I’ve been to Yahoo! weather, weather.com and a few other weather sites, and they all seem to only show the weather forecasts for the next five days or so (which I guess is all that’s relevant). But where would I go if I were curious about what the temperature was 3 days ago? Anyone know?
Thanks,
Meanie
Go to NOAA’s weather service page:
http://www.crh.noaa.gov/forecasts/DCZ001.php?warncounty=DCC001&city=Washington
Enter your zip code and pull up the current conditions. At the lower right you’ll see a link for “past weather” which, when I do it goes back two days.
Actually it looks like you can go back quite a few years. Numbers galore!
Aww, the past weather link works for your zip code, but not for mine. 
I tried a bunch of other local zips, and nothing works. What does NOAA have against SoCal?
Try www.wunderground.com First get your local forecast, then, under the heading “History & Almanac”, you’ll find “Detailed History”, which will hopefully give you what you’re looking for.
That’s odd.
Try this:
http://www.wrh.noaa.gov/Monterey/
On the left hand side under “climate” click on local data.
I set (1) to daily climate report, (2) to San Francisco, and (3) to archived date (the date you want).
It was 55° on March 2nd.
I figured it out. Even though some zip codes don’t have a “past weather” link, they should have a “local climatology” link. Follow that and you should be able to find a past weather link that will allow you to dig up historical data.
Phew. Off to bed.
Quit livin in the past
Yay! Okay, I finally have the weather for earlier this week. Thanks all. 
Actually, weather.com has past weather. When I enter my zip code, and look at the 10-day forecast, there’s a little box above it that says “Yesterday’s Weather” and if takes me to…surprise…yesterday’s weather. That page has a pulldown box that lets me go back to any day in the last week.
Here’s the page, not for my ZIP, but for one that’s pretty famous:
Oh crap, why didn’t I see that? Ah, well. I found what I was looking for eventually. Again, thanks all.
