Love this page. Your doing a great job.
ridiculous
These predictions are a mix of best guess and common sense, neither of which necessarily predicts anything at all when it comes to weather. Warm wind from the south, cool from the north? Gee, who'd have thought? How about this: warm this summer, followed by a cold winter period.
Pfft
Extreme Cold
Will there be any extreme cold(arctic blasts) across the Maritimes this year? has it ever happened before?
A new fan
I've been monitoring your site for the last several months and am very impressed by your accuracy. I have already asked santa for a copy for Christmas and shown him where to he can purchase a copy. After reading the reviews I'm anxious to read the new 2020 edition.

This September and October we had a lot more preciptation as was predicated. November has been Much colder than the last 10 years . The temperature has reached -10 degrees C. three times this month . We have so much more snow this year than the last three years .
Not sure what the normal is but we have much more wind this year in Sept. Oct. and November.
