As the Thanksgiving holiday approaches, Las Vegas residents can anticipate a brisk and relatively calm weather pattern courtesy of some steadfast atmospheric dynamics. The National Weather Service Las Vegas indicates that after a cold front sweeps through, skies will clear up resulting in drier conditions and slightly below-average temperatures for this time of year. This change comes as the city finds itself "sandwiched between a central CONUS trough and an eastern Pacific ridge," according to their early morning forecast.
The local boating community should take heed, especially on Thanksgiving Day when "sustained north winds of 15-25 mph and gusts to 35 mph" are expected around Lake Mohave and Lake Havasu, creating potentially hazardous conditions. While a Lake Wind Advisory is already in effect for these areas from 4am through 4pm, due to 2-3 ft waves, "recreation is ill-advised." These conditions are a result of the pressure gradient intensified by the north-south directional winds along the Colorado River Valley, as reported by the National Weather Service.
Going into the weekend and the start of next week, a high pressure ridge is predicted to fortify over the West Coast. This means that while Las Vagas can anticipate warm and dry weather to dominate, occasional clouds might drift in as a weak cutoff low tries to skirt under the ridge. Despite this, the weather should remain uneventful with "a high probability for above-normal temperatures and drier-than- normal conditions" as highlighted by the Climate Prediction Center in their 6-10 day outlook, as detailed by the National Weather Service.
Flight operations around Harry Reid International Airport and neighboring regions can expect some navigational challenges with "lower CIGs to ~5000 feet." However, conditions are projected to improve remarkably after sunrise as the clouds disperse. Windy scenarios will persist through Wednesday, with northerly gusts reaching 20-25 knots in the wake of the front, and should gradually diminish coming into the evening, as per the National Weather Service.
Spotters in the region remain on alert. They play a crucial role, as the National Weather Service depends on their reports to grasp the impacts of significant weather phenomena. This symbiotic relationship between the spotters and the weather service is essential for the provision of accurate, real-time information that benefits the community at large.
