The Weather Service tracks lows of 36 or colder, on the assumption that it is the point when patchy frost becomes possible. Today’s the calendar date of the latest “first” 36 degree-or-cooler temperature of Fall in Indy, according to the Service. That was on October 28th in 2005. Closest so far this season? The low was 38 last Saturday morning. Same story in Muncie. The latest “36 degree day” *had* been October 26, 1967! Muncie came thisclose Tuesday morning, when the low was 37. Lafayette fell all the way to 32 last Saturday morning, October 22. The latest 36-degree-day” there is November 7, 1940, so that particular record is safe. Bloomington also got down to 36 last Saturday, well before their latest date of November 5, 1971. The average temperature for the month (through Thursday) is 61.0 degrees. If it stayed just that mild we would end up as the eleventh warmest October on record in Indy. But it will get a boost from highs today and Sunday in the 60s, and in the 70s Saturday! Expect the warmest Halloween since 2008, when it was 71. It was 73 in 2003. The record high is 82, from 1950. Trick or Treat temperatures should remain in the 60s during the evening hours.
