Las Vegas is out of the excessive heat danger zone, but temperatures will still climb well past the 100-degree mark today, according to the National Weather Service.

The slight drop in peak afternoon temperatures — from 108 on Saturday to 104 today — will be caused by high pressure being suppressed south as an area of low pressure moves through the northern intermountain states, the weather service said.

Southwest winds will also increase this afternoon, with gusts as high as 30 mph, forecasters said.

Temperatures will begin cooling off a bit, starting on Labor Day, when the afternoon high will reach only 97 degrees, forecasters said.

Peak afternoon temperatures are expected to stay below the 100-degree mark for the rest of the week, with afternoon highs reaching 99 degrees Tuesday, 92 Wednesday, 87 Thursday, 90 Friday and 92 Saturday, forecasters said.

At 5:56 a.m. today, the temperature at McCarran International Airport was 81 degrees. The normal low for today's date is 72 degrees. The record low was 52 degrees, set in 1940.

Around the valley just before 6 a.m., temperatures were 84 degrees at North Las Vegas Airport, 74 degrees at Nellis Air Force Base and 78 degrees at Henderson Executive Airport.

Temperatures in the valley were to rise today to 90 degrees by 9 a.m., to 99 degrees by noon and reach a high of 104 degrees by 3 p.m., forecasters said. The normal high for today's date is 97 degrees and the record high was 109 degrees, set in 1977 and 1955.

Temperatures are expected to drop to 102 degrees by 6 p.m., to 93 degrees by 9 p.m. and to 85 degrees by midnight, forecasters said.

Monday's morning low will be 76 degrees and Monday's high will climb to 97 degrees, they said.
