Final Day of Excessive Heat in the Desert Southwest
One more day of excessive is ahead for the Desert Southwest as a ridge of high pressure sits over the area. The heat could be dangerous for cities like Las Vegas. Temperatures region wide will stay above average with many spots 5-10° warmer than normal.
This is the final day of intense heat, with the mercury hitting 110 to 115 in some areas of the Mohave Desert.
The heat will start to break by Tuesday for many locations, but it will still be seasonally hot. Temperatures will return to around average.
The upper level ridge has been inhibiting monsoonal moisture across the Four Corners region. As the remnants of Nora move northward, this will bring in the “cooler” temperatures and much needed rainfall, but the threat for flooding.
