A snow squall watch has been lifted for London and Middlesex County but a weather advisory is in place as heavy flurries are still possible Tuesday evening.
On Monday, Environment Canada issued a snow squall watch for London, Parkhill, and Eastern Middlesex County, as well as for Grey-Bruce, Huron-Perth, and Barrie-Orillia-Midland.
On Tuesday, a snow squall warning was issued for Huron County and snow squall watches were added in Oxford-Brant and Waterloo-Wellington, before all of the watches were lifted by 3:30 p.m. and replaced with either snow squall warnings or weather advisories.
As of 3:30 p.m. Tuesday, weather advisories were in place for Barrie-Orillia-Midland, Dufferin-Innisfil, Perth County, London-Middlesex, Oxford-Brant, and Waterloo-Wellington.
Snow squall warnings were in place in Huron County and Grey-Bruce counties.
In areas with snow squall warnings, the weather agency says 15 to 20 cm of snow in 12 hours is possible and visibility could be significantly reduced.
The weather advisories, meanwhile, suggest five to 15 cm of snow is possible with brief periods of low visibility.
While the daily high is expected to only reach 1 C on Tuesday and Wednesday in London, it’s expected to climb to 9 C on Thursday and 11 C on Friday.
