Northerly winds reaching 30 to 40 mph will impact the Colorado River Valley and Lake Mohave today, causing waves up to 3 feet, with no wind advisories issued. Winds will calm later in the evening, with lighter winds across the rest of the region. Next week, a high-pressure system will raise temperatures above seasonal averages, with Las Vegas desert valleys reaching the mid-to-upper 70s and Death Valley approaching the upper 80s, according to the National Weather Service.
The week will remain warm, with "Minor" HeatRisk advisories in effect for heat-sensitive individuals in regions including the Las Vegas Valley and Death Valley. Outdoor activities in these areas may require extra hydration and cooling. A weak shortwave from the northwest is expected to move into the Great Basin Desert, bringing slightly cooler temperatures. However, winds may keep temperatures elevated. Forecast models indicate a potential for precipitation late next week, as a closed low-pressure system could approach from off the coast with southwesterly moisture, which may lead to rain in parts of the Mojave Desert, as reported by the National Weather Service.
At Las Vegas's Harry Reid Airport, northerly winds will shift to lighter breezes on Saturday morning, with "no operationally significant clouds or weather expected." Southern Nevada, northwest Arizona, and southeast California will also see lighter winds as stronger gusts in the Colorado River Valley decrease. Temperatures in Las Vegas are expected to rise toward summer-like levels into the weekend and next workweek, as stated by the National Weather Service.
