Las Vegas residents can expect a continuation of isolated showers and thunderstorms today across the broader region encompassing southern Nevada, southeastern California, and northwestern Arizona. The National Weather Service in Las Vegas issued an early morning forecast on September 28, cautioning that although the intensity of the storms is predicted to be less than the ones from Saturday afternoon, the risks of moderate-to-heavy rain, flash flooding, strong outflow winds, small hail, and frequent lightning persist.
Looking ahead, the weather is expected to shift as an upper-level trough approaches the West Coast. According to the National Weather Service in Las Vegas, "An upper-level trough approaching the West Coast will help the low responsible for this weekend's unsettled weather clear out of the region on Monday." This trough is anticipated to usher in breezier winds and drier air, gradually reducing moisture early in the week.
In terms of aviation forecasts, the Harry Reid International Airport is projected to experience light winds with either easterly or variable direction throughout the morning, and only a ~20% chance of thunderstorms in the Vegas Valley during the afternoon. Consequently, thunderstorm mentions have been omitted from the latest Terminal Aerodrome Forecast (TAF). Other areas in southern Nevada, northwest Arizona, and southeast California can anticipate similar conditions, with light daily-pattern winds, except for the Owens Valley which is bracing for southerly gusts of 15-25 knots this afternoon, as detailed by the National Weather Service.
Moreover, tropical activity off the coast is also cited as a noteworthy weather influencer later in the week. "Tropical Storm Narda will continue to slowly meander north, weakening as she moves into cooler waters," the National Service Weather in Las Vegas remarked. It's projected that remnants of Narda will carry increased moisture into southern California and potentially to parts of southern Nevada before another system works to dispel the moisture.
The National Weather Service in Las Vegas has also put out a call to spotters, urging them to report any significant weather conditions or impacts as they usually would. The provided information helps meteorologists keep a comprehensive outlook on the evolving weather patterns, ensuring that forecasts remain as accurate and updated as possible for the well-being of the communities across the affected regions.
