New clues to the summer and fall

The ECMWF seasonal forecast output was released earlier today and it continues to forecast weak La Nina conditions along the equatorial Pacific from late summer into the fall. This latest June forecast output is slightly weaker with the La Nina than the May forecast output. The latest ECMWF seasonal output also predicted the following for the rest of the summer.....

--Hotter than normal conditions for the southern Prairies, northern U.S. Plains. --No areas of below-normal temperatures across all of southern Canada. --Drier than normal for eastern Ontario and Quebec. --Hottest month in the East looks to be August.

and for the upcoming fall........

--Cooler than normal for British Columbia, while much of central and eastern Canada are predicted to be warmer than normal by the model.

--Low confidence/skill with precipitation forecasts at this time.

Tropics.......

--The latest seasonal ECMWF forecast model is currently predicting a slightly higher than normal hurricane/tropical storm frequency in the Atlantic basin this summer and fall, however the model is also predicting a slightly lower than normal ACE (Accumulated cyclone energy) for the Atlantic basin, which could argue for more weaker or short-lived systems.
