PHOENIX (AZFamily) — Warmer weather is in store for Mother’s Day weekend in the Valley, with temperatures jumping 10 to 15 degrees above average.

We have issued First Alert Weather Days for Saturday and Sunday with high temps expected near 104-105. A heads-up in case you’re planning any Mother’s Day activities, because you may want to take part in outdoor events in the morning or move those activities indoors.

And high temperatures could get even warmer by next week. Right now, models are hinting at temps near 107 Monday and 106 Tuesday. These above-average temperatures are due to a ridge of high pressure building from the west.

For the weekend, a widespread Moderate Heat Risk is expected. What that means is that the weather will affect those who are sensitive to heat, especially those without cooling/hydration, and some health systems and industries.

Right now, there are no Extreme Heat Watches or Warnings in effect from the National Weather Service, but we will keep you posted.

By the end of next week, an incoming weather system could lead to slightly cooler temperatures, but temps should still stay above average.

We’re not tracking any chances for rain in the Valley for the next five to seven days.

PHOENIX – Sheriff’s officials in Maricopa County say a man has been arrested in connection with a case involving a Utah teen who was reported missing in late April.

What we know:

According to a May 5 statement from MCSO, 30-year-old Armando Sanchez-Lopez was arrested on April 29, after he was seen with the missing teen.

Investigators said the teen left Lehi City, Utah on April 24 in an unknown vehicle.

“Information provided by a family acquaintance indicated the juvenile may have been in Arizona and possibly being held against her will,” read a portion of the statement.

Dig deeper:

MCSO said it was determined that on the night of April 24, the acquaintance had provided transportation for the juvenile to a home in the area of Dysart Road and Maryland Avenue in Litchfield Park.

“The juvenile requested to be dropped off a short distance away and proceeded on foot. When the acquaintance attempted to follow, an unidentified adult male confronted him and reportedly brandished a rifle, prompting the acquaintance to leave the area,” read a portion of MCSO’s statement. “In the days following, the acquaintance received messages from the juvenile indicating she was being held against her will and was in need of assistance.”

On April 29, investigators said they received “updated information that the juvenile had returned to a residence in the area and had subsequently left on foot with an adult male toward another nearby address.” They later contacted the teen and the man, who turned out to be Sanchez-Lopez.

What’s next:

Per MCSO, Sanchez-Lopez has “five prior sexual related accusations involving several victims.” He is accused of sexual assault, sexual conduct with a minor, kidnapping, aggravated assault, custodial interference, and failure to comply with a court order.

Officials say MCSO’s Special Victims detectives are still investigating the case.
