Heat continues building in Las Vegas region

The high temperature in Las Vegas is expected to move up 2 to 3 degrees Wednesday as high pressure holds over the region, the National Weather Service says.

The forecast high is 104 after Las Vegas reached 101 on Tuesday. Skies will be mostly sunny with southwest winds 5 to 7 mph switching from the southeast in the afternoon.

Lows dropped only to the mid-80s early Wednesday, hinting at a very warm day ahead.

The low Wednesday night will be near 80.

Thursday will be the hottest day of the week with a projected high of 107.

As a low-pressure system moves in from the Pacific Northwest, Friday’s high will drop to 102. Las Vegas will fall to a high of 90 on Saturday, followed by 88 on Sunday.

“The system is becoming more potent, so the winds will pick up, and Monday the temperature will bottom out at 86,” weather service meteorologist Jen Varian said.

Clark County will be opening daytime cooling stations from Wednesday and Thursday as temperatures are set to climb into the triple digits.
