How to read this

Each line is a separate forecast run. The brightest one is the latest, older runs fade out. When all lines agree, the model is confident. When they fan out for a given day, the forecast is still unsettled — plan accordingly. Pay attention to direction of drift: if successive runs keep easing a blow back, the weather is trending milder than earlier runs suggested.
