SCOTTSDALE, Ariz. (KSAZ) - What a difference a day makes. On Thursday, the high temperature was 109°F (~42.78°C). On Friday, the forecast high was just 93°F (~33.89°C), representing a 16°F swing in temperatures.
Those cooler temperatures are expected to stick around until Saturday, which is disappointing some runners who were planning to take part in an extreme challenge.
Eager competitors in the Scottsdale Beat The Heat picking up their race materials Friday afternoon at the Talking Stick Resort in Scottsdale, and they cannot wait to test themselves against the brutal Arizona summer sun.
But what if it's not brutal, but positively balmy?
Preparations are underway at Westworld, where the racers will start and finish. The race will feature 5km and 10km races. Runners start near 3:00 p.m. on Saturday, which means they're usually out there pounding the pavement, during some of the hottest hours of the day.
Instead they may be dodging raindrops.
