Climate changes are rapidly evolving as the region will be exposed to heavy rains and the storm will reach its peak intensity near the Ontario-Quebec border early tomorrow morning Monday, where it will have the ability to break low pressure records for many areas.

Components are coming together to develop a major mid-winter low, but the problem is that it will be in May.

The cold low is still present over the Great Lakes area, as you may have already noticed. This low will also merge with the Gulf of Mexico disturbance.

When these two weather features are present, a new low-pressure system will rapidly develop, reaching peak intensity near the Ontario-Quebec border early Monday morning.

When analyzing pressure readings, the low forecast is much lower than the average barometer reading in May.

For example, a pressure reading of 980 hPa is very unusual for May in the Great Lakes region.

Some of these records are likely to be broken by Monday.

The effect of this low will pull a low surface accompanied by significant moisture, so localized flooding is possible.

The deeper low pressure area means confirmed gale-force winds will blow in southern Ontario.

There is even a risk of thunderstorms throughout eastern Ontario on Sunday night as unstable air flows into the province.

Lake levels and gale-force winds are closely monitored with the approach of this atmospheric low.

Wind speeds of 40-60 km/h are expected along the northern shores of Lakes Erie and Ontario.

Meanwhile, areas south of Quebec may face winds reaching speeds of 90 km/h before the approaching frontal low on Sunday night.

There will also be winds approaching speeds of 80 km/h, accompanied by the northern winds of the low, especially over Lake Superior.

Additionally, the circulating cold flow will increase the likelihood of a winter mix affecting snow showers in southern Ontario by Monday evening.
