This weekend brings the Formula 1 auto-racing competition to the Circuit of the Americas in Austin, TX. The race has arrived during a heat wave for the Lone Star State where highs have run about 10-15° above average through much of the region, and where widespread daily high-temperature records have been falling daily (see above). Luckily, cooler temperatures will arrive just in time for the main race. Still, temperatures will be pushing 90 by the afternoon hours.
After widespread records fell across the Lonestar State Saturday, including Austin, by Sunday clouds and cooler air from an approaching upper low bring down temperatures slightly, but humidity values will be on the rise.
The bigger cool air influence arrives at the beginning of next week with highs dropping into the mid-80s, and much more close to average. Notice those overnight lows creeping up into the 70s though? Moisture from the remnants of Hurricane Norma in the eastern Pacific Ocean will stream into Texas increasing rain chances through mid-week, which will keep overnight lows warmer and daytime highs cooler.
