TUCSON, Ariz. (13 News) – We’ll outdo ourselves today with a high of 99 expected, breaking a daily record, with a shot to break the record for the latest triple-digit day in Tucson’s recorded history. We’ll have more chances to break that record as temps stay in the mid-high 90s through Friday, heating up to right around 100 both Saturday & Sunday. However, there’s a light at the end of the tunnel as temps plummet by next week to possibly the 70s by Tuesday.
