Londoners will need to dust off their snow shovels.
Environment Canada has issued a snow squall watch for London and Middlesex County with lake effect squalls expected to develop off of Lake Huron early Wednesday and continue into Thursday. The snow squalls could dump between five and 15 centimetres across the region.
A snow squall watch has also been issued for Huron-Perth.
"While visibilities will be significantly reduced at times, heavy accumulations of snow are not expected as shifting winds will prevent the snow squalls from lingering over any one location for an extended period of time. The exception to this will be in areas near and north of London where the snow squalls are likely to remain near stationary for much of Wednesday night," the national weather agency said on its website.
Drivers are warned travel may become dangerous because of the winter weather, with roads, walkways and parking lots becoming difficult to navigate due to accumulation.
The squalls are expected to taper off during the day Thursday.
