Southern Ontario: Fall Weather Hazards Outlook for Saturday, October 23, 2021

Forecast Discussion

Another chilly start to the day is expected for Saturday morning across Southern Ontario. This will also bring the risk for frost in some areas including Central and Eastern Ontario primarily along the Quebec border and higher elevations to the northwest of the GTA. A few days ago it looked like there might be the potential for the season’s first flurries in more northern parts of Southern Ontario. However, there is a lack of precipitation during the time when the temperatures are favourable for flurries. So right now it seems unlikely but we can’t rule it out if we get some lake effect precipitation around Georgian Bay.
