Case 2 - December 29-30, 2000
So, after a look at these particular data sources and trends, let's look at the evolution of Winter Storm Watches, Warnings and Advisories:
 
  • Important points:

    •  
  • The data shown so far would have provided nearly 12 hours of lead time in significantly adjusting the Watch/Warning/Advisory areas
  • This was the last chance to change the forecasts before the 11 PM local newscasts, which would have been enough notice to prevent the "Surprise, no snow!" when people woke up in the morning
    •  
  • Definitions:

    •  
  • Winter Storm Watch/Warning
  • VA/MD - Potential/Expected 5+" of snow in 24 hours
  • NC - Potential/Expected 4+" of snow in 24 hours
  • Winter Weather Advisory
  • VA/MD - 1-4" of snow expected
  • NC - 1-3" of snow expected
