Looking at Los Angeles, where we're going tomorrow, Leopard's weather widget (accuweather) predicts cloudy but sunny for friday, the yahoo app in the phone says full-on rain. What's more accurate, in your experience?
that'll teach me for not reading anything properly.
I've always found the OSX widget pretty accurate so I'd go with accuweather. Plus cross referencing my local weather with my Local BBC weather the one on OSX is far closer to that than the yahoo one.
The most accurate weather widget I have ever found (and by which I judge the accuracy of other forecasts) is the Aviation Weather widget. It is totally accurate and updated very frequently. Just enter the location of the airport nearest to your point of interest.
