Serious Question for the Web Savvy?

I hope you all don’t mind. A lot of you all seem to be very very computer literate. I was wondering if it was possible to... or if it can even be done…????
Can a group of web pages be screen shot and saved for posterity?
I want to be able to press a button or, even better, have it automatically do it.
Here is the reason. My company is in the construction field. It can happen that the job is running behind and the client is unhappy with progress. We schedule based on predicted weather and intuition. Sometimes the weather guys just miss it all together but sometimes it is right on the money. What I don’t understand is why the collective has not made an archive of the predictions of the weather. The actuals are good for historical value but in our case the predictions are what we have to base the work schedule.
So if it was possible to have a macro type program that would go to the web sites we use, and snap a screen shot of the predictions and save them to a file for later viewing it would be very important data when the questions come up.
Does anyone know if such a thing exists?
