Rainfall and Fog Warnings in Effect
Toronto faces a soggy Sunday under a Rainfall Warning and a Fog Advisory. A potent low-pressure system is set to drench the city with 20 to 30 mm of rain today, as frozen ground struggles to absorb the water. Ponding on roads and localized flooding in low-lying areas are significant concerns.
Pair that with dense fog reducing visibility to near zero this morning, and it’s a day for extra caution.
Currently, the temperature is 3°C with mist lingering in the air. The humidity is maxed out at 100%, and the barometric pressure is falling at 101.5 kPa. Winds are light at 9 km/h from the north-northeast, and visibility sits at 1.6 km, which might feel generous compared to what’s coming later this morning.
Rain Arrives: Prepare for a Soaker
The rain will start this morning and become heavy by the afternoon. Fog patches will dissipate as the rain picks up. Winds from the east will strengthen to 30 km/h, with a high of 12°C expected. While the temperatures may seem mild, the wet conditions will demand rain gear, waterproof shoes, and a sharp eye on slippery surfaces.
Tonight: Showers Linger
Rain will taper off around midnight, with a further 5 mm of precipitation expected. Winds will shift to the south at 30 km/h, gusting to 50 km/h. The temperature will hold steady at 4°C, keeping the damp chill in the air.
Monday and Beyond
Monday will see a mix of clouds and a 40% chance of showers in the morning. By late morning, showers will return briefly before ending in the afternoon. The high of 4°C will remain steady through the day, but gusty southwest winds at 40 km/h, reaching up to 60 km/h, will make it feel brisk.
Tuesday and Wednesday continue the theme of cloudy skies, with temperatures hovering around 4°C during the day and dipping to near-freezing levels at night. Expect a mix of rain or snow as the New Year approaches, keeping conditions dynamic.
Historical Weather Trivia
December 29 holds some interesting weather history for Toronto. The warmest recorded high was 14.4°C in 1984, while the chilliest low bottomed out at -21.1°C in 1925. Today’s rain may seem tame compared to those extremes!
