COMET_CASE_030: COMET Case Study 030:Null Event: Eastern Colorado Snowstorm


This case is the first in a series of null-event cases and presents a developing winter storm in the Desert Southwest and its effect on Eastern Colorado's weather, on 20 March, 2000. Forecasts of over a foot of snowfall by late evening on Monday the 20th of March were issued as early as the afternoon of Sunday the 19th of March, from Denver to Fort Collins. By 10 p.m. Monday, snow reports from most areas along the Front Range were only 3 to 5 inches.


This case is an example of a Colorado Front Range snowstorm that was forecast to be much stronger than what actually occurred. It allows study of the conditions necessary to produce heavy snow in Eastern Colorado, and how the models mis-represented the conditions in this case.
