The Numerical Weather Prediction Revolution and a Warm Memorial Day Weekend Forecast

What is the key technology behind weather prediction?   How can computer "models" predict the weather days in advance?  You will learn about this in my podcast today.   And I will provide the Memorial Day weekend forecast, which portends lots of sun and warming temperatures.  Look forward to highs reaching 80F in western Washington early next week, and over 100F in portions of eastern Washington.
