The National Weather Service in Las Vegas has issued a forecast that suggests a change in the weather pattern could bring wind advisories and cooler temperatures to the area early this week. According to the NWS weather forecast, an oncoming trough is expected to incite an uptick in south or southwest winds come tomorrow, with a significant dip in temperatures by Tuesday. Moisture from Tropical Storm Ileana is predicted to influence weather conditions, potentially leading to showers and thunderstorms in eastern Mohave County tomorrow.
Steady winds of 10-15 mph are anticipated for some areas today, ahead of the approaching trough descending from the Gulf of Alaska. The forecast indicates a "modest increase in surface dewpoints" which could lead to elevated moisture levels and a slight chance of convective weather events. Winds could intensify even further by tomorrow afternoon, leading to a Lake Wind Advisory for Lake Mead and Lake Mohave. These conditions will likely carry over into Monday, potentially expanding across areas such as Death Valley into southern and central Nye County with "gusts to 35 mph," as reported by the NWS.
Temperatures, which will remain in the 90s across the desert regions through tomorrow, are poised to plummet well below normal as we enter the week. Las Vegas Valley residents may experience the season's first lows in the 50s by Tuesday. As the upper low moves through California and Nevada on Monday, it will not only ramp up the wind gusts but also bring along much cooler air that will last throughout the week.
The second system expected to trail Sunday and Monday's system could enforce another round of breezy conditions and increase the likelihood of precipitation, "from Tuesday night all the way through Thursday," according to the NWS. This follow-up system will inject another chilly blast into the Desert Southwest, ensuring the persistence of below-average temperatures into the upcoming weekend. As the city prepares for the shift in weather, Harry Reid International Airport anticipates "breezy south-southeast winds" and potential visibility complications due to smoke from wildfires in Southern California. Local authorities and spotters are on alert and encouraged to report significant weather impacts according to established protocols.
