Partly sunny skies with temperatures climbing up into the 60s are in store today through the weekend for the Las Vegas Valley.

But big changes in the weather are coming as a series of wet storms begins passing through the valley starting Sunday night, according to the National Weather Service.

The weather service said that a change in the jet stream will bring four to five different storm systems across the valley next week.

All the lower elevations are expected to see rain next week, although some of the systems moving through will bring more rain than others, forecasters said. Rainfall amounts could be as high as 3 inches in some areas, or a significant portion of their yearly rainfall, the weather service said.

The higher elevations will likely see several feet of total snow accumulation by the end of next week, especially areas above 8,000 feet, forecasters said.

Road conditions could be hazardous next week for areas that get heavy snow, the rains could make roads slippery and create flooding situations, forecasters said.

Temperatures were starting out today at 43 degrees at 5:56 a.m. at McCarran International Airport. The normal low at McCarran for today’s date is 36 degrees and the record low is 20 degrees, set in 1962 and 1949.

Around the valley just after 6 a.m., temperatures were 44 degrees at North Las Vegas Airport, 37 degrees at Henderson Executive Airport and 43 degrees at Nellis Air Force Base.

Temperatures were to climb today to 50 degrees by 9 a.m., to 63 degrees by noon and reach a high of 65 degrees at 1 p.m. The normal high for today’s date is 57 degrees and the record high is 73 degrees, set in 1945.

If you’re heading out tonight, you’ll find the temperature falling to 58 degrees by 6 p.m., 51 degrees by 9 p.m. and 48 degrees by midnight, forecasters said.

Saturday’s morning low will be 43 degrees and Saturday’s high will reach 62 degrees, forecasters said.
