Las Vegas is trading its late-October warmth for clouds, cooler air and a real chance of rain just in time for the holiday weekend. The National Weather Service forecast issued Tuesday evening puts the best odds of showers on Halloween night, Saturday, Oct. 31, with a first round of possible showers and thunderstorms on Friday, Oct. 30, Nevada Day.
Key Takeaways
- Friday (Nevada Day): about a 30% chance of showers early, then a chance of showers and thunderstorms. High near 75.
- Saturday (Halloween): showers possible after 11 a.m. (about 40%), then rain showers likely Saturday night (about 60%). High near 72, low around 60.
- Sunday, Nov. 1: about a 50% chance of showers before 4 p.m., high near 70, clearing at night.
- Monday: sunny and cooler, high near 69.
- Clocks fall back one hour at 2 a.m. Sunday, Nov. 1, when daylight saving time ends.
Warm midweek first
Before the change, the valley stays mild and mostly sunny. The NWS calls for a high near 78 on Wednesday and near 77 on Thursday, with lows around 60. Clouds start building Thursday night, and the forecast shows a 30% chance of showers after 5 a.m. Friday as moisture moves into Southern Nevada. FOX5 meteorologist Kyndell Kim noted skies will turn increasingly cloudy Thursday ahead of a weather system arriving over the weekend.
Halloween night is the wettest window
The highest rain chance of the stretch, about 60%, falls on Saturday night, right when trick-or-treaters and Strip costume crowds are out. Daytime Saturday carries a chance of showers after 11 a.m. Forecasters say the exact timing and rain totals are still uncertain, so the numbers could shift as the system gets closer.
What it means for locals and visitors
If you have outdoor Halloween plans, have a backup or a rain layer ready, and plan trick-or-treating earlier in the evening if you can. Wet roads after a dry spell get slick fast, so slow down and leave extra space, especially on the 15 and the 95 and around the resort corridor. Visitors heading to pool parties or outdoor shows should check with the venue for weather updates. And don’t forget to set clocks back an hour before bed Saturday night.
