A 'Rex block' is in store for London, Ont. Here's how the weather pattern will impact the region

The birds are singing, the bees are buzzing, and the sun is shining throughout the region. But the risk of frost still lingers, with Environment Canada issuing a frost advisory Wednesday night and into Thursday for Grey-Bruce and Huron-Perth.

At least seven straight days of sunshine is on the way for the London region.

Temperatures will range from 18 C to nearly 30 C between Thursday and next Wednesday.

Clear skies will remain overnight with the coolest night being Thursday, with the potential for frost.

Overnight temperatures remain well above the freezing mark over the weekend and into next week.

The region will then be on the receiving end of multiple days of sunshine and soaring temperatures.

According to CTV News Meteorologist Julie Atchison, a Rex block, which prevents other weather systems from moving through the region, will set up over the area and remain stationary.

“This type of weather system occurs most often in spring, as high pressure is located north of low pressure and the system remains locked in place,” said Atchison.
