LONDON, ONT. -- Gorgeous weather returned to the region on Thursday but it won’t last, with the weather about to take a turn. 

There is the chance for showers every day for the next week as a stalled frontal boundary will set up shop over the Great Lakes. 

As a result, a subtropical air mass will surge into southern Ontario Friday.  We should get through the morning dry, but the chance for showers and thunderstorms will move in by Friday afternoon. 

There will be a series of low-pressure systems moving through the Great Lakes over the next week under the stalled weather pattern. 

This will generate several rounds of rain and the chance for thunderstorms. 

Rainfall amounts will vary significantly, depending on where the thunderstorms set up.

Most areas can expect to see between 30-50 mm by late Sunday, with some locations under thunderstorms receiving significantly higher amounts.

There will be some breaks this week, and the good news is the temperatures will be warm with high humidity. 

The chance for wet weather is expected to hold right through until Canada Day.
