Pam...
I do not know the addreses off-hand but a Netscape or Lycos
search will serve 'em up. NOAA has a great weather site. For students,
try GLOBE project (fantastic images/data updated daily by Goddard Space)
students world-wide contribute data...cloud cover, rainfall temp etc. but
the visuals and charts also include NOAA info. Lots of links from these
pages.
