.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.

.AVIATION...For Harry Reid...For the 00Z Forecast Package...A

generally diurnal wind pattern will take hold as high pressure

begins to build into the region. A couple more hours of

east/southeast winds with occasional gusts to 15 knots is expected

with a gradual shift to a more south/southwest direction by

03z-04z. Winds will then remain southwesterly overnight, becoming

variable by 10z-12z before shifting to the north/northeast by

sunrise Thursday. Temperatures will continue to climb each day 

with a 50% probability of reaching 100 degrees as early as Sunday 

afternoon.





For the rest of southern Nevada, northwest Arizona and southeast

California...For the 00Z Forecast Package...A generally diurnal

wind pattern will persist with winds remaining 10 knots or less

most terminals. The one exception will be KIFP, where northerly

winds will increase by 12z-15z Thursday with gusts occasional 15-20

knots. Otherwise, expect winds up to 10 knots during the

afternoon/early evenings becoming variable overnight.
