Las Vegas is set to experience a week of changing weather patterns, according to the latest forecast from the National Weather Service. The report, published early on March 1st, anticipates a series of upper-level storm systems that will bring about varying chances of precipitation and gusty winds to the region. The National Weather Service highlights, "A third system will move into the region later in the week, bringing a better chance of more widespread precipitation."
The system later today isn’t expected to bring significant weather. The pressure gradients will stay south, and with limited moisture, only light showers are possible in eastern Mohave County. Cloud cover will increase through the afternoon and evening, but that’s the main change. Moisture levels will be near normal, but rainfall will likely be very light, as per the National Weather Service.
Starting Sunday, a low-pressure system will move through northern California and the southern Great Basin by Monday. This will bring a better chance for light rain north of Las Vegas and mountain snow, with precipitation chances between 60 and 80%. Snow levels are expected to drop to around 4000 ft late Sunday. The heaviest snowfall is expected in higher areas of Lincoln, central Nye, and Esmeralda Counties, with up to 3 inches possible. The National Weather Service has issued a Wind Advisory for the Western Mojave Desert, which may expand depending on how the weather develops.
As for the long-term outlook, the weather continues to shuffle, with a brief respite on Tuesday before the next weather system rolls in on Wednesday. Agreement among models over timing has improved, although there's still some uncertainty around the exact dynamics. Precipitation is anticipated to be modest, with valley areas seeing less than a 30% chance for significant rainfall and higher chances confined to elevated terrain. Winds will peak on Thursday, aligning with the back end of the trough. According to the National Weather Service, "There are some probabilities over 50% areas further east, however currently they are more isolated, and the signal is not as strong."
Aircraft operations could be impacted as early as Saturday night with a 50 percent probability of escalated winds at Harry Reid airport, as per the National Weather Service's aviation forecast. By Sunday afternoon, much stronger southwest winds will grace the region, signalling pilots to brace for potentially choppy conditions. Across the broader southern Nevada, northwest Arizona, and southeast California, similar patterns are expected, with no immediate operational impacts from cloud cover.
Meanwhile, spotters have been advised to stay vigilant and report significant weather changes or impacts, playing a key role in tailoring the National Weather Service's ongoing safety measures. As the week unfolds, and the storms play their hand, the potential for wetter, windier days seems on the horizon, yet thankfully with no anticipation of extreme events.
