The western United States is experiencing a blast of scorching temperatures this week, with several regions shattering high temperature records for June. Death Valley, California, the hottest place on Earth, reached a staggering 122°F (50°C) on Thursday, tying its record for the date. Las Vegas, Nevada, wasn't far behind, reaching 111°F (43°C) for the first time this year, also tying the earliest date it has ever seen a temperature that high.
The heatwave isn't limited to the deserts. California's Central Valley, known for its agricultural production, has seen temperatures soar into the triple digits, with Bakersfield reaching 108°F (42°C).
Experts warn that this early season heatwave is a sign of things to come. The National Oceanic and Atmospheric Administration (NOAA) predicted an above-average temperature season for most of the country in a three-month outlook published in mid-May. Coupled with ongoing drought conditions in many parts of the West, the heatwave raises concerns about wildfires and water scarcity.
The scorching temperatures have already caused disruptions. Several schools in California have implemented early dismissals to protect students from the heat. Phoenix, Arizona, has opened cooling centers to provide relief to those without air conditioning.
While some areas bake, others shiver. The Pacific Northwest, which typically experiences mild weather well into June, is facing cooler than average temperatures. Seattle, Washington, for instance, has seen highs only in the mid-60s (around 18°C) this week, a stark contrast to the scorching temperatures plaguing southern and central parts of the state.
The unusual weather pattern is being attributed to a high-pressure system parked over the Great Basin. This system is causing sinking air, which warms as it compresses, over the Southwest, while cooler air masses hover over the Pacific Northwest.
Meteorologists forecast that the heatwave will ease slightly over the weekend but will likely return with a vengeance in the coming weeks. Residents are advised to stay hydrated, avoid strenuous activity during the hottest part of the day, and never leave children or pets unattended in vehicles.
