More snow is on its way for New Brunswick and in a similar fashion to last week’s storm, Nova Scotia can once again expect mostly rain with the possibility of a bit of snow mixed in. The incoming system will be a mix of an Alberta clipper coming through Ontario and a secondary low from New England, and it will be another short blast of winter for the region, with the entire event spanning 24 hours.
Things will start off around midnight tonight as snow from the Clipper pushes its way into New Brunswick. As the snow spreads eastward across the province through the early morning hours, the low from the States will merge with the Clipper, which will funnel even more moisture northward from the Gulf. This secondary source of precipitation will reach Western Nova Scotia in the pre-dawn hours. The merging of these two systems will result in some intensification starting later in the morning, leading to heavier snow and rain across the region.
Nova Scotia
Nova Scotia will once again find itself in the warm sector of this storm, leading to precipitation falling mostly as rain for the duration of this event. However, there is a chance for some snow showers since temperatures will be hovering just above the freezing mark in some areas along the leading edge of the storm. Unfortunately for snow lovers, no real snow accumulation is expected from this storm, with temperatures climbing throughout the day and resulting in any snow transitioning to rain. The exception to this is, once again, in the higher elevations of Cape Breton where temperatures will remain below 0°C until Thursday evening, leading to 5-10cm of snow. Widespread rainfall totals across the rest of the province are expected to be in the 20-40mm range.
New Brunswick
On the other hand, New Brunswick can expect to need the shovels at some point on Thursday. The snow from the Clipper will push its way across the province throughout the early morning, but as the rain reaches Nova Scotia, it will also push into the Fundy Coast area, limiting snowfall accumulation along this stretch. Once the two systems merge and the storm intensifies, snowfall rates could approach 3cm per hour in the afternoon across Central and Northern New Brunswick, leading to widespread snow accumulations above 10cm. In the early and mid-afternoon, warm air will wrap around the backside of the storm, resulting in a transition from snow to rain that will push northeastward into the evening. Temperatures will fall overnight, but the warm air, along with the rain, will result in the melting of some of the fresh snow across most of the province.
Prince Edward Island
The leading edge of the precipitation will reach Prince Edward Island around noon on Thursday, with some light snow that will last for several hours. This will bring up to 5cm of snow across the Island before the warm air moves in and the snow switches over to rain. Similar to New Brunswick, the warm air and rain will melt most, if not all, of the freshly fallen snow across the province throughout the evening.
The storm will start to dissipate in the early afternoon, with the arrival of the warm air in New Brunswick and it will fully exit the region shortly midnight and into Friday morning. There could still be some lingering flurries or pockets of light rain throughout early Friday morning.
