Looking for totals not averages.  Ideally it would allow look up by zip code.
The best place would be to contact the National Weather Service for the area you are studying.  They should have data on all weather patterns collected from weather stations all around the country.  Some weather stations have only local data.  \nYou could also check the weather almanac for the specific year you would like to research.  You can usually find precip totals for every year that records have been kept.
Sure! Start with the templates available right inside your word processor, check the packaging from your labels. There may be a website to download from or even a mini-CD. Generic or custom sizes can be entered into websites such as avery, mead, daytimers, franklinplanners, etc., etc.
