HFD had 2 missing days for this month so I plugged the BDL values in for an estimate. I did the same thing for the missing day in 2014.
Anyway, when Steve ran the numbers the much lower mean for HFD compared to BDL stood out to me. Now that I know HFD was missing data it looks closer than it originally did. I forget if 2014 was the previous year where we kept bitching about the BDL temps, but historically, BDL has almost always run cooler than HFD for July.
