Short Range Aviation Model Forecasts for North America

Forecasts by the Aviation model (a short integration of the MRF model performed at 1200UTC each day, issued by the National Centers for Environmental Prediction (formerly the National Meteorological Center) are presented individually, or in sets of two formats: either in a set of six panels for each 12 hour interval out to 72 hours, or as a series of seven panels showing the evolution in time of a particular set of fields.

Short Range ETA Forecasts for North America

Forecasts by the ETA model (see the paper by T. L. Black in the journal Weather and Forecasting, vol 9, issued by the National Centers for Environmental Prediction (formerly the National Meteorological Center) are presented individually, or in two formats: either in a set of six panels for each 12 hour interval out to 48 hours, or as a series of five panels showing the evolution in time of a particular set of fields.

Medium Range Forecasts for North America

Forecasts issued by the National Centers for Environmental Prediction ( model documentation) are presented as individual images, or grouped together in two formats: either in a set of six panels showing all fields for each 24 hour interval from 0 (analysis) to 144 hours, or as a series of six panels showing the evolution in time of a given field.
