[AZ-Observing] Re: Great Weather Data

This summer I was looking for information about average highs and lows so I 
could make more sense out of the seasonal temperatures here in the Phoenix 
area and resorted to making this graph out of historical data I found on the 
web:

http://www.christensenastroimages.com/weather.pdf

It was interesting to me that the shape of the graph is different depending 
on whether you are in the first or second half of the year.  Also how long 
the hot summer tempertatures persist before finally giving way to cooler 
temperatures was striking to me.  Last, but not least, how flat the graph is 
at the hottest part of the year, averaging 104 for a long time for the high 
but busting up to 105 for a few days.

I don't remember where I got the data, but I know it was in a table by 
month.  Maybe it was somewhere on this website:

A number of years ago I found a web site that had the daily max and min
temperatures and then what they were the same date a year ago for
Prescott. I think this data existed for other cities also. I found this
very useful, but I can no longer find the web site. Does someone have a
link to it, or did it get incorporated into one of the sites where you
have to pay to get the data?
