Long-Range Model Forecast Update

April 1, 2014; 8:33 AM ET

This is my latest interpretation of the ECMWF and CFSv2 weekly long-range forecast output for Canada and the U.S.

Each panel shows the expected pattern highlights for that given week. There is more model disagreement than usual with the pattern for the middle and end of April which leads to higher uncertainty.


Great Lakes ice slowly breaking up.

The image below shows the view of the eastern Great Lakes from satellite on March 21 on the left and from March 30 on the right.

You can clearly see a loss of ice on the western end of Lake Erie and many more large cracks on Lake Huron.

As of yesterday, the total percent of the Great Lakes that is covered with ice was down to 67.4%.
