Every ten years the National Centers for Environmental Information (NCEI) publishes new 30 year normals for the United States. The new normals for 1991-2020 are now available. Below are the new climate normals for the six primary climate sites in eastern Iowa and northwest Illinois with a comparison to the 1981-2010 normals.

Red means the 1991-2020 normals are warmer/drier than the old normals. Green indicates the 1991-2020 normals are cooler/wetter than the old normals.
