Is there a weather app that shows me the weather right now relative to the weather at the same time yesterday?

I don't know about you guys but I always evaluate weather in relative terms("it's cooler than yesterday morning") and yet most apps just throw the temperature at you...which could be wildly deceiving depending on wind etc.

It's not an app (or at least, it isn't a standalone feature of an app), but if you search on wolfram alpha, it usually provides a handy graph for the past. I'm always wondering the same thing as well.

eg http://www.wolframalpha.com/input/?i=weather+san+francisco

and hit "more" when the "Weather history & forecast" section shows up. I don't know how permanent this URL is, but here's the result I get from that:

I would love to see a better interface on that data as a standalone app.

I've tried a lot of weather apps, and my favorite, by far, is eWeatherHD. It does just what you're asking - with a last 24 hour trace of temp and barometric pressure. It will also show you the next 12 hours of temp, what temp it feels like, chance precip, UV index, and other things.

Not affiliated in any way, but really appreciate all the details in this app, and was annoyed at all the app purchases I'd made that only showed a portion of what I wanted to know.

I also like the sunrise/set, moonrise/set, moon phase info. I only miss tide info, but am not at the beach that often anyway.

If you use iPhone/iPad, Thermo (http://thermo.me) does exactly that for temperature. Temperature right now and temperature 24 hours ago.
