Las Vegas and the surrounding areas brace for a mix of snow, gusty winds, and the potential for rapidly changing weather conditions as a robust storm system sweeps over the region. According to the National Weather Service Las Vegas NV, heavy snow hit the high Sierra today while gusty winds affected the Owens Valley and ridgetops of southern Nevada. The weather forecast anticipates a subsequent shift towards drier conditions and a gradual warming trend over the western states throughout the coming week.
Precipitation is likely to be snatched up by the Southern Sierra, sparing much of our local forecast area with only slight chances of snow. "Although it may appear somewhat promising, precipitation in our forecast area will largely be intercepted by the Southern Sierra again and only 20-40 percent chances of barely measurable snow are indicated by the NBM across the mountains of the Southern Great Basin and Southern Nevada this afternoon," the National Weather Service discussion stated. Despite the minor snow probabilities, the east slopes of the Southern Sierra are expecting accumulations of 4-6 inches at elevations between 7000 and 9000 feet, and possibly up to 12 inches near the crest.
Wind woes are part of the weather narrative with advisories in effect for certain zones where gusts can range from 40 to a whopping 60 mph over higher elevations. Motorists, particularly those traveling in high-profile vehicles, are urged to exercise caution. The winds are expected to "gradually diminish late this evening and overnight as the axis of the upper-level trough quickly pulls away towards the Rockies," as noted in the National Weather Service update. The aftermath brings lighter winds and clearer skies, save for a persistent north breeze through parts of the Colorado River Valley.
Temperatures, nudged by these winds, are expected to climb a few degrees with highs reaching into the 60s across desert zones followed by, little variation on Sunday. Looking ahead, "An inside slider will drop around the ridge on Tuesday, but the models continue to flip-flop on the overall depth of this trough," highlighting the unpredictable nature of weather patterns in this region. The primary effects of these systems will be wind-related, marked potentially by gusty north winds midweek, especially along the Colorado River Valley, as per the National Weather Service.
Aviation-wise, Harry Reid might experience breezy southwest winds with gusts around 20-25 knots by late afternoon. Conditions for pilots are forecasted to be less turbulent by midnight, with CIGs predominantly above 10,000 feet. The overall message to spotters and the public alike remains to stay aware of the evolving conditions and report any significant weather changes as they develop.
