.KEY MESSAGES...



* Temperatures will increase each day, with temperatures around 15

  to 20 degrees above normal early next week.

.DISCUSSION...Today through Tuesday.



Temperatures across southern Nevada, northwestern Arizona, and 

southeastern California will top out around 10 degrees warmer than 

yesterday as the shortwave responsible for the cooler weather the 

past few days moves out of the region and a ridge of high pressure 

begins to build over the Southwestern US. Temperatures will continue 

to warm each day through early next week, when temperatures will top 

out around 15 to 20 degrees above normal. As temperatures increase, 

we will see widespread Minor to Moderate HeatRisk (Levels 1 and 2, 

respectively) as we head into the weekend. By early next week, we 

will see HeatRisk increase to Major (Level 3 of 4) in Death Valley 

and in the Colorado River Valley. Locally, here in the Las Vegas 

Valley, we see pixels of Major HeatRisk begin to pop up in the 

eastern portions of the valley early next week with a 20 to 40% 

chance of seeing Major HeatRisk across the valley.
