Low-pressure to stall offshore next week
The latest storm to wreak havoc in our region is clearing eastern Newfoundland with a nice ridge of highpressure in its wake.
It’s serving up lots of sunshine to the Maritime provinces and western Newfoundland and will bring nicer weather to eastern Newfoundland on Sunday. However, it’s not sticking around and will help stall low-pressure offshore next week.
Precipitation arrives from this low in the western halves of Nova Scotia and New Brunswick later Sunday morning to afternoon, spreading east in those provinces and into Prince Edward Island late afternoon through Sunday night.
It will approach southwestern Newfoundland on Monday and spread north and east Monday night into Tuesday.
Snow is possible on the leading edges, especially over higher terrain, but should be rain first for most.
However, as it draws cooler air from northerly winds, we can expect mixed periods of rain or snow through the middle of the week.
Precipitation amounts will be variable during this threeday period.
Nova Scotia, P.E.I., southern New Brunswick, plus the south and east coasts of Newfoundland have the best odds of seeing total rainfall between 10 to 30-plus mm.
Snowfall mainly from the initial weather could total 10 to 30-plus cm for northern New Brunswick, the Cape Breton Highlands, and parts of Newfoundland — especially central.
Two to 10-plus cm is also possible in the rest of Newfoundland, P.E.I., as well as higher elevations and some interior regions in Nova Scotia such as the Annapolis Valley and North Shore Tuesday to Wednesday.
Weather conditions improve Wednesday and Thursday for the Maritimes, and through Thursday into Friday for Newfoundland and Labrador.
However, this active pattern looks set to continue for the second half of the month as it’s showing no signs of quieting down.
