A fairly weak clipper storm system will slide southeast tonight and Friday, producing a narrow band of accumulating snow from northern and western Alberta to extreme southern Manitoba.
In general, expect 2-8 cm of snow (less on paved surfaces) with this particular storm.
As the storm tracks farther east Friday night and into Saturday it will gain some moisture and there is the potential for slightly higher amounts in the Sudbury/North Bay region of Ontario later Saturday and into Saturday night.
Some additional snow amounts from this storm.....
Thunder Bay, Ont.....2-3 cm
Sudbury, Ont....7-12 cm (poss. mixing)
North Bay, Ont....5-10 cm (poss. mixing)
Ottawa, Ont....trace....brief wet snow over to rain
Montreal, Que....mostly rain
Quebec City.....5-10 cm Sunday
Coastal storm for the Maritimes later Friday and Friday night
A quick-moving coastal storm will spread a cold rain up into the eastern Maritimes on Friday. The track and the upper level temperatures would normally support snow on the western and northern side of the storm, but low-level temperatures will be just a bit too warm (it is April now). However, just enough cold air will wrap in as the storm center moves by and thus I expect the rain to change to wet snow across northern Nova Scotia and PEI sometime Friday night for a few hours before it ends.
