PHOENIX -- Sky Harbor reached an official high of 110 degrees Thursday at around 3:30 p.m. According to the National Weather Service office in Phoenix, that temperature tied a record set back in 2002.

Thursday’s high temperature designated June 6 as the hottest day of the year so far. Friday will top that.

A ridge of high pressure building in from the northwest will allow temperatures to heat up a couple more degrees for Friday. As a result, Friday will win the designation as the hottest day of the year.

We’re forecast a high of 112 in Phoenix. Temperatures across the Valley will range from 110 to 114, prompting forecasters at the National Weather Service Office in Phoenix to issue an Excessive Heat Warning for all of southwest and south-central Arizona, including Maricopa and Pinal counties from 10 a.m. through 8 p.m. Friday.

Residents should stay indoors in an air conditioned place during the heat of the afternoon. Those who have to work outside should take frequent water breaks, and wear light-colored and loose-fitting clothing.

The elderly and young children are most susceptible to the effects of this heat, so they should be checked on periodically. Prolonged exposure to these temperatures could trigger dehydration, heat exhaustion and heat stroke.

It's an even greater concern for the Valley's homeless population.  Central Arizona Shelter Services put out extra emergency beds on Thursday night because of the high temperatures.

"The concrete heats up during the day, and it doesn't cool down," said Irene Augustine of CASS.  "When you get consecutive days of extreme temperatures, it becomes very, very dangerous."

In addition to having extra mattresses on hand, CASS is stocking up on bottled water.
On Friday, the Salvation Army plans to set up eleven hydration stations at various locations around the Valley.
Maricopa County is also under an ozone high pollution advisory Friday. Those with respiratory problems as well as children could have difficulty breathing while outside. Limit outdoor activity during this time.

Afternoon high temperatures should dip a couple degrees heading into the weekend as a cutoff low pressure system over the Pacific moves into California.
