How do you get Canada's historical weather system maps?
I need to get the systems map ( a weather map showing current systems) for the 25th of march 2011. The theweathernetwork.com only keeps the current one. If you don't know what I mean by weather map you can see todays here: http://www.theweathernetwork.com/index.php?product=weathermaps&pagecontent=weathermaps&maptype=sys. If you know where I can get one for the 25th I would really appreciate it. (I am in Canada, so one that shows Canada would be most relevant to me, but any would help.
thanks in advance
