Strong, south to southwest winds will impact much of eastern and Atlantic Canada over the next couple of days with the potential for some isolated power outages due to falling branches.
The map below shows the expected wind gusts for Thursday/Thursday night, though we could see some isolated gusts that are even higher...
The winds will likely be strongest coming up along Lake Erie, through the Niagara region Thursday afternoon and night and then up into the Lake Ontario area by later Thursday night.
By Friday, the strongest winds will concentrate in the upper Saint Lawrence Valley thanks to Lake Ontario and as the downsloping winds accelerate off the higher terrain (Adirondacks) to the south.
The winds will also be quite strong in the Bay of Fundy region as the air gets funneled up into that area.
The map below shows the expected rainfall from this storm through Friday night.......
A significant storm will push inland between Vancouver Island and western Washington on Saturday. The storm will produce strong winds just to the south of the track and most likely over western Washington on Saturday.
In addition to the coastal rain, there will be accumulating snow in the Coastal Range and into the Canadian Rockies Saturday with some areas getting at least 25 cm.
The accumulating snow will spread into the Prairies later Saturday and Saturday night. At this point, it looks like the heaviest snow (10-15 cm or even more) will run from near Red Deer, AB to near Saskatoon, Sask. However, any shift in the track will have major implications on snowfall. More on this tomorrow.
Very warm air will gradually shift back into western Canada in early June.
