A passing cold front has cleared out of southern Ontario, dropping temperatures considerably, such that Sunday will be as much as 10 degrees cooler than Saturday, and the Thanksgiving Monday will be on the cool side as well. The upside is that the remnants of Delta look to stay too far south to have more than a minimal impact on Monday, and most of the day will be dry. A closer look, below.
- Sunday noticeably cooler in the wake of the cold front
- Most of Delta's remnants will remain stateside holiday Monday, some chance of showers in eastern Ontario
- Monday evening and overnight sees a front bring more widespread showers into Tuesday morning
SUNDAY: TEMPERATURES TO DIVE, WINDS SHIFT, PICK UP
We hope you got a chance to soak up some of the warmth on Saturday before the cold front passed through. In its wake, Sunday's daytime highs look very different, in fact as much as 10 degrees colder, sitting squarely in the low to mid-teens, with the warmest temperatures in the southwest.
It will be a touch windy as well, with gusts of 30-40 km/h through the day near the lake shores.
The upside is that most of the south looks to feature fair conditions. However, as colder air overrides the warmer waters of Lake Ontario, the easterly wind will bring the chance for some light lake-effect showers to the western end of Lake Ontario
MONDAY: MOST OF DELTA REMNANTS TO STAY SOUTH
While there was some uncertainty earlier in the week in the Thanksgiving Monday forecast in Ontario because of the track of Delta, the forecast is now for it to remain south of the province.
Presently, the storm's only real effect on Ontario looks to be some cloud and showers by the afternoon for parts of eastern Ontario, and even then, most of the day will be dry and such showers as there will be won't be a washout by any means.
More impactful will be a cold front moving through in the evening and overnight hours Monday, but it is not expected to bring much in the way of totals, remaining in the 5-10 mm range.
Rain will move out in the GTA by the pre-dawn hours Tuesday, while it will linger in eastern areas into the morning.
Check back for updates as we continue to monitor the effects of Delta.
