.KEY MESSAGES...

  than normal temperatures returning as we head into the weekend

  and sticking around into early next week. 



* Moisture will slowly return to the region next week, resulting

  in increasing thunderstorm chances for portions of the area.

.DISCUSSION...through next Thursday. 



Weather over the next few days will remain relatively benign as a 

ridge of high pressure slowly nudges into the region. These slowly 

increasing 500 mb heights will allow for our gradual warming trend 

to continue through early next week. Warmer than normal temperatures 

will return to southern Nevada, northwestern Arizona, and 

southeastern California as we head into the weekend, resulting in 

widespread Moderate (Level 2 of 4) HeatRisk. Moderate HeatRisk means 

that this level of heat will impact heat sensitive individuals, 

individuals that have not acclimated to the heat, and those without 

access to effective cooling and/or adequate hydration. Temperatures 

across the region will peak on Monday, with a few patches of Major 

(Level 3 of 4) HeatRisk popping up in the Colorado River Valley, 

Golden Valley, and the lower elevations of the Big Sandy Wash.



While the ridge of high pressure slowly pushes into the area, a 

trough will develop off the coast of California over the weekend. 

This set up will result in southerly flow across the region next 

week, which will result in increasing moisture across Mohave County 

that will then spill into southeastern California and southern 

Nevada. Confidence regarding next week's increase in moisture is 

high, however the exact details regarding locations of individual 

storms and precipitation amounts remain blurry due to interensemble 

variability. Precipitation totals will be dependent on how much we 

see moisture increase, which will be dependent on the orientation of 

the trough relative to the ridge as it pushes into the area. With so 

many moving parts, make sure to stay tuned to the forecast as it 

continues to evolve.
