Lots of clouds, plus some showers at times, helped keep temperatures a little lower than expected today as highs mainly reached the low-to-mid 80s. Shower and thundershower activity this afternoon has largely focused west and southwest of the city. In general, that should be how we close the day, but do keep an eye out just in case!

Through Tonight: Isolated to scattered showers and thundershowers persist into the evening before waning. The most concentrated activity should continue to focus west and south of the city, with many other spots staying dry. Eventually the front pushes all the way through the region, delivering drier air in its wake. Low temperatures mostly reach the near 60 to mid-60 range. North winds blow around 5-10 mph with higher gusts.

Tomorrow (Thursday): This one looks quite pleasant. Humidity is down behind the front, and winds from the northwest around 5-10 mph offer some natural air conditioning. Skies are partly to mostly sunny as highs rise to the mid-80s or so.

Better off playing the lotto: The Indianapolis Colts are offering half a million dollars to anyone who can correctly predict the outdoor kickoff temperature at all 20 games in 2014-15, beginning with preseason. Matt Lanza breaks down the odds of winning in a piece for FiveThirtyEight. In short: let’s just say they won’t be handing out any money on this one. If you still want to take a chance at being the one in 28 septillion (USA Today shows which other things you have better odds of winning), please don’t let me stop you!
