These are the forecasts of 500 mb heights (m) valid at 12Z 1/25/00 compared to the Eta 500 mb height analysis valid at that time for 4 different Eta cycles. The plots are displayed in the order in which that model cycle was run. The verifying analysis from the Eta is shown in orange, and the particular forecast is in purple. The forecast from 00Z on the 24th shows major problems everywhere. The 12Z and 18Z forecasts both struggled mightily with the northern stream over west-central Canada and the southern stream coming into the west coast.
