A heavy spring snow came down for parts of the Maritimes Monday evening into early Tuesday morning. A low-pressure system just off the Atlantic coastline brings a further mix of snow and rain into the Maritimes Wednesday.
Snow reports
As expected, the heaviest band of snow came through southern/central areas of New Brunswick as well as western Prince Edward Island. Totals for that part of the Maritimes generally ranged 10-to-20 cm. Northern areas of New Brunswick and eastern P.E.I. picked up a few to several centimetres of snow.
There was a few centimetres of snow for parts of Nova Scotia before a change to rain, with total precipitation amounts of about 8 to 25 mm for that province.
Wednesday night snow and rain
A low-pressure system is expected to develop just east of Cape Cod on Wednesday morning. The low will then move south and east of the Atlantic coastline of Nova Scotia but will come close enough to bring a mix of snow and rain to the region.
Rain will develop in western areas of Nova Scotia Wednesday afternoon. The rain will be developing across that province and P.E.I. Wednesday evening and night. As temperatures fall Wednesday night the rain is expected to mix with or turn to snow.
For most areas the turn to snow isn’t expected to produce much more than one-to-five centimetres. Totals of five-to-15 centimetres are possible for parts of the Eastern Shore of Nova Scotia as well as Cape Breton.
New Brunswick is likely to see a mix of lighter rain and snow from the system with some localized snow totals of one-to-five centimetres.
Inclement weather returns Sunday into Monday
Looking into the extended forecast, the next period to watch will be Sunday into Monday.
A strong low-pressure system moving from the Midwest U.S. into Ontario is expected to bring a warm front across the Maritimes during that time. Current timing shows that Sunday morning and early afternoon are likely to be OK. Weather will be deteriorating Sunday evening, night, and into Monday.
A mix of precipitation is expected, with snow to start, with a transition through a period of ice pellets and freezing rain over to rain.
Currently, northern and central areas of New Brunswick look most at risk of an extended period of snowy then icy weather. It is far enough out in the forecast that there could certainly be some change in how the system is generally expected to impact the region.
