Temperatures are warm over the Southwestern states, and it looks likely that daily records will be broken once again over many areas on Monday. Readings well in excess of 110° F will be common, with a few spots seeing temperatures topping the 120° F mark, threatening all-time record highs!
Sunday was the first day a potential stretch of 7-10 days worth of highs exceeding 110° F for many cities in the Southwest, including Phoenix, Arizona. Monday’s projected high of 119° F in Phoenix would shatter the old record of 115° F and puts them in range of the highest temperature ever recorded at the official airport sensor there, 122° F in June of 1990. Even if they were held to 120° F it would still be in the top three highest days ever. The hot pattern will remain stagnant beyond Monday even if temperatures edge down a bit, and it could be the better part of two weeks before temperatures fall closer to normal values.

- Phoenix, AZ: 119 (115)
- Yuma, AZ: 117 (116)
