COMET Case Study 030 documents a null weather event where forecasts predicted over a foot of snowfall for Eastern Colorado's Front Range on March 20, 2000, but only 3 to 5 inches were reported. This case is the first in a series of null-event studies compiled by SCIOPS. The data was last updated on March 21, 2000.
Use Cases
- Analyze the discrepancy between forecasted snowfall amounts and actual reported snow depths for the Front Range region.
- Study the temporal progression of the storm using forecast issuance times and subsequent observation times.
- Compare spatial weather effects across locations like Denver and Fort Collins mentioned in the case description.
- Use the documented null event to train models for identifying over-forecasting scenarios in winter weather predictions.
