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: http://www.weatherunderground.com/cgi-bin/findweather/getForecast?query=85014 Jon Christensen ----- Original Message ----- From: "Stan Gorodenski" <stanlep@xxxxxxxxxxxxx> To: <az-observing@xxxxxxxxxxxxx> Sent: Friday, December 28, 2007 10:31 AM Subject: [AZ-Observing] Re: Great Weather Data 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?
