Las Vegas is waking Saturday to clear skies and temperatures near 72 degrees, but the valley is headed for a sharp heat climb: 97 today, 100 Sunday and up to 108 by Tuesday. A few monsoon thunderstorms could interrupt the weekend before the forecast turns sunny, dry and seriously hot.
Saturday Storms Could Arrive After 2 P.M.
The National Weather Service says scattered showers and thunderstorms are possible after 2 p.m. Saturday, with a 30% chance of precipitation. The best odds are over higher terrain, but any storm that moves into the valley could bring lightning, a quick heavy downpour, sudden gusts and reduced visibility.
Saturday should otherwise be sunny, with east winds of 2 to 6 mph and a high near 97. Storm chances should fade before 11 p.m., leaving a partly cloudy night with a low around 81.
Sunday Starts A Week Of Triple-Digit Heat
Sunday is expected to be sunny and dry, with a high near 100 and an overnight low around 84. That is a noticeable turn from the wetter monsoon pattern Hoodline covered in July, as moisture retreats and a longer hot spell takes over.
Monday reaches 105, then Tuesday through Thursday are forecast to top out near 108, with Friday close behind at 107. Overnight lows will remain in the mid-to-upper 80s through the workweek, offering limited relief after sunset.
Rain Fades As Heat Risk Rises
After Saturday's storm chance, rain probabilities fall to nearly zero Sunday through Wednesday, then tick up slightly Thursday and Friday for a few late-day showers or thunderstorms. Winds remain generally light, although forecast speeds could reach 14 mph Tuesday through Friday.
Moderate HeatRisk is expected to develop in parts of the region by midweek. Residents should move strenuous outdoor activity to the early morning or evening, drink water regularly, and check on people and pets who are more vulnerable to extreme heat.
