Cooler temperatures and lingering showers are expected across the region Thursday, with lake-effect precipitation developing near Lake Huron, according to CTV News meteorologist Julie Atchison. The day will start overcast, with a chance of showers and possible mixed precipitation in parts of midwestern Ontario. Most areas are expected to see rainfall taper off around noon, with some breaks of sunshine developing in the afternoon. London is forecast to reach a high of 6 C, with northeast winds bringing cooler conditions. Atchison says lake-effect precipitation could bring additional showers and even some snowflakes to areas near Georgian Bay and Grey County. Friday will bring a mix of sun and cloud, but temperatures will drop to a high of just 3 C. Saturday will remain mainly cloudy, with a 60 per cent chance of scattered lake-effect showers. The risk of precipitation could affect the Santa Claus parade. Sunday is expected to bring a mix of sun and cloud and a high of 7 C, with sunshine returning early next week.
