MOST ACCURATE FORECAST: Big warm up in store for Arizona

Posted
and last updated

PHOENIX — Our early weekend storm system is pulling away from the state and with it go our rain chances. Now we begin our big warm-up.

High pressure builds back in next week, bringing temperatures neary 10-15 degrees above average.

Phoenix will reach the 90s by Tuesday and could flirt with the triple digits by the end of next week.

If we hit 100° next Thursday or Friday, it would be our first triple-digit day of the year and one of the top 5 earliest 100° days in the city's history. A high of 100° on Friday would be record-setting for that date.

On average, Phoenix sees its first 100-degree day around the beginning of May.
