NOAA Weather Normals
National Oceanic and Atmospheric Administration

Brief Summary

Daily station normals for US cities have been added to the database.  2 new columns have been created to support this.  (NormalHighTemp and NormalLowTemp).  They have been attached to our existing US city symbols.  CD's have been processed for the time frame 1961-1990 and 1971-2000.  Normals are good for 10 years. 

The data will appear in the database as follows:

Calendar dates 1991-2000 will contain the normals from the 1961-1990 cd.
Calendar dates 2001-2010 will contain the normals from the 1971-2000 cd.

ex: NormalHighTemp of HOUSTON.TX, NormalLowTemp of CHICAGO.OHARE.IL

Update frequency

Every 10 years
