Chilly and Unsettled: A Wet Long Weekend Ahead in Ontario

As southern Ontario gears up for the Thanksgiving long weekend, residents can expect a sharp drop in temperatures and unsettled weather. What began as a pleasant start is set to take a dramatic turn, bringing chills and even the possibility of some early snow.

Forecast Overview

This holiday weekend, southern Ontario is facing a notably chilly weather pattern. A low-pressure system will sweep across the region, leading to the coldest temperatures seen since last spring. Temperatures may remain in the single digits, making outdoor plans rather brisk.

Key expected weather conditions include:

• Rainy weather with the possibility of brief wet snow at higher elevations.
• Gusty winds ranging from 30 to 60 km/h, particularly felt across the Golden Horseshoe.
• Variable precipitation patterns with uncertainty about the extent of rain and snow.

Details for Sunday and Monday

As the low-pressure system approaches on Sunday, residents should prepare for raw and uncomfortable conditions.

• Sunday’s Weather: The day is expected to start off with noticeable chill. Northeasterly winds will develop, contributing to cold conditions across the region.
• Precipitation Patterns: Areas around Niagara and Lake Erie may experience the heaviest rain, with lighter showers expected to reach the Greater Toronto Area (GTA). The combination of rain and dropping temperatures may even lead to wet snow mixing in at higher elevations.

Monday’s Conditions

On Monday, while the chances of precipitation may diminish in the GTA, eastern Ontario can still expect ongoing showers.

• Temperature Struggles: Many areas across southern Ontario will have difficulty reaching double digits. A failure to surpass 10°C in Toronto would mark the first single-digit day since April 25.
• Local Changes: Ottawa will feel the chill too, facing its coldest day since early April.

Unseasonably Early Winter Weather

As the low-pressure system moves eastward by late Monday, the winter-like weather might not be finished just yet.

• Lake-effect Showers: Residents can anticipate scattered lake-effect showers through Tuesday as colder air moves in.
• Flurries Possible: Some areas, particularly along the escarpment and cottage country, may see occasional flurries during this period. While some mountain regions are positioned to receive a light dusting of snow, substantial snowfall is unlikely.

Cottage country may experience mixed precipitation, especially in places like Dundalk Highlands, where elevations reach about 526 metres.

Prepare for the Cold

With this chilly forecast, residents should make sure to dress warmly if they plan on venturing outdoors over the long weekend. Whether it’s heading out for a turkey feast or a walk with family, following these tips can ensure a comfortable outing:

• Wear layers to trap heat.
• Bring a warm beverage to stay cozy.
• Check weather updates frequently to stay informed about changing conditions.

Conclusion

This Thanksgiving weekend in southern Ontario, the transition from fall warmth to winter chills is evident. With the threat of rain, gusty winds, and even the early hint of snow, it’s crucial for residents to remain prepared. As temperatures dip and conditions become unsettled, embrace the season with warm clothing and a readiness for whatever weather comes your way
