Another option is to check out
Google Maps APRS. It's an amateur radio site for a special type of "ham" radio operation (Amateur Packet Reporting System - APRS), but it displays tons of information, including both amateur radio weather station information and the CWOP weather station information. You'll find hundreds of "private" weather stations - those little blue "WX" icons - that report into that system. Clicking on icons will drill down for much more information. You'll find weather graphs (parameter versus time) for most weather stations.
The first time you go to the site, you'll probably be in Finland on the map because that's where the guy who operates it lives. Just move the map anywhere you want to. The information is primarily amateur radio stations that "beacon" information over a radio or directly into the internet. (I can send and receive this type of information directly using my radios - it doesn't "require" the internet, but the internet makes the information available worldwide - and special stations (usually the ones with a green star icon) transfer the information from the radio domain to the internet.) You'll find "home" stations as well as mobile stations (you can track them moving around - you can change how long a period of time you want to see). You'll find my home station in The Villages (WB2UTI - that's my amateur radio FCC call sign) and if you search for WB2UTI* you'll see other stations I operate - yes, I even have an APRS radio in my "golf cart" - WB2UTI-4. You'll see my car driving around as WB2UTI-9. I'm probably at the "station" with the most recent transmission (although my home station beacons regularly every 30 minutes).

I know - why in the world would I want anyone to know where I am? It's useful information for those of us who respond to emergency situations - our colleagues know where we are (it works with my portable radio or even with a phone application). We also use it to support events such as charity organization bike rides. They usually have very long (100-mile) routes that we patrol in our "beaconing" vehicles so that the nearest one of us can easily be sent to someone who needs help. Trust me, it's very useful. It's not for everyone, but for those of us who use it, it's great.
Anyway, take a look at it. If nothing else, it's probably not something you've seen before...
