MOST ACCURATE FORECAST: Heating up! Phoenix set to top 105 degrees for the first time this year

Posted
and last updated

PHOENIX — Temperatures are heating up as high pressure builds in.

Phoenix may top 105 degrees for the first time this year today.

Our average first 105-degree day is May 22nd, so heat this intense is not uncommon for late May even as temperatures run 10 degrees above our daily average.

Temperatures will start to drop as breezes pick up on Friday.

Here in the Valley, gusts will peak near 25 mph. Up north, gusts could top 35 mph on Friday, bringing more critical fire weather conditions to parts of the high country as conditions stay dry.

Winds will back off over Memorial Day weekend as temperatures fall into the upper 90s and low 100s across the Valley.
