ERA5 images from Fort Collins 12" snowstorms, 1979-present

The links below each indicate a 12" snowstorm, defined as one or more consecutive days of measurable snowfall, at the Fort Collins weather station since 1979. In each directory are some basic maps from the ERA5 (ECMWF reanalysis) for these cases. The maps begin 4 days prior to the start of the snowstorm, and continue for four days after that, with maps at 0000 and 1200 UTC. Select a case and check it out!
