Areas of Extreme Heat and Fire Weather in the West; Refreshingly Cooler Further East

Extreme heat will continue across the Pacific Northwest into midweek before finally waning. Hot temperatures, low relative humidity, gusty winds, and isolated dry thunderstorms will bring critical fire weather into Tuesday.

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.
