After overnight thunderstorms broke out in the first with a rainy season, there will be more similar by Sunday, although the risk of severe weather will be concentrated in eastern Ontario and southern Quebec. Meanwhile, a gradual rise in temperature is heading for Central Canada this week. What you need to know about the threat of Sunday’s storm and next week, below.

SUNDAY: MULTIPLE ROUNDS WITH RAIN, SOME RISK OF SEVERE THUNDERSTORM
A low-level swing in northern Ontario and Quebec will lead to a wet Sunday for much of central Canada. Early Sunday morning liquid conditions are possible for the Golden Horseshoe.

Consider these five gifts Meanwhile, several rounds of torrential rain are likely to sweep the eastern Great Lakes during the day on Sunday, but southern Ontario will take a decent break from the late afternoon rain with a mixture of sun and clouds as drier conditions prevail. . However, as we wait for clearing until the afternoon, there is a possibility of isolated emerging storms, but they will be extremely sparse in nature. There is also the risk of embedded storms, with widespread threat from southwestern Ontario to central and northern Quebec. Some of the thunderstorms in eastern Ontario and southern Quebec could be very close, with light hail and heavy rain being the main threat with the strongest built-in storms. These areas are more likely to see stronger storms capable of rotating, as there is little shear in the atmosphere and they will also move fast. We can expect additional rainfall of 5-10 mm throughout southern and eastern Ontario, with higher amounts likely at a holiday home and further afield in Quebec. Locally stronger overall are likely in storms. The high temperatures will come immediately seasonally with the result that the sun will appear in the middle of the clouds in the late afternoon.
THIS WEEK: A HEATING TRENDS FOR CENTRAL CANADA
While Monday will be a pleasant day for the region, southwestern Ontario could be at the end of an Intermediate Transmission System (MCS) on Monday night as it rotates southeast across the Midwestern United States. If it does affect the area, it is likely to rain and thunderstorms in areas near the U.S. border and along the west coast of Lake Erie Monday night through Tuesday morning. Meanwhile, a heat wave south of the border will begin to affect our weather this week. Several days of off-season temperatures are likely next week in southern Ontario and Quebec, with daytime highs in the 1920s to close to 30 possible in some areas. However, east winds off Lake Ontario would likely keep the greater Toronto area cooler throughout. The heat could also fuel the risk of thunderstorms at times next week. We are also tracking the schedule of a cold front towards the end of next week that will help reverse the heat and reduce temperatures towards next weekend.
