Currently running +1.9 at ORD this month. Will whittle that down in the coming days but not sure it will get all the way to 0.
You can see some Nino influences on the pattern, but some non-Nino looks as well. Could get a "non-Nino" period in July where it gets warmer but this just doesn't look like a summer that will want to put out huge heat. Not surprising I guess.
