Finding Weather History Fast

A pretty common query for us through our Ask the Meteorologist and AskGreg forums through the years has been how much rain fell on such and such date, or what were the highs and lows for the two-week period following Labor Day? Jenn Deters was just asking us about precipitation over a range of dates from the 25th to 30th of September last year, for example.
A quick way to get that info, especially if the numbers from the Raleigh-Durham airport will suit your purposes, is to click the Almanac link on our main weather page, then look for the date selector next to "Get Historical Data:" This will take you to an archive operated by The Weather Underground, where they have compiled a massive database of hourly and daily observations from hundreds of weather stations. Our link takes you to RDU for a single day by default, but once you get there you can change date, view the data by day, week, or month, and change to other observation sites as well.
For Jenn's purposes, the site quickly yielded the amount of rain from Sept. 25-30, 2008 at RDU as 1.48 inches, most of which fell on the 25th, 26th and 27th.
