December warmth and rain continues to leave southern Ontario in the fog
The last days of the year are going to continue following the same mild and gloomy trend that has shaped December 2023 thus far
Dangerously thick fog is forecast to continue around the Greater Toronto Area (GTA) and the rest southern Ontario throughout Wednesday. Don't worry, though, we're here to help you see through the fog and get you the information you need to know.
Daily records could fall across southern Ontario as southerly winds swirling around a stateside low builds another unseasonably warm day across the region.

It’s been an exceptionally foggy couple of days across southern Ontario as a humid and relatively calm airmass parked over the region.
Visibility dropped to zero at times, making it almost impossible for drivers to navigate roads—especially in the dark. Hamilton endured more than 12 hours of zero-visibility conditions overnight Monday into Tuesday morning.
Unfortunately, the fog threat isn’t going anywhere over the next couple of days, so be extremely cautious while driving as visibility will be reduced. When driving through fog, do not use high-beams, remember to maintain a safe following distance, and don't rush.
Light to moderate rain will continue into Wednesday afternoon through parts of southwestern and central Ontario. Other areas of southern Ontario such as the GTA and eastern Ontario, will see light rain becoming more scattered late day.
The heaviest rain will occur in southwestern Ontario, up towards Grey-Bruce counties, with 20-30 mm of rain, but 15-25 mm of rain is also expected in the GTA and Niagara region. These rainfall totals are for Wednesday and Thursday, but Wednesday will see the most of the rainfall.
Scattered rain will continue on Thursday but the intensity will be lighter and there will be more dry breaks compared to Wednesday.
Southerly winds during a warm pattern are a recipe for broken records—and broken records are a bit of a broken record these days.

Make the most of the unseasonable warmth despite the gloom and threat for rain. Looking ahead, temperatures should steadily fall from their lofty heights as the week wears on. Daytime highs hovering within a degree or two of the freezing mark in Toronto will make for near- or slightly above seasonal conditions through the start of 2024 early next week.
