Light snowfall is expected Tuesday from the first system, with heavier snow set to develop overnight into Wednesday with the second system. Behind these pair of clipper systems will be another round of lake-effect snow targeting communities southeast of Lake Huron and Georgian Bay lat week.

Two clipper systems to bring another healthy swath of snow into Wednesday
The week began with a midwinter-like chill, bringing the coldest daytime highs in more than nine months to places like Toronto and Ottawa. Temperatures remain well below seasonal for most areas.
A clipper from the Prairies will bring a quick burst of snow Tuesday across central and southern Ontario. A general 2-5 cm is expected throughout the day, with blustery winds causing some blowing snow into the evening.
A second clipper arrives Tuesday night, carrying Pacific moisture, which will increase snowfall amounts and introduce slightly milder air.
