Significant snow is likely in the D.C. area Wednesday night into Thursday, but as the storm is still 36 hours away, it’s still tricky to predict exact amounts.

At the extremes the National Weather Service is predicting as little as three inches (bottom 10th percentile) and up to nearly 20 inches (top 10th percentile).
