Area Forecast Discussion

.KEY MESSAGES...



* Strong upper ridging will build into the Western U.S. into early 

  next. This will result in a rapid increase in temperatures, 

  especially this weekend into next week.



&&



.DISCUSSION...

Shortwave trough that brought some unsettled weather and cooler 

temperatures to the region has shifted east as high pressure begins 

to build in from the west. There is still one piece of energy 

trailing this exiting shortwave located over the Rocky Mountain 

states that will bring some enhanced northerly winds to portions of 

northern Mohave, Lincoln, and northeast Clark counties this 

afternoon and evening, but overall winds will be trending lighter 

across the area.



High pressure will build over the region into next week with rapidly 

rising temperatures and dry conditions. Highs today will generally 

be about 10 degrees warmer than Tuesday with temperatures increasing 

through the weekend before likely peaking Monday and Tuesday with 

temperatures some 10-20 degrees above normal for mid-May. In fact, 

many areas may see their first triple- digit temperatures this year 

as we enter the workweek with Las Vegas sitting at a 40% chance on 

Sunday, rising to 90% by Monday and Tuesday. Moderate to Major Heat 

Risk also looks to increase in coverage, especially across Death 

Valley and the Colorado River Valley. As confidence increases we may 

need Extreme Heat Watches and/or Warnings.

.AVIATION...For Harry Reid...For the 12Z Forecast 

Package...For most of the time today and tonight, winds will follow 

typical directional patterns and remain under 8KT. The exception is 

this evening between 03Z-06Z when there is a low chance for 

northeast winds to 10KT to push into the valley. If this did occur, 

winds would switch back to the typical light southwest by 09Z. VFR 

clouds this morning over 15kft will clear with mostly clear skies 

expected through the period. 



For the rest of southern Nevada, northwest Arizona and southeast 

California...For the 12Z Forecast Package...Typical wind patterns 

below 10KT are generally expected across the region today and 

tonight. KBIH into the Owens Valley will see north winds around 10KT 

occasionally gusting 15-20KT this afternoon which will wane after 

sunset. Low chance for a push of west wind at KBIH this evening 

around 00Z, but by 03Z typical north to northwest winds below 10KT 

will return. Skies will be mostly clear through the period.

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
