As I write this in the 6pm hour Sunday the Indy temp is 17 with a wind chill of 6. That’s warmer than it’s going to be again until Tuesday afternoon. Chills tonight should drop to around 10 below, and could go as low as 20 below early Tuesday morning.
The computer guidance is all over the place. Take your pick…10, or 2. (25 or 6 to 4?) Or, you could go with the short-term output below, which puts the negative numbers all the way down into Indy. (My picks are up top. Bottom line: COLD.)
