The National Weather Service Las Vegas has provided an update, stating that scattered showers and isolated thunderstorms are expected in southeastern Nevada and northwestern Arizona as a storm system exits. According to the latest forecast from the NWS, San Bernardino is experiencing gusty winds, with peak gusts between 45 and 55 mph. Warmer and drier conditions are expected over the weekend and into early next week, followed by gusty north winds, particularly along the Colorado River Valley, starting Tuesday.
The aftermath of the atmospheric river event resulted in 30 to 40 inches of snowfall on the eastern Sierra slopes, as reported by the National Weather Service. The Spring Mountains received 10 to 20 inches of snow above 7,500 feet, which provided moisture to the dry landscapes below. Barstow-Daggett and Bishop, California, recorded 0.36" and 2.23" of precipitation, respectively, with the latter breaking a daily record that had stood since 1954. Harry Reid International Airport recorded 0.57" of rain, and some Las Vegas Valley locations, including Centennial Hills, measured over 1.00".
As winds gradually decrease following the storm's passage, isolated gusts above 40 mph may still occur, although advisories are set to expire as predicted. The western Mojave Desert and Morongo Basin should remain cautious, as winds could stay elevated through the evening, with the HREF forecasting a 60 to 80% chance of gusts over 45 mph in these higher terrain areas. Light showers and potential thunderstorms, driven by rising CAPE values behind the departing storm system, are expected to move through Nye and Lincoln counties into Clark and Mohave counties, bringing chances for incremental snow accumulation in the mountains, particularly the Spring Mountains and Sheep Range, where an additional 2 to 4 inches may accumulate at higher elevations.
With the worst of the storm past, the skies are expected to clear over the weekend as a transient ridge brings calmer conditions, allowing temperatures to rise. Another shortwave trough from the Pacific Northwest is expected to move into the area by Monday, though it is forecasted to bring little precipitation. Winds may briefly increase across the western Mojave Desert. As the week progresses, despite other systems passing through to the north, the overall trend is for warmer days and calmer skies, according to the long-term forecast from the NWS Las Vegas.
