The National Weather Service in Las Vegas has issued an advisory for the Las Vegas area, warning residents about incoming gusty winds and a notable drop in temperatures. According to the NWS forecast, a large low pressure system is set to bring strong south to southwest winds to the region from today through tomorrow, coupled with a “significant cooling trend.”
Wind gusts may reach up to 45 mph, leading to Wind Advisories effective this evening until tomorrow evening for parts of the Mojave Desert, Death Valley, and Nye County. The NWS warns these conditions mark the "first widespread gradient wind event with gusts over 40 mph of the fall season," which will introduce cooler temperatures with highs in the lower 80s and lows dropping to 55-60 degrees in the Las Vegas Valley by tomorrow night. Las Vegas residents can therefore expect a shift in the weather from the usual heat to a brisker climate expected for the time of year.
In addition to winds, there’s also a chance of light showers and even isolated thunderstorms, primarily focused in northern Inyo, Esmeralda, and central Nye counties come tomorrow. While the wind might be the main event, the possibility of precipitation—however slight—is something to keep in mind. And for those residing in higher elevations, namely above 9,000 feet in the Sierra and White Mountains, don't be startled if you see a dusting of snow.
Flying out of Harry Reid or navigating the airspace over the southern Nevada, southeastern California, and northwestern Arizona might also be a test of patience and skill. Pilots should brace for “hazy skies” which may “reduce slantwise visibilities,” says the NWS advisory, due to the ongoing southern California wildfires, although no operationally significant cloud cover is predicted outside of KBIH. Those traveling or working outdoors should take all necessary precautions in light of the wind advantages and visibility impediments.
The weather this week is under the tyranny of Mother Nature's whims, with lighter winds anticipated by Tuesday as the system moves on, but leaving a chill in its wake. Another low from the Pacific Northwest is forecasted to reinforce the cooler temperatures and may bring its own share of gusty conditions and precipitation chances. The National Weather Service encourages spotters to report any significant weather or impacts according to standard operating procedures.
