With the Autumn Equinox a little over a week away, it looking like the beginning of the Fall season will be very Fall like, cool and damp. A significant trough will dig in to the eastern half of the continent mid next week, bringing cool and dampish weather for the following week or two.
Here is the mean temp anomoly for the week starting next Friday courtesy of Weatherbell.
Thursday afternoon update: Remarkable agreement in the 6-10 day upper level predictions. Note the trough (U shaped blue) in Central to Eastern N. America.
