southern Montana and then start to seep into northeast Wyoming much like last weekend. Monday, the wind direction will shift from the northeast causing the increase in smoke particulate matter. Wind speeds are low the next few days across the state which is good as we are not looking for a return of smoke anytime soon.

Temperatures are cool Sunday and start to gradually warm going into the week. The extended weather pattern is looking more predictable in terms of cold fronts and cooler temperatures as we exit the summer weather of instability and have cold fronts that go south enough to bring polar air from the north.
