Temperatures near record prompt heat warning

Summer heat is a daily occurrence, but oppressive temperatures the next couple of days will fall just short of record-setting territory.

The National Weather Service issued an excessive heat warning today for the Las Vegas area. The mercury should reach about 112 degrees in the Valley, with temperatures as high as 117 in the Lake Mead area.

The heat warning will be in effect from 11 a.m. to 8 p.m. today and Wednesday in areas below 4,000 feet in elevation.

Forecasters blamed the heat on a high-pressure system settling over the region. A high of 112 would be one degree shy of a record set in 1989, when the high reached 113 degrees on this date at McCarran International Airport.

Wednesday will be nearly a carbon copy of today with a high temperature of 111 degrees. That would be two degrees short of a record set back in 1943.

The average high at McCarran on today's date is 104, according to weather service records. Temperatures have reached the triple digits each day since June 13.

After two more days of temperatures in the middle and upper 100s on Thursday and Friday, a change is in store for the weekend.

Forecasters said monsoon moisture is expected along and southeast of Interstate 15 this weekend, bringing with it a slight chance of rain and storms. Severe weather and flash flooding will be possible, the weather service said in a statement this morning.

The airport hasn't recorded rain since May 24, when one-tenth of an inch fell.

The highest temperature ever recorded at McCarran in the month of July is 117 degrees.
