Labor Day heat wave, cooling trend late next week
A significant late-season heatwave will persist across the West throughout the holiday weekend before eventually relenting mid to late next week. Daily record highs are likely across much of the West and some areas will break Sept monthly records as well. Smoky conditions have also become more widespread across the Northwest & Northern Rockies. Cooler temps will finally arrive late next week.
