Record-Setting Race Day Ahead

We hit 90 Saturday which was the hottest since 92 back on September 13th. Sunday will be even hotter as we meet or beat records!

For the record: the hottest Indy 500 was on May 31, 1937 when it hit 92. The hottest May 27th was in 1911 when it hit 94. The hottest day in the entire month of May was May 28, 1911 when it hit 96. We could contend for each of these! I’m forecasting a high of 94. If we reach 94, that will be the first time in 78 years we’ve made it to 94 or hotter during the month of May!

A Heat Advisory continues overnight and Sunday until 8pm. The combination of heat plus humidity will likely mean heat index values in the mid 90s to 100 degrees. I’m forecasting the highest heat index for Indy to top out at 99! Drink plenty of water, wear light-colored clothing, seek shade, and take care!

Sunday is also another Knozone Action Day. Elevated ozone levels will put our Air Quality Index into the Code Orange – Unhealthy for Sensitive Groups – category, which means if you’re elderly or very young or have any respiratory problems, it may be more difficult to breathe. Staying indoors will help. And for the rest of us, waiting to mow or refuel will help keep ozone levels from growing higher.

If you’re heading to the race, here’s your Hour-By-Hour Race Day Forecast. Morning temps in the 70s will pave the way for a green flag at noon with temps in the upper 80s heading to a high of 94. It will feel much hotter than that!

We’ll stay dry until Memorial Day Monday, but as a cold front approaches late Monday, we may see strong to severe storms develop, especially northwest of Indy where a slight risk of severe storms is possible. Storms will continue into Tuesday morning, the cooler air filters in. We’ve only had officially 0.1″ of rain since May 10th, so we can use the moisture!

Behind the cold front, temperatures cool-down in a big way as you can see in your 7-Day Forecast. By Friday, we might have unseasonably cool highs in the 60s!

Finally, our Hoosier Pic Saturday at 6. While most areas haven’t seen rain in days, parts of Hamilton County got storms Friday, including Arcadia where Curtis Browning shot these storm clouds through the sunshine. Submit your pic – just post it on WTHR’s Facebook Page:

Enjoy the rest of your holiday weekend!
