Checking the Weatherby rand0mmm (Acolyte)

rand0mmm has asked for the
wisdom of the Perl Monks concerning the following question:
I am an Artist, so of course I want to open different files based on the weather. ;-)
While I am learning Perl (one project a time) I have no idea how to fit my information into a whole working thing and pull off what conceptually seems like the right tool for the right job. So far I have been learning and using perl on my website server apps, (running a wiki) called by http. This is all backwards for me now.
I want to use Perl on my Mac OS X machine to create a script that periodically checks an url and then opens and runs different interactive patches I've made in one of my local applications; suffice to call them movies. My hope is the machine will perpetually check a webpage, find the weather, and open movies with the corresponding filename, every 7 minutes.
I want to make the changing weather info at page at http://www.weather.com/weather/local/12986? open "Partly Sunny.mov" when it's "Partly Sunny" on the page, or "Windy.mov" when it's "Windy", and "Thunderstorm.mov" when it's "Thunderstorms" on the page. etc.
Since I also need to distinguish between Sunny, Calm, Windy, Raining, Thunder+Lightning and also the time of day. I figure i will be making a set of different weather files for morning, day, dusk, and night. So it figures I will need some kind of MORNINGmap, DAYmap, DUSKmap, NIGHTmap, hash-array-tablething to map the time onto the weather onto the files to play.
I notice this weather page has a nice <B CLASS=obsTextA>Cloudy</B> structure surrounding my target info. I looked for more plaintext weather data and couldn't locate anything like an http: sms server.
I have explored some related ideas a bit, and there's a mac osX tool called Automator, that can hand a webpage as input to PERL. I couldn't make it do much yet, but maybe this will be useful on my path.
This seems like a big challenge to me right now, but I am hoping someone who understands PERL can show me how simple it is and put me on a clearer path.
Any suggestions are welcome. --- --just
