There are many web sites that allow you to display their icons and weather data using HTML code snippets and remote images. Such displays often include the logo from those sites as well as a link back to those sites. Here are a few such sites:

1. Weather Channel
2. Weather Reports
3. Weather Underground

But that kind of reciprocal agreement is not necessary; you don't have to show someone else's logo, and you don't have to display the weather in their format. The National Weather Service provides weather data on the internet for free. The National Weather Service is funded by American taxpayers and therefore the data they produce is already paid for.

This overall solution happens in two steps. First, you have to download the data on a regular basis (i.e. hourly). Second, you need some kind of script to read that data and display it on a web page.

In addition, you could also setup scripts that do things like e-mail the current temperature to your cell phone at 8:00am every day. Etc.

Downloading:

I'm providing the two scripts that I use for reference purposes here. You won't be able to just download them and run them, but with a little tweaking, you should be able to make them work the way you want. One is a Linux shell script, the other is Perl. There are two types of weather data to download:

• current conditions
  
  You can download your current weather conditions in XML format by using a URL like this:
  
  http://weather.gov/data/current_obs/KGRB.xml
  
  To do this, you first need to find out your ICAO Location Indicator. Then use it as I did in the URL above. The indicator for Green Bay, WI is "KGRB". You can look yours up here:
  
  http://www.weather.gov/tg/siteloc.shtml
  
  Here's the Linux shell script that I use to do the download. The comments in the script should be self-explanatory.
  
  getweather.sh
  
  
• forecast
  
  I haven't yet found a good reliable formatted forecast, so I just download the mobile version of the NWS page and parse that. For example, here's Green Bay's weather forecast:
  
  http://mobile.weather.gov/port_mp_ns.php?select=1&warnzone=WIZ039
  
  The quickest way to find the URL for your local forecast is to start here:
  
  http://mobile.srh.weather.gov/
  
  Just enter your zip code, click "Go", then click the link for your 7-day forecast.
  
  Here's a Perl script that I use to do the download. The comments in the script should be self-explanatory.
  
  getweatherforcast.pl
  

Using The Data:

If you've setup the above two scripts properly, you'll now have two data files that you can use in many ways. Such solutions are beyond the scope of this page, but you can probably think of ways to use it.

One idea is to write a CGI script that reads the data and displays it on a web page (you might display the data on various web pages using different formats). Another might be to read the data each morning and send a message to your cell phone with the current weather conditions. The idea here is that you now have the raw data, it's always current, now do something with it.
