Showers, thunderstorms and a sharp drop in the temperature

We can expect a sharp temperature change in the region on Friday as a cold front moves through.

Showers and thunderstorms are expected across the area, according to CTV News London Meteorologist Julie Atchison..

"There is the potential for 10-15mm [of rain] if we get under one of these heavier thunderstorms," she said. "As the cold front moves off to the east and the air comes in from the north west behind the front, it will generate lake-effect showers downwind of Lake Huron."

By the noon hour in the London area on Friday, the temperature will peak around 19 C with the temperature dropping to 13 C on Saturday.

"Around 20 C on Sunday, mainly sunny with lots of sunshine on Monday and then temperatures recover," said Atchison.

The normal high for this time of year is around 23 C and the low around 12 C.
