Update on the Long Range

April 23, 2014; 11:05 AM ET

This is my latest forecast model interpretation of the weekly weather patterns going into May......

The model has trended cooler over the eastern half of Canada for May, but there also seems to be a higher uncertainty than usual with a lack of strong upper-level features showing up across the Northern Hemisphere during May.

I would expect this model to continue to lean more toward above-normal temperatures from Alaska and down the Pacific coast through at least early summer as sea surface temperatures in the northeast Pacific will likely remain well above normal.

A blocking-type pattern will develop next week and this may lead to a several-day period of wet and chilly weather from southern Ontario through southern Quebec and into the Great Lakes and Northeast U.S.
