December has witnessed notably cold temperatures in Southern Ontario. However, predictions indicate a potential thaw, likely affecting the chances of a white Christmas.
Understanding the Weather Patterns in December
Traditionally, a La Niña winter leads to persistent Arctic air in Central Canada. This year, such conditions have been prevalent, influencing weather patterns across the region. The prevailing system has redirected storms towards the Atlantic coast and limited their movement near the Great Lakes.
This situation has made it difficult for warm air to penetrate Ontario. However, the latest forecasts suggest a shift in this trend. Storms currently tracking north of the Great Lakes may bring warmer conditions.
Key Temperature Records
Recently, Fort Frances in northwestern Ontario recorded an impressive temperature of 9.0°C. This figure stands as the highest temperature for the province this December.
Implications for a White Christmas
The continuation of this warming trend will likely decrease snowfall, especially in areas like the Greater Toronto Area (GTA) and the Highway 401 corridor stretching from Windsor to Cornwall. While snowbelt regions possess sufficient snow to maintain a white Christmas, confidence levels in other areas are falling.
Upcoming Weather Predictions
- A few clipper systems are forecasted for next week and late December.
- These systems may bring fluctuating temperatures and windy conditions.
- Storms south of the Great Lakes will likely be less frequent.
As this weather pattern develops, Southern Ontario residents should prepare for changing conditions, closely monitoring forecasts to assess the likelihood of a festive white Christmas.
