MOST ACCURATE FORECAST: Heating up across Arizona this week

Valley could reach triple-digit temps this week
Posted
and last updated

PHOENIX — Winds are dying down across Arizona tonight and they'll stay relatively light throughout the day tomorrow.

As high pressure builds in, temperatures will continue to heat up.

Phoenix will be back in the triple digits by Wednesday, putting us several degrees above normal for this time of year.

Phoenix could top 105 degrees for the first time this year on Thursday. Our average first 105-degree day is May 22nd, so heat this intense is not uncommon for late May.

Temperatures may drop a little heading into Memorial Day weekend, but it looks like it won't be enough to get us out of the triple digits.
