Need help with table update

I am in the process of re-doing my web site and would like to automatically refresh and incorporate a specific weather table from the NWS web site (Current Conditions) for my area. National Weather Service I am not by any means a HTML master I know just enough to get through with FrontPage 2002, Notepad and some VERY basic HTML and alot of cutting and pasting. How would I be able make my website (using CSS template) go refresh every 50 minutes or so to the NWS weather page and update just the current weather conditions information within that table on the NWS website and then input it automatically onto my website?

I have searched this site ( for hours) and the web for the last couple of days and can not find anything to help (probably asking the wrong type of question)

If someone knows how to do this with and wouldn't mind showing me the code whether it is HTML or whatever that will work within Frontpage 2002 I would appreciate it

Thaniks in advance!!!
