Thursday, October 10th 2019, 9:30 pm - The streak of pleasant fall weather continues in southern Ontario, but with some unsettled conditions arriving in time for the Thanksgiving long weekend.
The Thanksgiving weekend is upon us as many southern Ontarians take an early start to the first long weekend of the fall season. While the stretch of gorgeous fall weather lingers into the start of the holiday, a brief hiccup on Saturday could leave some adjusting any outdoor plans. More on the timing of the rain, plus a look at how Super Typhoon Hagibis will keep things cool for the remainder of the month, below.

SIGNIFICANT FALL STORM TO BRING HEAVY RAIN TO NORTHERN ONTARIO
With high pressure remaining draped across the Great Lakes region, the welcomed stretch of mainly sunny skies will continue across southern Ontario, with highs hovering around the seasonal mark right through Friday.
The northwest, however, is seeing the effects of a substantial autumnal storm that began making its effects known on Thursday. While it is expected to bring heavy snow and dangerous blizzard conditions to Manitoba, northwestern parts of Ontario will get strictly rain -- and heavy amounts, too, -- because of the temperature contrast between the two provinces.
Rainfall warnings are in effect for the 50 to 75 mm of rain is forecast for areas around the Lake of Woods. While the weather will remain unsettled in northwestern Ontario until after the Thanksgiving long weekend, Sunday will be the best day to travel.
"Heavy downpours can cause flash floods and water pooling on roads," warns Environment Canda. "Localized flooding in low-lying areas is possible. Watch for possible washouts near rivers, creeks and culverts."
WATCH BELOW: TIMING OF NEXT ROUND OF RAIN IN SOUTH
The streak of sunny days in the south will briefly come to an end on Saturday, as a front crosses the region through the morning hours. This will bring a few hours of rain into the early afternoon before reaching southern Quebec in the evening or overnight hours. Temperatures will drop, particularly in the southwest, where Windsor is expected to only hit a daytime high of 12°C.
The unsettled weather will be shortlived, however as sunshine is poised to return by Sunday, along with a brisk wind and bump in temperatures back to the mid-teens. Similar conditions are expected for the holiday Monday.
STRETCH OF PLEASANT WEATHER ENDS WITH INFLUENCE FROM SUPER TYPHOON
Enjoy the pleasant temperatures while you can, as a significant shot of chilly weather is expected to move in towards the middle to end of next week.
"This will bring periods of rain followed by several days of chilly weather with high temperatures struggling to reach the lower teens Wednesday through Friday," Gillham says. "It looks like the final week of October will bring an extended period of colder than normal temperatures to the Great Lakes region."
This change in the weather pattern is due in part to the track of Super Typhoon Hagibis, which will move into Japan and near Tokyo over this weekend.
While Hagibis will not make the trip all the way across the Pacific to Canada, it will still have a significant impact on our national weather pattern later next week.
"When a typhoon takes a track near or just east of Japan, typically the dip in the jet stream brings colder weather into the Great Lakes region," Gillham explains. "When the track is further to the west -- into Korea or China -- the dip in the jet stream will be further to the west with a colder pattern for western Canada and a warmer pattern for the eastern half of the country."
