Good to see this bad boy set today. Tucson will set a record for having an entire month (June) with every day at or above 100 degrees F (38C).
Will probably also set a record for the most consecutive number of days above 100 as the forecast calls for more searing heat for at least another week.
The deep red color is from high level smoke from a forest fire (Silver Fire) burning in the Gila Wilderness some 130 miles east of Tucson.
The smoke actually helped to create a thin cloud layer over our area, which kept the temperature down a bit from what was forecasted.
