Temperatures are expected to rise following the coldest overnight temperatures in three years in the Las Vegas Valley.
It dipped to 28 degrees overnight Tuesday at McCarran International Airport, the National Weather Service’s official recording site. A hard-freeze warning issued at 10 p.m. Tuesday ended at 8 a.m. Wednesday, and overnight temperatures on Wednesday should only reach about 33.
Tuesday’s overnight temperature — the coldest since Jan. 1, 2016 — was a stark difference from 2017, the warmest year in Las Vegas’ recorded history, and the first time the airport never reached 32 or below in a calendar year, according to the weather service.
Wednesday’s high temperature peaked at 48 degrees, and highs are expected to climb back into the 50s the rest of the week.
Thursday should reach 52, paired with a low of 36, while Friday is expected to hit 56 during the day and 39 overnight.
A storm system is expected to enter the valley Saturday afternoon, though the weather service is not expecting it to bring cooler temperatures. Saturday’s high and low are forecast at 56 and 41, respectively. Sunday will follow with a high of 52 and low of 39.
The storm system will bring scattered showers Saturday evening, but meteorologist Alex Boothe said the “main show should be on Sunday.”
Sunday’s 30 percent chance for showers won’t generate “a whole lot of rain,” Boothe said, but rather a cloudy day with showers across Southern Nevada.
Overall rainfall amounts should be “pretty marginal,” he said.
