Significant Rainfall and Temperature Plunge Forecast for Southern Ontario This Week
Southern Ontario is bracing for a dramatic shift in weather conditions this week, with Environment Canada issuing advisories for heavy rainfall and a subsequent sharp drop in temperatures. The forecast predicts a challenging period for residents across the region, from Windsor to Cornwall.
Heavy Rainfall and Flood Risks
According to Environment Canada, a series of low-pressure systems will bring significant rainfall to parts of southern Ontario, starting Tuesday night and continuing through Wednesday. Toronto is expected to receive between 20 and 40 millimetres of rain during this period.
The weather agency has warned that heavy downpours may lead to flash floods and water pooling on roads, prompting potential rainfall warnings. In some areas, such as the Bruce Peninsula and parts of central Ontario, a prolonged period of freezing rain is anticipated, while Petawawa could see up to 10 millimetres of rain.
Temperature Drop and Winter's Return
Following the rainy conditions, temperatures are set to plummet later in the week. After enjoying sunny weather on Sunday and Monday, Toronto will experience a high of 13°C on Tuesday, with a low of 5°C in the evening. Wednesday will see a high of 11°C before dropping sharply to -3°C at night.
By Thursday and Friday, temperatures will fall further to around 1°C, with Environment Canada noting that flurries may also arrive on these days. This marks a stark contrast to the earlier mild conditions, reminding residents that winter is not quite finished yet.
Messy March Weather Patterns
March is notoriously unpredictable in Toronto, often showcasing all four seasons within a single week. It is common to see people wearing parkas and waterproof jackets simultaneously on the streets during this month.
Winter tends to linger stubbornly, with occasional hints of springtime. Temperatures typically hover around freezing, creating slushy conditions. The month is also known for its wet weather, with freezing rain being a common risk due to warm fronts colliding with lingering cold air.
Skies are often grey and overcast, though increased daylight hours make it less gloomy than January and February. Interestingly, areas closest to Lake Ontario generally experience cooler temperatures compared to northern parts of the Greater Toronto Area, such as Richmond Hill or Vaughan.
Residents are advised to stay updated on weather alerts and prepare for potentially hazardous driving conditions due to the expected rainfall and temperature fluctuations.
