Weather Data Aggregation for Bike Touring

[dummey]

I'm attempting to do the Trans Am Bike Race this coming June and, with this wonderful weather we are having in the Midwest, have scripting something to help me get a better understanding of the weather I will be facing and where along the route I can start shipping off extra gear.

This is what I have for the Trans Am Route: https://docs.google.com/spreadsheet/ccc?key=0Ajb2R5ATcYg1dE5HQWNYb3lNTzd2ekR6ZFhnNDJ4elE&usp=sharing

Which is great, but I am sitting here thinking that there must be something out there already that can not only show this data, but also do fancy things like overlay the data onto a map. Maybe even show direction of winds during that time of year also.

So, anybody know of such a site/tool?

Be very careful of relying on that kind of historical data.  All it tells you is what has typically happened in the past, it says nothing about what can (and will)  happen to you. Remember the cliché:  Climate is what you expect, weather is what you get. 

As soon as you send your cold weather clothes home, Murphy says the temperature will drop by 20°.    As an example, in the late '90's I was on a week-long organized camping bike ride in Ohio in mid-June and it dropped into the upper 30's two nights in a row.  The riders who assumed it would always be warm that time of year spent a very uncomfortable couple of nights.

Ship your extra gear back home if you want to but I'd want to know where I could replace it if I had made a foolish mistake.
Some gear is impractical or may become unnecessary as your trip progresses. Maybe not.
On Cycle Oregon a tour participant is likely to experience rain, snow and 90F in a week. ONe day we went from 80F on the eastern side of the Blue Mtns, climbed to the pass in light snow, descended in wicked cold rain and ended on the western side wet and cold but in 60F and set up camp in the sun.

For the TransAm in the summer, I recommend taking gear to sleep and ride from 30 to 100 F. I also recommend keeping it all with you the whole way. I've seen too many people get very cold on a cold night after they had already sent their sleeping bag home.

It might occasionally get outside the 30 to 100 range, but you'll just suck it up for those times.

All the analysis in the world won't prepare you any better than this simple advice.

I agree with John. Solid advice. Toss in an emergency bivy bag and you are set for an even wider temp range.

This is a tool I use on a regular basis here is an example but it is highly customizable. http://www.wunderground.com/wundermap/?lat=35.03744888&lon=-85.30740356&zoom=8&pin=Chattanooga%2c%20TN some times you have to load it twice to get it to work.
