We're watching for a potential snowstorm that could impact parts of Atlantic Canada by the end of the week, with an uncertain track yielding two possible scenarios

The unsettled pattern will continue across much of Atlantic Canada this week, keeping the region stuck in a stubborn and gloomy cycle.

This comes after parts of the East Coast saw minimal precipitation in much of this fall, resulting in lower-than-normal water levels in Lake Major.

Potential tracks for Atlantic Canada system, two scenarios

The next scenario will come from a forthcoming Colorado low, which is expected to become a messy storm as it intensifies and tracks into Atlantic Canada late this week.

This week:

There are two scenarios on where the low will track.

The first scenario has the system moving south of Nova Scotia, bringing the heaviest snow into northern areas of the province and southern New Brunswick.

The second would see it track through the Bay of Fundy and brings the heaviest snow into New Brunswick. It still brings snow to Nova Scotia, but wouldn't be as heavy.

These two scenarios can bring some locations from seeing accumulating snow to snowblower amounts, so check back with The Weather Network soon as we continue to monitor the situation.
