I thought you told me last summer that two months is too short a period
to establish any trend in terms of GW. At the time I was commenting
upon the unusually wet and cold summer that eastern Ontario and
probably the areas in the US just to our south, was having. By the way
our July this year was extremely cold although August has returned to
more usual temperatures with highs in the range of 25 to 31.
