Las Vegas is expected to have its coldest morning in 378 days on Thursday, as temperatures drop below the freezing mark and snap an all-time record for the longest stretch without a freeze.
McCarran is projected for an overnight low of 31 degrees, and outlying areas of the valley could see pre-dawn temperatures in the upper 20s, according to the National Weather Service.
“This will bring an end to the longest period that we’ve ever gone without a freeze at McCarran (International Airport),” said Clay Morgan, a meteorologist for the weather service in Las Vegas.
“Presuming it actually does freeze, it’s also going to be the latest first freeze on record for a season,” he said.
The last time the temperature dropped below freezing at McCarran was Dec. 7, 2011, when the low reached 31 degrees.
Morgan recommended making sure that pets have a warm place to go, that plants sensitive to cold are brought indoors and that water pipes are protected.
Thursday’s high is expected to reach 48 degrees. Things will start to warm up Friday, the first official day of winter, which should be mostly sunny, with a low of 36 degrees and an afternoon high of 53.
For the weekend, clouds will increase a little, with high temperatures in the mid 50s and lows in the lower 40s.
