Cooler temperatures bring frost warning
Environment Canada issued its third frost warning this month for Halton, Peel, York and Durham regions on Tuesday, but the City of Toronto has been spared yet again.
“The concrete and asphalt tends to keep our temperatures higher in the core of the city as opposed to the suburbs,” said Geoff Coulson, meteorologist with Environment Canada.
The clear skies and winds expected Tuesday overnight will be key ingredients in the development of frost Wednesday morning in the GTA, where temperatures may dip to a degree or two below freezing.
Coulson says gardeners will want to protect their vulnerable plants by wrapping or watering them before night falls, to provide some extra insulation against the cold.
Suburbanites will also want to wrap themselves up, particularly if leaving the house early in the morning.
“We’re now fully into the season of layers,” said Coulson.
The frost is only a threat Wednesday; increasing cloud coverage and daytime temperatures will help keep the nights warm at least until the weekend.
"We’re entering into what we would expect for this time of year – fall-like weather - but that doesn’t preclude us from getting a fair amount of sunshine,” said Coulson. Saturday and Sunday will see temperatures climb to 16 C.
