Surprise, surprise — Mother Nature has yet another bout of snowfall in store for southern Ontario, just a few days after the region was hit with a historic ice storm.\nMeteorologists at The Weather Network are tracking a system that is expected to move into the Great Lakes region over the next two days. Rain and snow (up to 4 cm) will be spread to major locations including Windsor, London and Sarnia in the west to Niagara, Hamilton and Toronto in the east. Below seasonal temperatures will also persist throughout the rest of the week, bringing chilly conditions especially in the evenings:\nVia The Weather Network\n"Precipitation will move in with a mix of rain and snow initially into southwestern Ontario Wednesday evening and largely change to snow through the overnight into the Greater Toronto Area and Niagara region as temperatures drop," reports The Weather Network. "Throughout Thursday, snow and rain showers will linger over southern and eastern Ontario with another cold, blustery and below seasonal day with temperatures running 5 to 10 degrees below normal."\nThe good news is that the upcoming snowfall will be immediately followed with spring-like conditions for the weekend. Spring may finally be just around the corner, with abundant sunshine and double digit temperatures expected on Saturday and Sunday.\nVia The Weather Network\n"By this time, seasonal will be in the upper teens, so we could be looking at a rather quick transition from cool weather to early summer weather for late May," adds Dr. Doug Gillham of The Weather Network.
