Las Vegas residents can expect a reprieve from the extended dry spell this coming week, with the National Weather Service forecasting a significant wet weather system to move into the area. According to the NWS Las Vegas office, seasonal temperatures and breezy conditions will start the week, as north winds linger down the Colorado River Valley through this afternoon, with gusts reaching up to 35 mph in certain areas.
Forecasters at the National Weather Service point out "a potent system and accompanying atmospheric river will bring widespread precipitation chances and gusty winds to the region during the second half of the week." This anticipated change in weather could provide one of the wettest periods the region has experienced in quite some time. Las Vegas has gone over 200 days without measurable precipitation, making the forecasted rainfall a notably anticipated event for the drought-stricken area. This moisture comes as part of a broader shift from largely zonal flow to a more amplified weather pattern due to a powerful upper trough affecting the Southwest U.S.
Aviation conditions remain predominantly VFR, with intermittent mid and high clouds expected. While wind variability may cause some disruptions through this morning, the primary direction will be north-northwesterly, with Reid International seeing lighter gusts around 8KT or less. Spotters throughout southern Nevada, northwest Arizona, and southeast California are encouraged by the NWS to report any significant weather or impacts following standard operating procedures.
The latter half of the week, particularly from late Wednesday through late Friday, is slated to be the wettest interval with "probabilities for a half inch of rainfall range from 40-70%," offering hope for a respite in the dry conditions. Not only the rain, but mountain regions like the Spring Mountains and the Sierras may receive substantial snowfall from the incoming system. As the details of this wet storm system continue to coalesce, officials at the NWS suggest residents stay tuned for updates and prepare for the coming rain and potential impact on drought conditions.
