6:20 P.M. UPDATE JAN. 26: Lee Canyon says it received 27 inches of snow in the last 72 hours, bringing its base to 61-inches. READ MORE
6 A.M. UPDATE JAN. 26: Snow is flying early this morning across much of Las Vegas.
There's new snow on the ground in places like Aliante, Centennial Hills, Lone Mountain, and Summerlin. It's even started to stick in the southwest corner of Las Vegas near Rhodes Ranch and parts of Mountain's Edge at 3:30 a.m.
Most of the snow will wind down by 7 a.m. but the Winter Weather Advisory continues in Las Vegas until 10 a.m.
Travel will remain difficult across the higher terrain around Las Vegas this morning, including the Spring Mountains, Mountain Pass in California, I-40 near Kingman in Arizona, and I-15 in Utah.
Look for partly to mostly cloudy conditions the rest of the day, with highs in the mid-40s and 5-15 mph breezes.
The next system delivers a slight rain chance on Thursday with a better opportunity Thursday night through Friday night.
6 P.M. UPDATE JAN. 25: Light valley rain and heavy mountain snow continue to fall with cold and cloudy conditions expected through dinner time.
By 10 p.m., more widespread precipitation will push in from west to east.
The rain to snow transition should start around midnight with widespread snow expected by 3 a.m.
Since rain precedes the snow, the ground will be wet, but snow accumulation is still expected by sunrise tomorrow, complicating the morning commute.
Up to 3" possible on the west side and south valley, with a dusting up to an inch for the Strip, East Las Vegas, Sunrise Manor, and up through Nellis Air Force Base.
The radar should settle down by 8 a.m. with the Winter Weather Advisory and Winter Storm Warning both expiring at 10 a.m. The remainder of your Tuesday features cold and cloudy conditions with highs capped in the mid-40s, more than 10° below average.
2 P.M. UPDATE JAN. 25: After a wet and cold start to Monday morning, another push of spotty showers is in the forecast this evening with more widespread precipitation expected into Tuesday morning as snow levels drop low enough to include most of the Las Vegas valley as lows fall to the low to mid-30s.
Rain totals will range from 0.25 to 0.50 inches in Las Vegas with up to an inch of snow possible for most of the city by Tuesday morning.
For elevations near 3,000 feet like Anthem, Summerlin, Mountains Edge and parts of Centennial Hills 1 to 3 inches of snow could accumulate before the system exits Tuesday.
A dusting is possible for lower-elevated communities like east Las Vegas, Sunrise Manor, and at Nellis Air Force Base.
With surfaces starting wet from the evening rain, there is a chance accumulations come in lower by Tuesday morning but road conditions will still be slick to start the day regardless of how much snow actually sticks in Las Vegas.
9 A.M. UPDATE JAN. 25: The Winter Weather Advisory continues for Las Vegas and other parts of Clark County until 10 a.m. Tuesday.
A Winter Storm Warning remains in place for the Spring Mountains and the Sheep Range during that time.
Rain showers will overspread Las Vegas between 9 a.m and 3 p.m., and rain totals will ranger from 0.2 to 0.5 inches that will cause slippery roads. Additional spotty rain showers are in the forecast Monday night and early Tuesday.
Another round of rain is expected to cross Southern Nevada on Thursday and Friday, to the tune of 0.1 to 0.3 inches of rain.
Snow may overtake the rain in Summerlin, parts of Centennial Hills, and parts of Mountain's Edge while the heavier rain showers fall during the daytime.
In other parts of Las Vegas around 3,000 feet of elevation like Anthem, the better chance of snow showers will arrive after dark.
A chilly rain (to the tune of 0.2" to 0.5") will make streets slippery today, tonight, and tomorrow morning. The threat of some accumulating snow is also a concern. I can't rule snow out in Anthem & Summerlin during the daytime. Near The Strip, it's more likely after dark. pic.twitter.com/iZXhAKGDmE— Justin Bruce (@just1nbruce) January 25, 2021
Any of these areas could see up to 2 inches of snow accumulate before the system departs on Tuesday. Surface temperatures will also drop near freezing Monday night, so slick travel is possible late and into Tuesday morning.
Near the Strip and across the rest of the Las Vegas valley, snow showers are possible through early Tuesday and it's possible that up to 1 inch could accumulate mainly on grassy surfaces. Surface temperatures could dip to the mid-30s.
Heavier snow totals are expected in the higher terrain away from Las Vegas:
2" to 8" in Red Rock Canyon
11" to 16" in Mt. Charleston
12" to 18" in Lee Canyon
7" to 10" in Mountain Springs
It goes without saying that the high elevation areas will pick up the most snow today, tonight, and early tomorrow. Travel in these areas is discouraged then. pic.twitter.com/01GjK0YyTJ— Justin Bruce (@just1nbruce) January 25, 2021
The National Weather Service has issued a winter weather advisory for Clark County including parts of the Las Vegas valley.
NWS says snow is a possibility for the west side of the valley as a winter storm sweeps through the area early Monday through Tuesday at 10 a.m.
A dusting of snow is likely to fall at elevations above 2,000 feet and they are calling for 8-16 inches of snow in the mountains in Southern Nevada and northwest Arizona.
