PHOENIX — The weather is looking perfect in Phoenix as our Diamondbacks host and play in the World Series.

The roof will likely be open Wednesday night as temperatures are set to fall into the 70s by the evening.

Breezes will stick around through the morning with Valley wind gusts peaking near 25 mph.

We'll see passing clouds at times this week, but our forecast will stay dry.

As high pressure builds in, temperatures will gradually warm up throughout the week.

Daytime highs will reach the low 80s today and Wednesday, mid 80s Thursday and Friday and upper 80s over the weekend.

Overnight lows will cool into the 50s across the Valley each day.

Thankfully, we are now done with the triple digits this year. Saturday, October 21st marked our last 100-degree of the year. That's the fourth latest ever recorded.

Phoenix reached 100 degrees or more on 133 days this year. That's the third most on record. The average number is 111 days and the all-time record is 145 days, set back in 2020.
