The new ECMWF model seasonal forecast was just released yesterday to our in-house system. The long-range model now goes out to the November/December/January period.
1. The model is predicting moderate El Nino conditions to develop late this summer and fall and persist into the winter, but not strengthening.
2. The model continues to show slightly below-normal tropical activity for the Atlantic Basin through the fall.
3. The model appears to favor a tendency toward a positive NAO late fall into early winter. Here is a great link that explains the NAO phases and impacts.
