A few more days of unseasonably warm heat on the forecast, with Tucson poised to experience its first 100-degree day of 2017 today or tomorrow.

After that, big changes will begin, with windy conditions this weekend and a slight chance of showers and thunderstorms that runs through next week. Along with the potential storm activity comes a cooling off period, with high temperatures in the 70s expected to run through Friday.

High: 99

Low: 69
