How to research weather - temperature and dewpoint? (climate, days, precipitation)

[maxx233]

What tool have you found to research the historical weather for different cities in the US - specifically allowing cross reference between dew point and temperature? Ideally showing this information on a graph for a selected date range. More ideally, also allowing additional data such as precipitation to be included on the graph. Non-ideally, raw numbers are really just as well so long as they can be viewed for a range of dates.

I was using the weatherspark dashboard - which was absolutely wonderful for this, but it appears to have recently folded. I'm now at a loss for how to do this. What I'm trying to do is compare weather for various places by finding the highest dewpoint for the last couple years, then looking at what the temperature reached that day as well. And perhaps repeating the process for the number of days over x dewpoint and/or temperature, etc. The end goal is to have a realistic idea of where we might be comfortable moving to based on actual hard data that we can compare to our own personal preferences rather than subjective recommendations from others such as "it really doesn't get too bad in SomeCity."

Any ideas to explore are much appreciated. If there's a service that provides access to the raw data in some sort of downloadable or queryable format then that works as well as I could program my own front-end to view it with. Any help is appreciated!

Have you looked at the wunderground history feature? I don't know if it's quite what you are looking for, but I used it to compare temps and dew points of the various cities I considered moving to. There is also a weather sub forum on CD where the weather nerds (meant as a compliment ) might be able to offer some other suggestions for good sites.
I also found gardening maps to be useful, especially the sunset climate zone maps
