A strong, southerly wind flow ahead of a storm and a trailing cold front will buffet eastern and Atlantic Canada between Thursday and Friday.
The strongest winds for southern Ontario will occur Thursday night, then shift into Quebec early Friday with gusts over 70 km/h, especially just downwind of the Great Lakes.
The two GFS model forecast maps below show expected wind gusts in knots at 2 meters above the ground for Thursday evening and Thursday night.
The model does show an area of higher wind (50 knots+) over the western end of Lake Erie and into the Niagara region just after midnight Thursday night, which may be a bit overdone, but you get the picture.
There will also be a second surge of strong winds Friday afternoon and Friday night over Atlantic Canada with gusts over 80 km/h over some land areas.
The two GFS model images show potential wind gusts in knots at the 2-meter level above ground for Friday afternoon and evening. Clearly the strongest winds will be out over the open water and also funneling up through the Bay of Fundy.
----------- Western snow potential this weekend
Also, I will continue to monitor the progress of a potential winter storm for the Canadian Rockies and into the western Prairies this weekend. Computer models have shifted a little more south with the track of this small, but potent storm which could bring the accumulating snow down into Calgary and over into Saskatoon.

Plenty of uncertainty with the weather pattern later in September.
Hot, dry conditions to prevail across BC into next week while rounds of cooler and showery weather spread from the eastern Prairies to Quebec.
