239 FXUS65 KVEF 262116 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 216 PM PDT Sat Jul 26 2025 .KEY MESSAGES... * Another couple days of below-normal temperatures before the region warms up through the week. * Monsoonal moisture increases in Arizona mid-to-late week, with best chances of precipitation across Mohave County. && .DISCUSSION...Today through Saturday. Dry southwest flow aloft will continue through the remainder of the weekend into the start of next week, resulting in persistent breezy afternoons. In addition to southwest breezes between 15 and 25 mph, the trough across the western CONUS has allowed heights aloft to drop, resulting in below-normal temperatures. This trough will remain situated across the western CONUS, but a ridge of high pressure across the southern CONUS will begin to retrograde westward through the work week. The ridge`s westward progression will allow heights to rise over the Desert Southwest, resulting in at-or-above normal temperatures returning to the region as soon as Monday. The retrograding of this southern CONUS high pressure will also result in an influx of monsoonal moisture up the Colorado River Valley. However, the aforementioned western CONUS trough will contend with the ridge`s westward progression, working to prevent moisture from making it much further west than Arizona. PWATs will increase to around 0.50" across our far southern zones on Tuesday, surging to around 0.75" on Thursday in the lower Colorado River Valley. This moisture lingers through Friday before rapidly retreating. As a result, slight PoPs (15-30 percent) exist for Mohave County Tuesday through Saturday. Of note, due to the dry low- levels and modest moisture flux across northern Arizona, forecast rainfall totals remain less than 0.05" on any given day, making strong gusty wind and frequent lightning the primary hazards next week. Elsewhere, expect dry conditions and mostly sunny skies. && .AVIATION...For Harry Reid...For the 00Z Forecast Package...Similar winds expected today as the last few days, with southerly winds picking up through the afternoon with gusts around 20 kts.
