What is each month like in Noblesville?
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 Noblesville?

The last spring frost (32°F) comes after April 21 in half of years and the first autumn frost before October 21.
