The first 16 days come from weather models — highly reliable for the first 3–5 days, gradually less so after that. Days 17 to 30 for Chestnut Street are built from climate averages over the last 60 years, so they show typical weather for those dates rather than a specific forecast.
We compare the forecast with the climate average for exactly the same calendar days, calculated from 60 years of observations. The difference shows how the coming month compares with a typical one.
These are real historical extremes recorded in Chestnut Street since 1960: the highest and lowest temperature for each calendar date, with the year it happened.
