As the remnants of the latest weather system continue to pass through the Las Vegas region, residents are facing continued snow and gusty winds but should expect a return to normal conditions over the coming weekend. According to the National Weather Service Las Vegas NV, precipitation is expected to persist through tonight with snow levels above 7500 feet in the Spring Mountains witnessing accumulations between eight and 16 inches, prompting a Winter Storm Warning until midnight PST tonight. The Sierra and White Mountains should see the last of the snow taper off by afternoon as reported by NWS.
The weather outlook for the Las Vegas area detailed in the NWS forecast discussion emphasizes a shift towards drier conditions over the weekend, and a potential system that might affect the area mid-week. Following the precipitation, an upper-level trough will move on, to be replaced by dry northwesterly flow aloft. This pattern will likely induce gusty northerly winds especially in the Colorado River Valley, where Bullhead City and Needles could experience gusts over 40 mph on Sunday and Monday. As for temperatures, they're anticipated to drop several degrees below average on Sunday, with gradual increases expected as we move into Monday and Tuesday, though atmospheric inversions may keep colder air in some deeper valleys.
Looking ahead, the forecast is observing a low pressure system off the Baja California coast. It is anticipated to draw moisture inland over central Baja Peninsula, then moving north through Arizona before possibly reaching the Mojave Desert. However, the details pertaining to this are currently murky, with ensemble models showing a slower movement, which suggests precipitation might hold off until after next Thursday. "Ensembles show moisture moving inland over the central Baja Peninsula, then moving north through Arizona before reaching the Mojave Desert," the NWS report states, but also admits the overall confidence in this forecast remains low at this stage.
As for aviation interests, VFR conditions are expected to return areawide by late morning, following a period of light rain showers through the overnight period and potential visibility reduction amidst heavier showers. The NWS advises that winds at Harry Reid will remain southerly to southwesterly with speeds around 8-12KT transitioning to lighter speeds under 8KT by mid-morning. A northerly wind shift is also anticipated, with an uptick in winds later in the period. In areas such as eastern San Bernardino, Clark, southern Lincoln, and Mohave counties, the persistence of showers and mountain snow into the dawn hours is expected. "Winds will generally be southerly to southwesterly with speeds around 10-12 knots tonight, dropping to 5-10 knots Saturday," according to the forecast.
Weather aficionados and residents alike are encouraged to keep their eyes on the horizon and report any significant weather or impacts, maintaining the community's preparedness for the changing winter conditions the region is currently experiencing.
