13 First Alert Weather Forecast | Wednesday, December 20, 2023

LAS VEGAS — Las Vegas climbs to the mid 60s this afternoon (10° above-average) with a mostly sunny sky and only a 10% chance of a stray shower. Lows drop to the upper 40s the next few nights. Expect mostly cloudy conditions with a stray shower chance Thursday (20%) before a round of more widespread rain develops Friday morning through Friday night and lasts into Saturday morning. The chance of measurable rain in Las Vegas is about 70%, with amounts around 0.20" causing slippery streets. Highs Friday are limited to 60° due to thick clouds and occasional showers. Amounts near 0.50" are likely in Laughlin and the rest of southern Clark County as a weather system passes from Southern California to Arizona. Showers linger Saturday morning but should clear in the afternoon as highs reach the low 60s. Freezing levels will be high this week, above 8,000 feet during the daytime, so snow amounts in the Spring Mountains look light; Mt. Charleston and Lee Canyon may pick up a couple inches of snow, primarily Thursday, Friday, and Saturday. Mostly sunny and cold weather returns to Las Vegas for Christmas Eve Day and Christmas Day; highs reach the mid 50s in Las Vegas. We'll drop near 40° Saturday night, and the mid 30s Sunday night (perfect as Santa makes his rounds) as well as Monday night. Highs remain in the 50s through next week.
