Las Vegas is bracing for the first significant winter storm of the season, with snow and rain expected to impact the area today and tomorrow. According to the National Weather Service, elevations above 4500 feet are likely to experience at least minor snow impacts that could affect major travel routes like Interstate 15 and Highway 95. Forecasts predict dry conditions to return by midweek after the precipitation ceases.
"The first real winter system of the season was already producing snow in the Owens Valley early this morning," stated the National Weather Service. While snowfall is a primary concern, the Mojave Desert may see a prominent dry slot on Monday which raises questions about the possibility of precipitation shutting off or the development of convection within it, potentially disrupting snow forecasts.
Travelers and residents are urged to stay informed of the weather conditions. Winter Storm Warnings and Winter Weather Advisories remain in effect, as previously reported by the NWS, with an eye on the need to possibly extend the Advisory for Mohave County by Tuesday. The storm has been observed to slow in its approach, indicating the advisories may be prolonged into the week if this trend continues.
Ahead of the storm, light winds and increased cloud coverage are forecasted for Las Vegas, with chances for precipitation rising this afternoon and evening. "Showers will be intermittent this afternoon before conditions deteriorate late tonight into Monday with periods of rain and ceilings 4-5 kft AGL," relayed the National Weather Service. For aviation, this could mean reductions in visibility and ceilings, with general winds staying below 10 knots tonight and into tomorrow across the region.
For those in the Las Vegas area, the impending weather might bring an end to a lengthy dry spell; Saturday marked the 196th consecutive day without measurable rain. Depending on when the first measurable rain occurs, this streak could be the second-longest such record at KLAS, next only to the 240 consecutive dry days witnessed in 2020. Spotters are advised to report any significant weather or impacts, ensuring the National Weather Service stays updated on the ground situation.
