Forecasting technology has come a long way since KNKX weather expert Cliff Mass first got his start in the field. He often marvels at how precisely most events can be predicted, using powerful computers that run ensembles of modeling programs that meteorologists compare before they decide what to tell the public. The aim is helping people prepare, especially for potentially dangerous weather. But in the Northwest, snow – especially the kind that hit parts of Western Washington this week – is notoriously difficult to forecast. Mass agrees, this past week was a case study in that challenge. |
