‘Eee by gum! I sure hope someone got back Olive aboot flying lessons for her wee grandson.

The weather up here has been fair t’ middlin’

Good Job

They tell us at the top that these predictions are not location-specific, but only show trends based on recorded cycles for the various regions. Don't expect them to tell you what the weather is for your private function on any given day. But must say, for my region, the trends for October this year so far are spot-on.
