Ontario: Widespread light snow a back
Many across southern Ontario will see 5 to 10 cm of snow as the latest system tracks through the region.
Scattered snow showers are playing hide-and-seek with southern Ontario's sunshine on Sunday, but the main snowy event is still to come. A system tracking through starting late Sunday afternoon will bring widespread light snow to the region that will have you reaching for at least the snow brush, if not the shovel, for your Monday morning commute. Beyond that lies a week of variable temperatures and shots of unsettled weather as we head toward Family Day weekend. We take a look at what you need to know for the week ahead below.
WEATHER HIGHLIGHTS:

THROUGH EARLY MONDAY: SNOWY SYSTEM TO START WORKWEEK
While scattered flurries and snow showers will dot southern Ontario through much of the day on Sunday, the next major weather-maker is set to slide into the province through the evening and overnight hours into Monday. This clipper-type system will live up to its name, moving quickly through the region overnight, but it will drop some noticeable accumulations as it goes.
The first flakes move into southwestern Ontario through Sunday evening, reaching the GTA before midnight and spreading across the rest of southern Ontario through the overnight hours.
MONDAY MORNING/AFTERNOON: SNOW TAPERS OFF, TEMPERATURES REBOUND SLIGHTLY
The good news for the Monday morning drive is that the worst of the snow moves through before dawn, except for around the Ottawa Valley, where some additional accumulations are still expected after sun-up.
All told, accumulations will be on the light side -- around 5 to 10 cm -- across most of the region. Slightly higher amounts are likely where the still-open Great Lakes enhance snowfall rates, mainly around the shores of Lake Huron and Georgian Bay, and over eastern Ontario and the Ottawa Valley. Lesser amounts are expected closest to the lake shores, where some mixing with rain is possible through the overnight.

Snow will have tapered off for everyone by the mid-to-late afternoon. On another positive note, a change in the winds will also bump temperatures back up to seasonal for Monday afternoon, with highs in the low single digits for most.
LOOK AHEAD: TEMPERATURE SWINGS WITH ACTIVE PATTERN INTO MID-FEBRUARY
While much of the week will be mild (at least by early February standards), that warmth doesn't seem set to take us into the long weekend.
Another round of flurries or showers is likely through midweek, thanks to a weak disturbance drifting through the Great Lakes region. But it isn't until late week that forecasters are watching for another round of active weather.
Early model guidance suggests a low pressure system moving up the U.S. Eastern Seaboard will bring precipitation back into southern Ontario for Thursday. However, the exact track of this system will determine whether that comes in the form of rain or snow. Either way, colder air is set to descend behind the system, dropping temperatures by as much as 10 degrees across the region for Friday and Saturday.
