A slow-moving low-pressure system brought periods of rain to the Maritimes on the weekend and into Monday. A second low-pressure system set to move out of Quebec and into New Brunswick is expected to bring some further April rain and showers to the region Tuesday afternoon into Wednesday morning.
Rain reports
Initially, the most rain with the system fell in western areas of New Brunswick and southwestern Nova Scotia. A number of communities reported totals of 20 to 35 mm. The rain was even heavier for Grand Manan and White Head Islands. An observer at White Head reported a rainfall of 52 mm and an observer at Grand Harbour reported 38 mm.
The steadiest of the remaining rain is falling in Cape Breton Monday. Parts of Cape Breton and Victoria Counties have received rain amounts of 14 to 24 mm, with an additional 5 to 10 mm to come. A rainfall warning was issued for Cape Breton and Victoria Counties.
Looking at select weather station sites in the Maritimes, the month seems to be on track for near normal amounts of April precipitation. The soggiest conditions so far have been in western mainland Nova Scotia. April is about middle of the road for total precipitation in the Maritimes – it is neither one of the highest precipitation months nor one of the lowest.
More wet weather
As above, a second low-pressure system will move from Quebec and into New Brunswick Tuesday into Wednesday.
Expect some scattered showers to develop in western New Brunswick and western Nova Scotia by Tuesday afternoon. Rain, drizzle, and fog will develop across the Maritimes Tuesday evening and night.
Parts of northern New Brunswick can expect the rain to mix with or turn over to a wet snowfall late Tuesday night into Wednesday morning. Snowfall Warnings have been issued for areas such as Campbellton, Bathurst, and Mount Carleton where as much as 15 cm could fall.
Special weather statements have also been issued for the Acadian Peninsula and Miramichi where 10 to 15 cm of snow is possible.
Rain, drizzle, and fog will continue into early Wednesday morning. By Wednesday afternoon the region will be down to some scattered showers and flurries.
Rain amounts of about 5 to 10 mm can be expected for Nova Scotia and most of Prince Edward Island. New Brunswick and Prince County, P.E.I., can expect about 15 to 30 mm of precipitation. Remember there will be some wet snow in some of the northern most areas of New Brunswick.
Looking ahead
A trough of low pressure lingers over the Maritimes on Thursday. Partly cloudy skies and some isolated showers can be expected.
A weak ridge of high pressure builds over the region Friday. Expect a mix of sun and cloud and likely one of the fairest, mildest weather days of the week.
A low-pressure system moving through Quebec pushes a warm front into the Maritimes on Saturday. Rain and showers will likely return Saturday afternoon into evening and night.
None of the weather systems expected this week look to be unusually strong or persistent for this time of the year.
