Las Vegas is expected to have breezy conditions and below-normal temperatures through the weekend. A trough of low pressure off the West Coast is bringing cooler air and southerly winds, according to the National Weather Service.
Dry weather will continue, but there is "a slight chance of thunderstorms in the eastern Sierra slopes of Inyo County" due to a nearby trough, daytime heating, and orographic lift. Storm chances are expected to decrease by Thursday as the trough moves east. A dry southwest flow will continue through the weekend, limiting monsoon moisture. At Harry Reid Airport and nearby areas, clear skies, temperatures near 100°F, and afternoon wind gusts of 20–25 knots are expected. Similar conditions are forecast for southern Nevada, northwest Arizona, and southeast California, with winds easing after sunset except near KDAG, as reported by the National Weather Service.
Early next week, a shift in weather may occur as "the big dome of high pressure which has brought heat to the southeastern states flexes west." This could bring temperatures back to near or slightly above normal. "There is an outside chance of monsoon moisture making it as far west as Mohave County by Tuesday," but it is more likely later in the week. Weather spotters are advised to report any significant weather or impacts as usual. The National Weather Service will continue to provide updates for the public and aviation sectors.
