Las Vegas woke up warm and clear Thursday, with Harry Reid International (KVGT) already near 82°F just after 5:30 a.m. PDT on June 25. The heat is only getting started: the forecast calls for a scorching high near 107°F this afternoon, the hottest day of the week, with very low humidity that makes the heat feel even more relentless. If you have outdoor plans, shift them to the early morning or find some dependable air conditioning for the afternoon.
Forecast Through The Weekend
According to NWS Las Vegas, afternoon highs are expected to climb to around 107°F today, with south winds gusting into the mid-20s this afternoon. A stronger system moves in Friday into Saturday, and the Fire Weather Watch has been upgraded to a Red Flag Warning from Friday morning through late Saturday evening. Widespread gusts of 35 to 45 mph are expected, with localized gusts up to 50 to 55 mph. Afternoon humidity will stay extremely low, often in the 5 to 15 percent range, raising blowing-dust concerns and making it easier for any new fire to spread fast.
Impacts And Safety Tips
Clark County has daytime cooling stations open across the valley through June 28 for anyone who needs a break from the heat; locations and hours are listed by Clark County. Tie down or bring in loose yard items before the strongest winds hit on Friday and Saturday, and hold off on any spark-producing work, such as grinding or welding, during the warning period. Be ready for sudden gusts and pockets of blowing dust that can quickly cut visibility while you are driving.
Check in on older neighbors, friends without reliable cooling, and anyone who may struggle in the heat. Keep pets in the shade with plenty of water, and if your home loses power or your cooling fails, head to one of the open cooling sites to ride out the worst of the afternoon temperatures.
