Las Vegas residents can expect a continuation of dry weather, with only a minimal chance of showers in some parts of Mohave County, according to the latest forecast. The brief break from the persistent north winds will soon come to an end, with those winds expected to return early next week as more storm systems move in from the north. While sunny skies will dominate much of Southern Nevada, temperatures will drop, bringing cooler conditions to the region. According to the National Weather Service, Las Vegas might see lows near 30 degrees Fahrenheit by Tuesday morning.
In their Area Forecast Discussion, the NWS outlined that while most of the colder air from a dipping polar trough will remain east of the region due to the Rockies, Las Vegas can still expect cooler temperatures. The western edge of the trough is projected to affect the eastern Great Basin and Four Corners, potentially leading to the development of a cool, strong surface high over the Great Basin. Forecast models show some variation, with the Global Ensemble Forecast System (GEFS) suggesting warmer conditions compared to the European Centre for Medium-Range Weather Forecasts (ECMWF) and Canadian models. However, the National Blend of Models (NBM) is leaning toward the cooler outlook, which should be considered when planning for the week ahead.
In aviation-related updates, the NWS indicates that at Harry Reid airport, wind will not exceed 10 knots and is expected to follow typical diurnal patterns. For other regional airports, similarly light and variable winds are forecasted with the exception of the Colorado River Valley where gusts might reach 20 to 25 knots. The NWS also highlighted in their discussion that "The Colorado River Valley TAF sites will see 10 to 15 knot sustained northerly winds through the afternoon," with the suggestion for pilots to prepare for breezier conditions.
Spotter activity remains an important component of weather forecasting, as it provides real-time, on-the-ground data. With cooler temperatures and breezy conditions anticipated, the National Weather Service's Spotter Information Statement advises local weather spotters to report any significant weather events or impacts as usual. This will assist in monitoring the onset of the cooler weather expected to affect the region. Those spending time outdoors next week should be prepared for a shift to cooler conditions, particularly in the evenings and early mornings.
