UPDATE (5:30 p.m.) CCSD has canceled Friday classes and school activities.
Class proceeded as normal Thursday in the Clark County School District after snow fell during the night in the Las Vegas Valley.
The school district notified families via social media that officials would monitor weather conditions in case anything changed, but reports indicated the roads were safe.
All after-school activities scheduled to happen after 4 p.m. have been canceled due to the potential for freezing conditions on the roads, according to a CCSD spokesman.
The after-school SafeKey programs will also close early at 4 p.m., according to spokespeople for the city of Las Vegas, Clark County and CCSD. Parents are asked to pick up children by 3:30 p.m.
Erik Papa, spokesman for Clark County, said SafeKey can't operate Thursday because school facilities are closing at 4 p.m. The county's programs are scheduled to resume as normal Friday.
Officials expect normal operations for bus transportation Thursday, though they say some delays are possible if the weather changes.
The University of Nevada, Las Vegas and the College of Southern Nevada are both open as normal Thursday as well, the schools announced.
Nevada Highway Patrol reports all freeways in the valley are open, but commuters are advised to allow for extra travel time. Troopers responded to 28 crashes between 5 a.m. and 9:30 a.m., according to an NHP spokesman. No serious injuries have been reported.
Drivers looking to use the State Route 160 mountain pass between Las Vegas and Pahrump are advised to use chains or all-wheel drive, NHP says.
Further southeast, the Arizona Department of Transportation says both directions of Interstate 40 and U.S. 93 are closed in Kingman because of snow, ice and multiple disabled vehicles.
NHP said southbound Interstate 11 is closed at mile marker 2, near Hoover Dam, to help Arizona's Department of Public Safety with the heavy snow and road conditions.
ADOT says there is no estimated time for reopening the highways.
Dozens of flights at McCarran International Airport have been canceled due to weather. The Federal Aviation Administration says some arriving flights have been delayed by an average of two hours and 19 minutes. Check with your airline if you have a flight departing or arriving Thursday.
The scenic drive and Visitor Center at Red Rock Canyon National Conservation Area are both closed Thursday, according to the Southern Nevada Conservancy.
The National Weather Service says the official snowfall for Las Vegas on Wednesday was 0.5 inches, breaking the record for the date.
