Computer model of a storm forecast using data from the Goddard Earth Observing System (GEOS-5) global model. It shows predicted air temperature anomalies for the 23rd of December 2022 in North America, one of the days over which storm Elliott occurred. Air temperatures shown range from -25 degrees Celsius below average (dark blue) to 10 degrees Celsius above average (orange) with white areas representing a prediction of average temperatures. When it struck, storm Elliott was around 3200 kilometres wide, and led to more than 200 million people being put under some form of weather advisory. Record low temperatures were recorded in numerous locations.
