We will smash historic record high temperatures early this week as the mercury climbs into the upper 20s. However, colder air is building in Northwestern Ontario and will finally flood into the Sault region at the end of this workweek. Daytime highs will literally be cut in half by the end of this week and be lucky to climb above 10°C this coming Thanksgiving weekend.
The drastic change in temperatures marks the beginning of a shift in the overall recent weather pattern. Gone will be the sunshine and heat, replaced by plenty of clouds and rain. A chance of rain is in the forecast from Thursday right through (and beyond?) the Thanksgiving Weekend.
Scattered storms rumble across the region early Monday morning, giving way to afternoon sunshine. Southerly winds then help push temperatures up to 27°C, close to the record-high for this date.
Sunshine continues into Tuesday, and we will break the record high of 24°C set in 2005 with daytime highs near 27°C.
Sunshine continues for one last day into Wednesday, again with record-breaking temperatures near 27°C. Rain and storms arrive in the evening and continue overnight.
Thursday looks cloudy with showers and the chance of a storm, as daytime highs slip to 19°C. We might see some sun Friday afternoon, but a cool northwest wind drops temperatures to 15°C. Even colder air arrives on Saturday and Sunday on a north wind.
