The first significant Great Lakes waterspout outbreak of the season is upon us, as a broad upper level trough creeps across Ontario this week bringing the threat for multiple days of waterspouts, pesky rain showers and isolated pop-up thunderstorms. A chillier temperature trend will also mark the first half of the week, with the threat for frost lingering outside of urban areas.

This week: Pesky rain showers and waterspouts

The fall season certainly wasted no time kicking into high gear, as temperatures took a significant tumble last week, remaining cooler as we start this final week of September.

Along with the cooler, early October-like temperatures, will be the threat for waterposuts as an upper level low pressure system tracks over the warm waters of the Great Lakes sparking the risk for waterspouts to develop.

This specific weather pattern is expected to stick around through Wednesday before pushing east and making way for the return of drier conditions late week and into the weekend with high pressure.

The next round of precipitation expected early next week could be the remnant moisture from Hurricane Ian, however this is not a complete guarantee as not all long range computer models have it tracking into the Great Lakes.

A milder pattern is expected to return and dominate during early and mid October.
