While early, the average first 100-day is May 26, it's no record breaker.

The earliest it has hit 100 was April 19, 1989. Last year, Tucson didn't see its first 100-day of the year until June 2.

The heat will give way over the weekend to much cooler highs. By Monday, the highs will be in the mid-70s with overnight lows in the 50s as a storm moves through the area. A chance of rain will pop up in the forecast by Sunday, increasing to 25 percent by Tuesday.
