Hard-freeze warning for tonight in Las Vegas Valley

Updated January 1, 2019 - 10:12 pm

A cold snap has come to the Las Vegas Valley to kick off 2019.

The National Weather Service on Tuesday predicted that the overnight low will be the valley’s coldest weather in three years, with a forecast 28 degrees at McCarran International Airport.

The weather service issued a hard freeze warning from 10 p.m. Tuesday through 8 a.m., Wednesday, a stark difference from 2017 — the warmest year in Las Vegas’ recorded history, and the first time the airport never reached 32 degrees or below in a calendar year.

The National Weather Service forecasts lows in the upper 20s for Las Vegas, but some outlying areas such as Mountain’s Edge, Summerlin, Henderson and Nellis Air Force Base could see lows in the upper teens to lower 20s. Southern Clark County, the Pahrump Valley and southern Mohave County in Arizona could see lows in the mid-teens to mid-20s.

A hard-freeze warning means temperatures will be well below freezing for many hours. Weather service meteorologist Alex Boothe said valley residents should wrap their exposed pipes, run water through them periodically or allow a slow drip, and bring pets and potted plants inside.

Tuesday should be breezy with temperatures in the afternoon reaching 45 degrees, Boothe said.

“But at least it will be sunny out,” he added.

Winds are expected to die down overnight, allowing temperatures to drop to a chilly 28 degrees in the valley, Boothe said.

Wednesday should bring calm conditions and sunny skies, with temperatures in the afternoon climbing to 48 degrees, Boothe said. Temperatures will dip to 30 degrees overnight.

Beginning Thursday, temperatures will inch back toward the normal for this time of year and winds will be light. The weather service expects temperatures Thursday to be will reach 54 degrees in the afternoon, Friday will see a high temperature about 58 and Saturday’s forecast high is 57. Overnight lows will be 35, 40, and 42 respectively.

A blanket of clouds will move into the valley Saturday ahead of another weather system that could bring rain, Boothe said.
