Las Vegas is bracing for a sizzling heatwave with temperatures expected to climb into the triple digits this weekend. According to the National Weather Service, an intense high-pressure system is causing temps to surge, leading to an Extreme Heat Warning for southeastern California, southern Nevada, and northwestern Arizona.
"Temperatures will peak on Sunday at 8 to 12 degrees above seasonal normals, with a forecast temperature of 108 for Las Vegas," the National Weather Service states. They caution that this escalation brings a "Major" HeatRisk particularly to valley locations, where the presence of desert amplifies the sweltering conditions. With Father’s Day celebrations in sight, the public is urged to steer clear of the outdoors during peak heat hours, stay hydrated and lather on sunscreen to mitigate health risks.
The weather is not only hot but windy. The same report highlights "breezy-to-gusty southwesterly winds each afternoon through the forecast period," as stated by the National Weather Service. This combination amplifies concerns for potential fires and residents and tourists alike are reminded to exercise caution, especially when engaging in activities that could ignite a spark in these dry, windy conditions.
Toward the beginning of next week, Las Vegas can expect some relief. A shortwave is predicted to flow through, per the National Weather Service, potentially "increase gusty winds on Monday" but also leading to a drop in temperatures "4 to 6 degrees through Tuesday." However, don't get too comfortable—the mercury is set to rise again with the ridge reasserting itself, nudging temperatures up through the remainder of the work week.
For pilots, the weather poses its own challenges. The National Weather Service aviation forecast advises, "Gusty south-southwesterly winds remain the primary aviation concern." Gusts reaching up to 25 knots are expected, which can be disruptive for flight operations, so travelers should be prepared for possible delays and adjustments.
As always, the National Weather Service encourages local spotters to report significant weather occurrences or impacts, ensuring the community's safety and helping meteorologists track and respond more efficiently to climatic conditions.
