Forecasting What's Next for Weather Prediction

Weather prediction has some certainties: It keeps getting better. With every passing decade, forecasters have extended the accuracy of their predictions by one day, so today's weather forecast for the end of the week is as good as a 1980's prediction of tomorrow's weather. Now, scientists are using advances in machine learning, more accurate climate models, and big data to improve the accuracy of forecasts. Peter Neilley, the director of weather forecasting science at The Weather Company, joins The Point to discuss this evolution.  Heather Goldstone hosts.
