LAS VEGAS (KTNV) — UPDATE FEB. 21: After a sunny and warm Friday, lows drop to the 40s Friday evening as clouds increase ahead of Saturday morning.
Scattered rain chances arrive as early as 7 a.m. when a system swings through the southwest delivering occasional showers in the morning with widespread rain in the afternoon and evening before tapering off Saturday night.
LATEST: 13 First Alert Weather
Rain totals are expected to be near .25 inches in isolated spots around the valley with temperatures in the upper 50s under mostly cloudy skies.
After a fairly dry start to 2020, a storm system will swing across the Southwest on Saturday and deliver widespread showers.
So far this year, McCarran Airport has only totaled 0.07 inches of rain, well below the average of 1.03 inches we'd expect through the date. Saturday's storm could chip away at the deficit with up to one quarter of an inch of rain across the Las Vegas Valley.
Computer model projections have backed away from the idea of heavy rainfall in the valley, and clouds in the morning may only deliver spotty showers the first half of Saturday. Scattered rain will likely turn streets damp in the afternoon, capping temperatures in the upper 50s under a mainly cloudy sky. Showers will continue in the evening before tapering Saturday night.
A Winter Weather Advisory is in place from 8:00 a.m. to 8:00 p.m. on Saturday for the Spring Mountains and the Sheep Range. Snow levels will be around 6,500 feet, so Mt. Charleston expects accumulating snow with this storm to the tune of 4" to 8". Locations above 8,500 feet (like Lee Canyon) may see up to 12" of snow. This will make travel slick and difficult throughout Kyle Canyon and Lee Canyon until roads can be cleared Saturday night and Sunday morning.
Weather conditions in Las Vegas will recover on Sunday, with a mostly sunny sky and highs back in the upper 60s.
Sunny skies and mild temperatures today and tomorrow but BIG changes work in Saturday with our first significant rainfall of the year! Weather will be a factor for many of the events in the valley this weekend... keep it tuned to @KTNV for the latest. pic.twitter.com/WuolhTpJ9h
