Current ETA Ingredient Maps

The ingredients maps present some diagnostics for the ingredients for winter season precipitation in a 4-panel plot. These maps are generated for 800:850mb, 700:750mb, and 600:650mb and on a cross-section. They help a forecaster to identify the role each ingredient plays in the model-generated precipitation forecast and can aid in identifying areas of potentially convective snowfall.

A full description of the Ingredient maps, including access to the gempak code to generate these plots, is presented on the Ingredients Analysis Tool Page.

Recent changes to the operational ingredients maps are now listed on a separate What's New? page
