PHOENIX — The Valley is finally getting a taste of fall as cool air settles in across Arizona.
Morning lows in the Valley will dip into the upper 50s to mid-60s Tuesday morning. It hasn't been this cool since early June!
Our cooler weather will be fairly short-lived as another ridge of high pressure sets up across the area later this week.
Valley highs will reach the upper 80s on Tuesday, then mid 90s again by Wednesday.
Highs will climb back into the upper 90s and low 100s by Thursday and Friday. The average last triple-digit day is October 5th, so it's possible that these will be the last few 100-degree days of the year.
Monsoon 2023 officially ended over the weekend and it's 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.
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.
