Freezing rain and falling snow helped round out the month of March, with the first snow pellets spotted in the Toronto area Friday evening.

A weather system that has already made its way through Texas and Kansas is heading to southern Ontario and is expected to bring between two and four centimetres of wet snow with it, said CTV weatherman Tom Brown.

By 6 p.m. Friday there were already reports of snow pellets and sleet in Toronto.

In areas north of the city, there were reports of snow accumulating on the ground, with a CTV viewer in Port Carling reporting nearly eight centimeters of white stuff on the ground.

By 8:30 p.m., OPP issued a statement warning drivers of slow and icy conditions on Highway 401 in Oxford County.

After reaching temperatures well above 20 C and setting a series of weather records this month, Toronto will continue to see the other side of the coin over the weekend, according to Environment Canada.

Friday began with morning temperatures below freezing and a daytime high of just 4 C.

Environment Canada issued a weather statement for the Greater Toronto Area Friday, predicting the arrival of freezing rain by the afternoon.

"The snow and freezing rain will likely impact rush hour traffic this evening," Environment Canada said in a statement. "Temperatures will reach a few degrees above freezing this afternoon but quickly drop to near or below freezing once the snow begins. Drivers should exercise caution as untreated roads may become slippery and snow-covered and visibilities may be reduced in bursts of heavier snow."

According to the statement, snow and ice pellets are expected to fall along the eastern part of Lake Erie, north through Lake Huron and reaching western Lake Ontario by the evening.

The weather agency says there is still some uncertainty about which areas will see freezing rain and snow, but have included Toronto, Hamilton, Barrie and the regions of York and Halton in their alert.

There is a chance of flurries Saturday morning before temperatures rise to 8 C. More rain is predicted for Sunday.
