It seems as though the storm from the weekend isn’t quite finished with the Maritimes. There have been scattered flurries across the region throughout the day Tuesday, but more organized bands of snow are on their way.

The snow will move into Northern New Brunswick from the north early Wednesday morning and spread southward into the region. By sunrise, the snow will reach Prince County, PEI and then Northern Nova Scotia by the early afternoon. This band of snow will last for up to 12 hours, but the snow will be light and come in bursts, resulting in up to 5cm of accumulation.

In the late afternoon and early evening, a second band of snow will push southward into Northern New Brunswick and following the same path as the first. This round will bring another 12 hours of steady snow across the region before starting to dissipate early Thursday morning. There will be pockets of heavier snow in this second wave, which will drive snowfall totals above 10cm in some parts of the Maritimes.

The snow will taper off throughout Thursday morning, but in the late morning to early afternoon, one final round of precipitation will move in. This third and final round will arrive after temperatures climb above freezing, resulting in mostly rain falling, but a bit of snow mixed in, across the Maritimes Thursday afternoon and into early Friday morning.

From these three rounds of precipitation, we’re looking at widespread snowfall totals of 5-20cm across the Maritimes. There will be areas where the snow will persist into late Thursday morning from the second round of snow, particularly the Annapolis Valley and at higher elevations in Northern New Brunswick. There will also be areas where more snow than rain will fall in the third round, namely the Northumerland Shore and the Cape Breton Highlands. The Highlands will see the most snow, up to 30cm, due to steady and often heavy snowfall over the duration of this event.
