GRAND RAPIDS, Mich. (WOOD) — Every 30 years, the National Oceanic and Atmospheric Administration updates the climate standards that meteorologists use as a guide for “what’s normal” for each weather station.

This has been done for years, and is a standard practice by NOAA These 30-year climate normals are most used by broadcast and forecast meteorologists to give people an idea of how the weather on a given day compares to usual. It is not the same as long-term climate data, which can go back hundreds of years.
