What is each month like in Orland Park?
NOAA's grid estimates the normals every 5 km or so from the stations around each point, terrain included. It smooths between stations, so night lows at the heart of a large city can run warmer than the grid shows: at five big-city airports we compared, the grid's highs were within about 1°F of the station and its lows 1-6°F cooler. The nearest record's high and low are beside each month.

How much snow, how late a frost, what zone and how much sun in Orland Park?
NOAA's grid gives no snow, frost dates or records, so these come from the nearest station record, Little Red School House (7 miles N, 715 ft). NOAA publishes no snowfall normal for it; the nearest record that has one, Burbank (10 miles NE), gets 39 inches a year. The last spring frost (32°F) comes after April 19 in half of years and the first autumn frost before October 22.
The USDA's 2023 Plant Hardiness Zone Map puts Orland Park in zone 6a across its 2 ZIP code areas.

Little Red School House's page has its months, frost probabilities, records by month and recent years. NOAA's grid has monthly figures only, so there are no day-by-day month pages for Orland Park; the nearest record's month pages have them.
