Up to 40 mm rain: Storm track puts Atlantic Canada in for a damp week
Canada's East Coast can expect several rounds of rain and cooler temperatures as air masses collide over the region this week
A battle between Arctic and Gulf air will leave Atlantic Canada in the crosshairs as multiple rounds of rain are forecast throughout the week.
The soggy pattern will be thanks to a hot and muggy, high-pressure system stalled over the southeastern United States, where daytime highs are in the 30s, and a freezing high-pressure system over Hudson Bay. The result? A conveyor belt of active weather aimed right at Atlantic Canada.

A widespread 20-40 mm of rainfall is forecast across Newfoundland and the Maritimes through the week, with locally higher amounts possible across southern Nova Scotia and along Newfoundland's coast.
The active storm track will come in three rounds. Round one kicked off on Monday with Hurricane Isaias's remnants spreading showers over the region. Tuesday will see those showers ease into light rains, but the damp cool will persist as a new system makes its way in for round two on Wednesday.
Round 2: Heavy rainfall, thunder moves in Wednesday
Moderate to heavy rainfall is expected to spread across the Maritimes through Wednesday morning as this second system makes its way east. The steady rain should begin to clear out through the afternoon, but we could see some showers return in the overnight.
There will also be a risk of isolated thunderstorms across Nova Scotia through the day, starting west of Halifax in the morning and shifting east of the city by the afternoon.
By late Wednedsay, the system will make its way into Newfoundland, bringing steady, moderate rainfall across the province through the overnight hours.
The steady rains should ease across Newfoundland through Thursday afternoon, but colder air behind the system could bring residual rains mixed with snow across western and interior parts of the province before ending in the evening.
Winds will remain gusty across Atlantic Canada through the day Thursday.
Round 3: Saturday brings on the main event
Several forecast models are indicating that a third low-pressure system will swing through Atlantic Canada through the start of the weekend. This round could very well be the strongest of the week as it holds the potential for widespread rain and gusty winds.
Some wintry precipitation is also likely on the backside of the low, as it pulls in the freezing air from the north.
