Scrape HTML to Display Stuff On My Site

Scrape HTML to Display Stuff On My Site

I'm new to jQuery and scripting so hopefully this is something simple.
 
I have a site with an empty <div> tag that I want to pull specific HTML from yahoo's weather page (namely the yw-forecast and yw-fivedayforecast id's) and show inside that empty div on my site.
 
Any ideas how to do this?
 
Thanks ahead of time!
