PHOENIX — Temperatures are soaring well above average and into record territory this week!
Phoenix will top out at 106 degrees on Wednesday, putting us nearly 10 degrees above the average high for this time of year.
We'll also warm to within striking distance of the record high. The record stands at 107 degrees set in 2009.
It's also going to be a dry week, which means we won't add any more rain to the official monsoon bucket.
Monsoon 2023 is going down as the driest on record with only 0.15 inches of rain at Phoenix Sky Harbor. The previous record was set back in 1924 when we measured 0.35 inches of rain that season.
High pressure is responsible for the warm-up as it also pulls in dry air across the region.
By the end of the week and this weekend, a large trough pushes into the west and the Great Basin region bringing stronger winds and cooler air into Arizona.
Wind gusts will peak near 35 mph here in the Valley, and near 50 mph across the high country on Saturday.
We won't see any rain, but temperatures will fall into the mid-90s on Saturday and then down into the upper 80s by Sunday, to start the new month.
Phoenix hit 110 degrees or hotter 55 days this year, breaking the old record of 53 days set in 2020.
Phoenix also reached a high of 115 degrees or hotter 22 days this year. That too is a new all-time record, topping the previous one of 14 days set in 2020.
When it comes to overnight temperatures, Phoenix had 35 days this year with lows in the 90s. The previous record was 28 days set in 2020.
September 10th this year also marked the latest day in any year with a low in the 90s. Previously the record was September 7, 2019.
