653 FXUS65 KVEF 082255 RRA AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 355 PM PDT Tue Sep 8 2026 .KEY MESSAGES... * Above-normal temperatures expected mid-to-late week. * Breezy south-southwesterly wind gusts expected across the region Friday through the weekend. && .DISCUSSION...Today through Monday. High pressure over the southern US will gradually expand and strengthen over the Desert Southwest mid to late week. This will result in rapidly warming temperatures Wednesday and Thursday with temperatures climbing to around 8 to 10 degrees above normal. As a result, an Extreme Heat Warning has been issued for Thursday for Death Valley, the Las Vegas Valley, Pahrump Valley, Moapa Valley, Colorado River Valley, southern Mohave County, and southeastern San Bernardino County. Temperatures will begin to trend downward starting Friday as a trough pushes into the western US. This will allow temperatures to drop about 5 degrees Friday along with an additional drop around 2 to 4 degrees Saturday with temperatures close to normal by early next week. Generally dry conditions are expected, but some weak monsoonal moisture will be pulled northward Wednesday and Thursday allowing for at least a slight chance of thunderstorms in the Sierra and terrain of the southern Great Basin due to strong daytime heating and weak instability. The aforementioned trough pushing into the western US will bring cooler temperatures but also bring increasing southwest winds to the region. The strongest winds look to occur Saturday afternoon where widespread gusts 25-35 MPH are expected, with over a 50% chance of gusts over 40 MPH in the western Mojave Desert. There could also be some gusty southerly winds impacting Lake Mohave and Lake Havasu this weekend, which could impact boaters with winds and waves. && .AVIATION...For Harry Reid...For the 00Z Forecast Package...Light winds generally following typical diurnal directional trends will continue through tomorrow.
