Western US

5 hours ago Alan Smith

A surge of monsoonal moisture will lead to an increase in thunderstorms across the Southwest from Thu to Sun, with UT, CO, & NM favored for the most consistent activity. Northern AZ will see active days Thu-Fri with fewer storms in the days to follow. The Northern Rockies will also see scattered t-storms each day in this pattern. Temps will also not be crazy hot by mid-July standards.
