*****IMPORTANT NOTICE*****
Beginning with the July 2004 monthly summary, the average temperature 
will be calculated by averaging the daily averages. Up to this point, 
the average was calculated by first determining the average maximum 
and minimum temperatures for the month and then averaging those two values. 
This change coincides with a change in the calculation of the daily average 
temperature. The daily average temperature is now being calculated as an 
average of the 24 hourly values. This change was made to conform to WMO 
regulations. Up to this point, the daily average was being calculated by 
averaging the maximum and minimum temperatures for the day.
In order to have a consistent data set, we will eventually be recalculating 
all the daily and monthly averages as far back as our records will allow. 
This will take some time. A notification will be sent out upon completion 
of this task along with details on how to access the amended data set.
