The Weather Blog, The Baltimore Sun's first online Web log, is 5 years old today. Since Sept. 10, 2004, we have posted about 2,500 entries and 2,200 reader comments, and now average 14,500 page views a week. Snowstorms and hurricanes can boost weekly traffic past 100,000. But items on comets, meteors, bright planets and passing satellites often draw the most reader comment. Thanks to all for your support.
