The National Weather Service in Las Vegas expects cooler temperatures and "Breezy southwesterly winds" as a shortwave moves across the Great Basin. Winds will increase today and continue through tomorrow, with gusts of 30 to 40 mph in the western Mojave Desert. Skies will be mostly sunny to partly cloudy, with mid-to-high level clouds over southern Nevada, southeast California, and northwest Arizona. Similar conditions are expected on Thursday, according to the National Weather Service.
A deep trough will move inland from the West Coast starting on Friday, bringing gusty winds and "sharply cooler temperatures Saturday and Sunday." Light rain and high-elevation snow are possible in the Sierra and southern Great Basin, with a small chance of isolated showers in Las Vegas. "Heights will gradually rise as the weekend trough departs," and temperatures are expected to be "returning to near normal or slightly above normal by midweek," as reported by the National Weather Service.
South to southwest winds are expected today at Harry Reid Airport and surrounding areas, with gusts reaching 20 to 25 knots this afternoon. Similar conditions are forecast for southeastern California, southern Nevada, and northwest Arizona today and Thursday. Winds are likely to weaken overnight, except near Barstow, where breezy conditions may continue. The National Weather Service is asking spotters to monitor conditions and report any significant developments.
