Heat Persists in the Southwest; Elevated to Critical Fire Weather in the Great Basin; Poor Air Quality in the West

Dangerous heat will persist across the Southwest U.S. through this week, easing by next week. The heat will focus further east in the Great Plains and Mississippi Valley beginning next week. Elevated to locally critical fire weather conditions will persist for the Great Basin today. Poor air quality lingers for the Northwest, Great Basin, Central Rockies into the Plains. Read More >

High pressure will remain southeast of the Four Corners the rest of the weekend and continue drawing subtropical monsoon moisture into southern Colorado and Utah. Expect an increase in showers and thunderstorms Sunday with gusty outflow winds, small hail and brief heavy rain possible with storms. The best potential for heavy rain should occur across southeast Utah and southwest Colorado where the better moisture resides and scattered thunderstorms are forecast. Drier air moves back in Sunday evening and will remain through next week. Southwest winds aloft will help keep wildfire smoke out of much of the region, with the exception of extreme northeast Utah and northwest Colorado, where a more westerly component will keep the southern edge of the smoke in this region.
