    Computer Model Forecast Update for the Summer

    May 16, 2011; 11:54 AM ET

    The ECMWF has released their updated computer model seasonal forecast for the summer. I will issue my personal summer forecast for Canada within the next 10 days.

    ECMWF model temperature departure forecast.

    ECMWF model precipitation departure forecast.

    Also, the new ECMWF update still indicates near neutral El Nino Southern Oscillation conditions through the summer.

    The ECMWF is also predicting above normal tropical cyclone activity for the Atlantic Basin this year, especially in the Caribbean.

    The ECMWF continues to forecast a very hot and dry summer from the U.S. Rockies to the southern and central Plains of the U.S.
