If you're looking to catch some rays over the next week or so, Ontario won't be the place to do it. 

A massive low pressure system, spanning over both the United States and Canada, will bring days of unsettled weather to Ontario, starting early next week. 

This relentless weather will be courtesy of an atmospheric blocking pattern known as an omega block.

"This unique weather pattern forces high and low pressure systems to remain nearly stationary," explains Monica Vaswani, a meteorologist at The Weather Network. "This allows for similar weather to continue for a number of days."

What this means for Ontario, is that Monday night through at least Thursday, it will be quite unsettled with-on-and-off showers.

"Don't be surprised if you hear some rumbles of thunder in southwestern Ontario throughout the event,"adds Vaswani. "Some models indicate that there is a potential for this wet pattern to continue into the early part of next weekend,"

This wet system will impact all areas of Ontario, bringing mostly rain to the region. However, residents in northwestern Ontario may see some snow during the middle of the week. 

Rain and cloud cover will keep temperatures cool throughout the week.
