Phoenix reached the highest temperature of the year so far on Thursday, topping out at 115 degrees, and we'll do that again Friday!

Low temperatures are setting records, too. Temperature at Phoenix Sky Harbor only fell to 92 degrees on Friday morning, setting a new record warm low temperature for the date. The previous record was 90 degrees, set in 2017.

Friday also marked the first day of the year so far with a low in the 90s. In 2023, we saw a record-setting 35 days with lows in the 90s.

The Excessive Heat Warning was extended through 8 p.m. Friday for the entire Phoenix Metro Area and surrounding communities.

Friday is another ABC15 Weather Action Day and we encourage you to take action now to prepare for this next round of extreme heat. Consider canceling or adjusting outdoor plans and make sure you're keeping an eye on your kids and elderly family members as they are more susceptible to heat-related illnesses as temperatures climb.

Stay hydrated, limit time outside between 10 a.m. and 6 p.m., wear light-colored, loose-fitting clothing, and watch for signs of heat-related illnesses like dizziness, changes in pulse, and muscle cramps.

As temperatures heat up and we get a boost in moisture over the next few days, our overnight lows won't cool much. Those warmer lows will be in record territory, either setting new record warm lows or coming within a degree or so of the records again on Saturday, and Sunday.

Heat is the number one weather-related killer and these sizzling hot temperatures can be deadly.

Last year, 2023, was the deadliest year on record for heat deaths.

Data shows 99 out of the 645 heat-related deaths happened when the heat risk was in the "major" category and 162 deaths happened on days that were in the "moderate" category.

Those are the heat risk levels that we’ll see in the Valley through the weekend and next week.

Monsoon moisture has increased across Arizona as we tap into moisture from what's left of Tropical Storm Alberto that's moving through Mexico.

That boost in moisture brought the first monsoon storms of the season to our state on Thursday, with more storms possible especially in the high country and parts of eastern Arizona through the weekend.

Winds will also pick up across our state the next few days as the remnants of Alberto pass by to our south.

A Wind Advisory remains in effect for around Globe in Gila county until 11 a.m. Friday. Gusts in these spots could peak near 40 mph.

Winds will pick up in the Valley too, with gusts as high as 30 to 35 mph on Friday.

Monsoon storms that develop could also produce strong wind gusts that lead to areas of blowing dust across central Arizona.

If you get caught in a dust storm, it's best to go indoors and remember to never drive through the dust. If you're caught on the road remember to, "Pull Aside, Stay Alive" until visibility improves.

The Valley could get stronger winds and areas of blowing dust again Friday, as storms develop to our east and southeast. While there's a slight chance for showers and thunderstorms on Friday, Valley storm chances ramp up on Saturday and Sunday.
