Quickly accumulating snow, difficult travel hits Ontario and Quebec

Drivers across southern Ontario and Quebec are facing slower commute times on Monday, as a widespread swath of snow threatens reduced visibilities and tricky travel. Relatively mild air is tracking into the region as well, which means that a mix of snow and rain is possible at times, which could cut into overall totals. Snowfall amounts will range from 5-10 cm for inland regions, but pockets exceeding 10 cm are certainly not out of the question for areas further north. Monday's snow is just the first round in an active pattern setting up for the week, with additional precipitation chances persisting through Wednesday. More on the timing and impact for this final week of February, below.

WEATHER HIGHLIGHTS:

  • Snow reaches GTA Monday morning, up to 10 cm of snow expected for some

  • Milder temperatures forecast Monday, rising above freezing across the region, could lead to rain-snow mix along lake shores

  • Unsettled weather continues for the first half of the week

MONDAY: ROUND OF WIDESPREAD SNOW THREATENS TRAVEL ACROSS ONTARIO AND QUEBEC

An active start to the week is underway, as a system is bringing widespread snow to southern Ontario and Quebec on Monday.

Environment Canada issued winter travel advisories for most of southern Ontario early Monday, warning of impact to commute times as the snow quickly accumulates and reduces visibility.

"Motorists are advised to exercise caution and alter their travel plans as needed," EC says in the statement.

A southerly flow with this system will bring in a bit of milder air and the chance for mixing in some areas, particularly near the shores of Lake Erie and the Niagara Peninsula. This also means snow accumulations for most areas will not be exceptional.

A widespread 5-10 cm is expected for inland areas, but pockets of 10 cm are possible, especially over high terrain and along the escarpment. Areas that see some mixing with rain will cut into the totals and will see less than 5 cm accumulate.

"Still, snowfall rates will be heavy at times, leading to travel complications and periods of low visibility," warns Weather Network meteorologist Michal Carter.

Police officials say they responded to about 75 crashes over the last 24 hours, with about two dozen occurring through the early morning commute on Monday. Most schools remained open across the region, though buses were cancelled in Dufferin-Peel, Simcoe County, Guelph and Wellington and Waterloo regions, due to the poor travel conditions right in time for the morning commute.

Snow will subside from west to east across much of Ontario early Monday evening, though still continuing for the Ottawa region and into Quebec through early Tuesday morning.

WEEKLY OUTLOOK: REMAINING UNSETTLED WITH MULTIPLE SYSTEMS, MILDER TEMPERATURES

Conditions are expected to remain unsettled beyond Monday, as a couple of weak clipper systems bring additional precipitation chances through the first half of this week.

The first, on Tuesday, will bring the chance for an additional 3-5 cm of snow in some areas. Wednesday will see another system, but with more mild air potentially in the mix, southern areas will see more rain mixing in.

By the end of the week, high pressure and fair conditions are expected to re-establish, with temperatures sitting closer to seasonal values for Thursday and Friday before another climb heading into the week.
