The weekend weather forecast for the Las Vegas area presents a tale of two different weather patterns. While the western Mojave Desert and western Great Basin are expected to experience dry and breezy conditions, areas to the east, specifically the eastern Mojave Desert and northwest Arizona, are anticipating increased moisture and thunderstorm activity, according to the National Weather Service.
A red flag warning remains in effect for Esmeralda and Nye counties due to the anticipated critical fire weather conditions, according to National Weather Service. Along with gusty winds, the area has a heightened concern for potential fires. "Strong winds will be a concern due to the aforementioned stronger winds aloft potentially being mixed down by any storms," the forecast discussion states.
As for the city, South winds are expected to prevail for the rest of the overnight period with speeds around 8 knots at Harry Reid International Airport. "Most likely, it will be dry through the TAF period with no thunderstorm impacts at the terminals," National Weather Service report detailed. Though there's a low chance for scattered precipitation early this morning through southern Nevada, thunderstorm chances for the afternoon appear minimal at the airport as most convection will be to the east of the terminal.
Heading into the work week, conditions across the region will shift, with decreasing precipitation chances and rising temperatures. The excessive heat won’t be solely confined to the daylight hours. "The encroaching 500mb high will also act to raise temperatures at the surface, with forecast highs 3-6 degrees above normal," says National Weather Service. This brings along "widespread Moderate HeatRisk with patches of Major in the Las Vegas and Colorado River Valleys." As we forge into midweek, the potential for weather disturbances with fluctuating moisture and precipitation chances lies in the balance, contingent on the interplay between different forecasted weather systems.
For the aviation sector, the National Weather Service report warns of gusty south winds with the possibility of thunderstorm-related sudden gusty winds, lightning, and ceiling heights ranging from 8,000 to 10,000 feet. Pilots will need to remain vigilant, especially during afternoons when breezy conditions prevalent. Spotters, meanwhile, have been encouraged to report any significant weather events as they unfold through the weekend.
