Las Vegas is starting Monday under clear skies and dangerously dry heat, with temperatures already around 84 degrees before sunrise. By afternoon, the mercury is expected to climb to 114 degrees, putting another brutal day on the calendar for the valley.
An Extreme Heat Warning remains in effect through 8 p.m. Wednesday as the region faces dangerous conditions and little overnight relief, according to the National Weather Service in Las Vegas. Forecasters say heat-related illnesses will increase significantly, urging residents to stay hydrated, use air conditioning and avoid prolonged time outdoors.
Triple-Digit Heat Sticks Around
Tuesday is expected to reach 113 degrees, followed by highs near 112 Wednesday and Thursday. Friday and Saturday could again hit 113 degrees before Sunday brings only a modest dip to around 111.
The heat will also push Las Vegas into near-record territory. The National Weather Service says forecast highs through Thursday are within a few degrees of daily records, including a 116-degree mark set for August 3 and a 114-degree record for August 4.
Afternoon Winds Add Another Hazard
Southwest winds will increase through the afternoon Monday, reaching 17 mph with gusts as high as 26 mph. The breezier conditions should ease after sunset, but they can make outdoor heat exposure feel more punishing and may create difficult conditions for unsecured items.
Little Overnight Relief
Monday night's low is expected to stay near 88 degrees under mostly clear skies. Overnight lows should remain close to 88 or 90 degrees through Saturday, meaning homes and buildings may not cool down much between hot afternoons.
Monsoon Moisture May Return Late Week
The valley's day-to-day forecast remains overwhelmingly sunny, with rain chances near zero through Tuesday and only a few percentage points later in the week. The weather service's latest discussion says monsoon moisture could begin returning Thursday, bringing a greater chance of thunderstorms first over northwest Arizona and potentially into parts of southern and eastern Nevada by the weekend.
Heat Safety Remains The Priority
Residents should schedule strenuous outdoor activity for early morning or evening, take frequent breaks in shade or air conditioning and check on relatives and neighbors. Never leave children or pets in a parked vehicle, where temperatures can become lethal within minutes; anyone showing signs of heat stroke should be moved to a cool place and treated as a 911 emergency.
