Shower Chances In The Indy 500 Forecast

By · May 25, 2013 at 7:26 pm

Scattered showers make for a less than ideal Indianapolis 500 forecast.  Confidence is high on rain to be on Live Doppler 13 Radar during the race… but there is a great deal of uncertainty on whether showers will move over the track.  That’s a question that can’t be answered until analyzing radar, surface data Sunday morning.

Healthy cloud cover over Central Indiana will keep temperatures pleasantly cool near 50 when the gates open at 5:30am, and afternoon highs in the mid 60s.  Below is a comparison of two Future Trak 13 computer model runs to show you what we use for “guidance” in putting a forecast together.  Both indicate the highest chances of rain will be just southwest of the I-65 corridor, but the exact location is very subject to change.  It’s good to remember that 25-50 miles could make a major difference in the amount of rain the track sees Sunday.

Based on latest data sets I’ve opted to put the Indy metro area in a 50% rain chance… odds that could significantly drop (or rise) based on the morning radar set-up.

 It will look and feel more like summer after Monday, when highs soar into the mid/upper 80s.  Unfortunately the muggy meter climbs and A/Cs will get a workout in the days ahead.  Don’t forget Eyewitness Sunrise at The Track starts at 5am Sean Ash
