The biggest weather story from this year’s Race won’t be rain, it will be the heat. Highs are probably going to hit the mid 80s, just like last year. THAT followed a couple of cooler years.
RECENT RACE DAY HIGHS:
85 in 2015
79 in 2014
68 in 2013
91 in 2012
88 in 2011
89 in 2010
86 in 2009
There was a toasty trend from 2009-2012, finishing with a tie for the second warmest Race Day ever. The high of 91 in 2012 tied with 1953 and 1919.
The coolest stretch of years ended about a decade ago. SIX of the top 12 coolest Race Days occurred between 1992 and 2003, including back-to-back Race Days in the 60s in 2000/2001.
The last time a race was completely postponed was 1997. That’s unlikely this year. However. Still a slight chance of showers and storms Saturday through Monday, especially in the heat of the afternoon.
Western Indiana has a marginal risk of severe weather Wednesday and the tip of northern Indiana has a marginal risk Thursday. Here are the SPC charts for today and tomorrow and the next day.
This week’s weather drama stars a big trough that has burrowed into the middle atmosphere out west. Here it is Wednesday.
By the weekend that trough tries to move east, but encounters a big ridge of high pressure that should tilt it backward a bit. In Indiana that should decrease the storm chance and increase the temps.
