The National Weather Service Las Vegas has issued a forecast indicating a dry and stable week ahead for the Desert Southwest, courtesy of a persistent high-pressure system. "Dry conditions and slowly climbing temperatures are expected this week," the National Weather Service said in a discussion, adding that a weak disturbance would cause increasing north winds especially along the lower Colorado River Valley on Tuesday and Wednesday.
Today through Wednesday, Las Vegas and neighboring areas will bask under sunny skies while temperatures gently rise, the mercury slated to hit figures 3-5 degrees above the seasonal norm during the early part of the week then sees a slight uptick in the following days, a ridge of high pressure is moving over that will be disrupted as another Pacific trough brushes the area Monday, producing a zonal flow and bringing increases in high clouds before conditions stabilize once more. Gusts racing between 20-30 mph may trouble the landscapes from Laughlin-Bullhead to Needles, the National Weather Service alerts.
A peek into the latter part of the week suggests the amplified ridge will linger over the region until the weekend is disrupted by another Pacific trough pushing inland, "Model ensembles show an amplified ridge will hold over the western states Thursday and Friday before another Pacific trough moves inland Saturday and Sunday," outlined the National Weather Service, predicting limited impacts aside from a 20 percent chance of snow in the Southern Sierra and escalating winds over the weekend.
In terms of aviation, Harry Reid International Airport should expect light and variable winds with a north-northeasterly slant by afternoon and westerly winds post-sunset, "Light and variable winds persist through mid-morning, favoring a north-northeasterly direction by 18z," the advisory reads. While the majority of southern Nevada, northwest Arizona, and southeast California will experience light winds and predominantly clear skies, increased gusts will be noticeable along the Lower Colorado River Valley. Cloud coverage will begin to increase from the northwest as the week progresses.
Community spotters are advised to remain vigilant and report any significant deviations or impacts to the National Weather Service as per the standard operating procedures, ensuring that information disseminated is accurate and timely for residents and travelers alike who rely on forecast updates to plan their activities.
