The Stanford study proposes that meteorologists try to account for these gaps in knowledge when making predictions. Mostly cloudy skies with a few snow showers late. Weather forecasting is a technology used to predict the weather. And temperature trends are more accurate than day-to-day precipitation trends. Winds NE at 5 to 10 mph.
