-Comprehensive weather sites

                                                                                
  These sites all focus on North America, but many include data for other       
parts of the world as well.  These sites all contain a variety of weather-      
related information:  satellite images, surface and upper-air analyses and      
plots, text forecasts, and so on.                                               
                                                                                
                                        
                                            
  Weather World from the University of Illinois (WWW) and Weather Machine       
(Gopher).  Currently undergoing work;  Weather World has no up-to-date          
data, and the Weather Machine has some but not all.  Old description:           
Satellite images, surface and upper air analyses, forecast model output,        
etc.  This server also includes a very nice and comprehensive collection of     
MPEG movies based on the still images.  They are updated hourly and they        
cover various time durations of up to over two days.                            
                                                                                
                                                
                                             
  Purdue University WXP Web site.  This site includes satellite images,         
surface plots and analyses, upper air plots and analyses, soundings, radar,     
and plots of the results from various NMC forecast models.  The text on         
each page explains very clearly the meteorological usefulness and               
interpretation of the various plots.  Questions and comments to
