Las Vegans can expect a brief period of calm weather today, with near-normal temperatures in the mid to upper 50s. However, a Pacific system is set to bring snowfall and strong winds starting Saturday. The National Weather Service in Las Vegas reports that a Pacific trough, currently over the Gulf of Alaska, will move inland, bringing significant snowfall to the Southern Sierra and strong winds to parts of Nevada.
According to the National Weather Service, the incoming system will bring most of its moisture to the Sierra, although southern Nevada may experience a 30-50 percent chance of precipitation, with snow levels ranging from 5,500 to 6,500 feet. Snowfall is expected to be less than an inch, posing little impact to Las Vegas's grounded establishments. Meanwhile, gusts of 40 to 55 mph are forecast to affect the Owens Valley, particularly impacting high-profile vehicles along Highway 395.
Weather conditions are expected to improve by Sunday as a high-pressure system brings sunny skies and milder winds, except in the lower Colorado River Valley, where north winds could gust up to 20-25 mph. This will be a brief reprieve before another shortwave targets the Pacific Northwest early next week. Like previous systems this season, it will deposit most of its moisture before reaching the Sierra, sparing much of Southern Nevada from heavy rainfall.
The National Weather Service reports that strong ridging is expected to build across the Western US, with the ridge axis overhead by late in the week. This suggests an extended period of dry weather, with temperatures gradually rising above seasonal averages. Las Vegas's dry streak is expected to continue, preserving its arid reputation for at least another week.
Harry Reid International Airport and surrounding areas are expected to experience some clouds with bases above 12,000 feet and light winds, typical for the daily cycle. KDAG will see the strongest winds, with westerly breezes of 10-20 knots until early afternoon. Spotter activities are encouraged to report any significant weather impacts, in accordance with the standard operating procedures.
