*Temperatures are expressed in degrees Fahrenheit and precipitation values are expressed in units of inches. 

** Normals and departures from normal are based on the current 30 year climatological normal period (1981-2010). Monthly rankings are based on the entire period of record, which is much longer than the normals period.  For Huntsville, precipitation data date back to 1894, while temperature data date back to 1907.  Periods continaining missing daily data were not counted in the rankings. Annual and seasonal temperatures are computed from the average of daily temperatures. 

*** Note: The average for 100+ temperatures is based on the 1981-2010 climatological period...in which there were 57 occurrences. Although...100+ temps do not occur every year.

**** Note: The wind and pressure sensors failed on a few occasions for brief periods during the year.  The values listed are the maximum or minimum values recorded, and may not necessarily reflect the actual max or min values that occurred during the year.

These data are preliminary and have not undergone final quality control by the National Climatic Data Center (NCDC). Therefore, these data are subject to revision. Final and certified data can be accessed at the NCDC - http://www.ncdc.noaa.gov.
