FXUS65 KVEF 230543 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 1043 PM PDT Sat Aug 22 2026 .KEY MESSAGES... * Above normal temperatures continue through next week. * Isolated storm chances linger into early next week, with best chances in northwestern Arizona and the southern Great Basin. && .DISCUSSION...through Friday. Hotter than normal temperatures will continue through the forecast period as a broad ridge of high pressure remains positioned over the area. High temperatures will top out around 2 to 7 degrees above normal each afternoon, with day to day variations depending on the position of the ridge, cloud cover, moisture, etc. Overnight low temperatures will run around 3 to 8 degrees warmer than normal, providing little-to-no overnight relief in the lower elevations of the Mojave Desert where temperatures will bottom out in the mid-80s to mid-90s. Given the long duration of this anomalous heat, we will see widespread Major-to-Extreme (Levels 3 and 4 of 4, respectively) HeatRisk return during the second half of the week. Southwesterly flow aloft will continue to dry things out, with precipitable water slowly decreasing across the region over the weekend. As a result, storm coverage today and tomorrow will be more isolated in nature, and will be limited to the higher terrain of the Southern Great Basin, Eastern Sierra, and the Arizona Strip where there is a 10 to 30% chance of precipitation this afternoon. Localized moderate-to-heavy rain, lightning, and erratic outflow winds will be the primary threats with any storms that develop. Ensemble guidance continues to show a relative uptick in moisture across northwestern Arizona on Monday. Currently, this slight increase in moisture is reflected in the scattered 15 to 30% rain chances in Mohave County on Monday afternoon. Drying will resume on Tuesday, continuing through the end of the week as we find ourselves under southwesterly flow aloft. && .AVIATION...For Harry Reid...For the 06Z Forecast Package...
