More snow ahead for the weekend, amid continued cold temperatures

A very cold week ended with some very hefty snow squalls for communities along the western end of Lake Ontario, with some squalls poised to continue overnight. Beyond, Saturday features a system that will bring widespread, though light, amounts to most of the province, but the Golden Horseshoe is once again at risk of heavy squalls. What to expect, below.

WEATHER HIGHLIGHTS

  • Weak system to bring widespread snow Saturday, lake-enhancement for western end of Lake Ontario once again

  • Remaining cold in southern Ontario this weekend, wind chills near -20 for some areas

  • Watching potential system next week

WEEKEND: COLDEST TEMPERATURES OF THE WINTER SO FAR, WIDESPREAD SNOW DEVELOPS WITH LOCALLY HEAVY AMOUNTS

After the very heavy snow from Friday's squalls in the Golden Horseshoe, the province as a whole will see a shot of widespread Saturday, as well as another narrow band of heavier lake-enhanced snow near the west of Lake Ontario.

Most of the GTA will see 5-10 cm of snow, with less than 5 cm expected north of the region. However, localized snow totals of 10-20 cm are possible near the west end of Lake Ontario, due to the band of lake-effect snow.

In fact, some of Saturday's squalls were so long-lived they may last into early Saturday morning for some communities along the Golden Horseshoe.

"Travel may be hazardous due to sudden changes in the weather. Visibility may be significantly and suddenly reduced to near zero," Environment Canada says. "Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow."

Temperatures will also continue to be very cold, with the weekend featuring daytime highs that will struggle to reach even the negative single-digit mark, with wind chills once again down to -20.

BEYOND: POTENTIAL SIGNIFICANT SNOW FOR TUESDAY

A more significant storm is possible on Tuesday for southern Ontario, as a major winter storm for the eastern U.S. tracks south of the border, but also close enough to bring widespread snow into Ontario.

According to Weather Network meteorologist Dr. Doug Gillham, there's also an increasing potential for a weaker system ahead of the main storm that could bring a widespread snow on Monday as well.

"Snow totals of 10-20 cm are possible for much of southern Ontario through Tuesday," Gillham says, adding that there's also another system later in the week that bears watching.

While this late week system is still several days out, and there's low confidence in the snow forecast, it'll still be a storm to keep an eye on.

"Because if this storm verifies, our 7-day snowfall totals for parts of southern Ontario could be rather impressive with the parade of storms," says Gillham.

At this point it looks like near normal or colder than normal temperatures will dominate for the rest of the month of February.
