I don't think weather forecasting has gotten much better in the past forty years.
Perhaps with the prediction and accuracy of tornadoes? But run-of-the-mill temperature, precipitation chance, humidity, wind - not much seems to have changed and that's not saying a whole lot.
Still loved it when I was in Los Angeles several years back and the local news channels were all advertising that they had the most powerful Doppler radar in the area. Can't find the commercial, but here's LA ABC7's Mega Doppler 7000 HD page... eyes rolling. (It's stated in the title of the page.)
Oh, and by the way - Los Angeles receives on average 14 inches of rain a year, with 92% of that coming during the rainy season (November to April). Big whoop. .
