The first 16 days come from weather models — reliable for the first 3–5 days and progressively less so after that. Days 17 through 30 for Barlow Park, IL are built from the climate normal, the 60-year average, so they show typical weather for those dates rather than a specific forecast.
We compare the forecast against the climate normal for those exact calendar days, computed from 60 years of observations. The deviation shows how much the coming month differs from a typical one.
They are real temperature extremes recorded in Barlow Park, IL since 1960: the highest and lowest reading for each calendar date, with the year it happened.
The forecast portion refreshes every hour; the climate portion is based on long-term data and stays stable.
