PHOENIX (AZFamily) — Historic early-season heat will bring a prolonged stretch of dangerously high temperatures to the Valley.
Phoenix could experience its first 100+ degree day of the year as early as Wednesday, with 105 degrees or higher possible Thursday through Saturday.
For perspective:
- The earliest 100-degree day on record in Phoenix occurred on March 26, 1988.
- The earliest 105-degree day occurred on April 20, 1989.
So far today, the high at Sky Harbor has reached 91 degrees, just shy of the record 92 degrees. Overnight lows will remain mild, falling into the mid-60s.
Monday’s high is expected to reach around 91 degrees, which will stay below the record of 99 degrees.
Because of the extreme early-season heat, Tuesday through Sunday are First Alert Weather Days. Anyone spending time outdoors should take precautions:
- Drink plenty of water
- Take frequent breaks in the shade
- Avoid prolonged exposure during peak heat
