Phoenix Heat Wave: Tropical Humidity Grips Southwest
9 Sep
Summary
- Phoenix faces extreme heat warnings with dew points in the mid-70s.
- Temperatures are expected to reach 105 to 109 degrees in Phoenix.
- Humidity levels will make the heat index feel hotter than Miami.
High pressure is causing temperatures to soar across Phoenix and the Southwest, with heat alerts active throughout the work week. Phoenix is anticipating highs between 105 to 109 degrees, while southwestern Arizona and southern California could see temperatures near 110 degrees. Overnight lows will remain in the 80s due to persistent cloud cover.
Extreme heat warnings are issued for large parts of Arizona and southern California. Despite a summer with many days already exceeding 110 degrees, the current concern is the tropical-like humidity. Dew points are reaching the mid-70s, significantly increasing the heat index and making the weather feel more oppressive than usual for this time of year.
As September progresses, normal high temperatures are decreasing. However, the combination of intense heat and high humidity during the first two weeks of September poses a greater risk. While rain chances are low in Phoenix this week, scattered thunderstorms may develop in eastern Arizona later in the week, with better odds by Friday evening.
