100s arriving a little late this year

Posted: Updated:

Officially, Tucson has NOT reached the triple digit mark yet this year, but record highs for Tucson have been in the 100s since mid-April. 

The first average 100° day for Tucson was May 26th. 

At present it looks like Tucson could end the month without reaching that 100 degree mark. 

It will be a close call on Friday! 

Then Saturday Tucson definitely hits the 100s. 

High pressure is taking over northern Mexico. 

That high pressure is pushing out a dip of cool air that kept the temperatures mild this last week of May. 

Below is a list of the first average 100° days across Southeast Arizona. This is data compiled by the National Weather Service Office in Tucson
