I have been a long-time user of the Weather Underground, while my wife uses some Weather Channel app or something on her phone. We frequently have disagreements about what the high temperature for the day is/was supposed to be because we use these different services.
I really like the Weather Underground, but I must confess her numbers/rain probabilities seemed to jive better with what was happening, so I did a search to see if someone had analyzed the various weather sites for consistency and accuracy. Someone did, and how.
I’ll be honest. I mostly just skimmed through the site, because I was just interested in the conclusions (at first). An important caveat is that the analysis was done for only one location, by one guy, but I have to admire the effort and the statistical analysis.
In conclusion: I’m going to see if I can find an IntelliCast app for my phone.
