Barrier Jet Forecasting: Eastern Foothills and High Plains of Colorado, 17-20 March 2003

Barrier Jet Forecasting: Eastern Foothills and High Plains of Colorado, 17-20 March 2003
This case exercise looks at a barrier jet event over central and eastern Colorado that took on historic significance in terms of snow amounts and variability in snow distribution. The module emphasizes the mechanisms for producing both very large accumulations and extreme small-scale variability. These mechanisms involved both dynamic and thermodynamic processes in this storm. Model and observed analyses and forecasts are considered in detail as the storm unfolds.
