Las Vegas woke up Tuesday, April 21, 2026, to clear skies, mild mid 60s and a pretty pleasant start. By this afternoon, though, the main headline will not be the sunshine, it will be the gusty south southwest winds expected to roar across the valley as temperatures climb into the mid 80s. Drivers, travelers and anyone with a backyard full of unsecured patio gear should plan ahead for a windy ride from afternoon into late evening.
Afternoon Winds Pick Up
The National Weather Service has issued a Wind Advisory for much of the southern Great Basin and Mojave Desert from 2 p.m. to 11 p.m. Tuesday, April 21, 2026, calling for southwest winds generally 20 to 30 mph with gusts up to 45 mph. A High Wind Warning is also in effect for parts of Esmeralda and central Nye counties and Death Valley, where gusts could top 60 mph. The full advisory and forecast maps are available from the National Weather Service Las Vegas. Forecasters expect the strongest gusts from mid afternoon through late evening, with winds gradually easing overnight.
What To Expect On The Road And Outdoors
On the roads, gusty crosswinds will make things tricky for trailers, RVs and other high profile vehicles on I 15, U.S. 95 and rural highways, and blowing dust could briefly knock down visibility in open desert stretches. At Harry Reid International, flyers should be ready for some bumps on takeoff and landing and might want to pad connection times a bit. For more about how this week’s pattern set up and earlier details on the incoming blast of wind, see how Vegas sunshine set the stage, and make sure any loose outdoor furniture or decor is tied down until the advisory expires.
When Winds Lessen
Overnight into Wednesday, winds should ease and shift to a lighter west southwest breeze, with daytime highs dropping back into the mid 70s by midday Wednesday. The rest of the workweek looks quieter, although another weather system could bring a return of breezy conditions over the weekend, so it is worth checking the forecast before locking in outdoor plans or projects. If you spot downed limbs, power issues or other hazards, report them to local authorities and follow instructions from official emergency channels.
