Brace yourselves, Las Vegas! After a tumultuous weekend that saw downpours and flash flood warnings across parts of Southern Nevada, the start of the new week brings a deceptively calm and sizzling Monday. The desert sun reigns supreme today, promising clear skies and blistering temperatures, but don't let this serene facade fool you – the forecast suggests a potential return to dramatic monsoon action later in the week.
Today, residents and visitors alike will bask under brilliant sunshine with the mercury soaring to a scorching high near 108 degrees Fahrenheit.
However, this intense heat isn't just a casual inconvenience; a heat advisory is firmly in effect for significant portions of Southern Nevada, including the entire Las Vegas Valley, lasting until 8 p.m. this evening. As night falls, expect partly cloudy skies with temperatures dropping to a still-warm low around 88 degrees.
As we roll into Tuesday, the weather picture begins to shift.
While the day will start hot and mostly clear, there's a slight 10 percent chance of afternoon thunderstorms making an appearance. The heat remains unrelenting, with highs once again hovering around 109 degrees. It's a subtle hint of what's to come, urging everyone to stay hydrated and vigilant.
Midweek, the chances for rain and storms become more pronounced.
Both Wednesday and Thursday carry a 20 percent probability of afternoon and evening thunderstorms. While the odds aren't overwhelmingly high, these desert storms can be intense and unpredictable, bringing localized heavy downpours, strong winds, and the ever-present risk of flash flooding. Temperatures will continue to climb to dizzying highs near 108 degrees on both days, keeping the region in a sweltering grip.
Looking ahead to the end of the work week and into the weekend, the forecast offers a return to more typical Las Vegas summer conditions.
Friday and Saturday are expected to be sunny, with highs settling into the lower 100s – a slight, but welcome, reprieve from the earlier week's extremes. Sunday follows suit with more sunshine and temperatures remaining in a similar range.
So, as you step out today, enjoy the dazzling sunshine, but remember to stay cool, drink plenty of water, and keep an eye on weather updates.
Las Vegas is known for its sunshine, but this week, it's also set to remind us of the desert's powerful and unpredictable monsoon season.
