A taste of fall as low-pressure stalls
September is often a month of transition for our climate and weather patterns – we’re holding onto the last bits of summer while starting to see elements of fall.
The pattern will be very fall-like the next few days with cooler temperatures, showers for some and plenty of wind.
The unsettled weather is the result of low-pressure that is currently stalled near southern Labrador and will slowly move northeast of Newfoundland later this weekend. The low is dumping over 100 mm of rain on western Labrador while also bringing some wet snow to parts of that region.
The wraparound circulation is also developing broken showers across Newfoundland and will bring some off-and-on showers to Cape Breton, Prince Edward Island and potentially the North Shore of Nova Scotia and Acadian shores of New Brunswick through Friday, potentially lingering Saturday in Cape Breton.
It’s otherwise dry elsewhere, but cool air being drawn into the system has high temperatures only in the teens.
The wind is another factor. West to eventually northwest winds will gust 40 to 60 km/h for Nova Scotia, Prince Edward Island and New Brunswick on Thursday and Friday, with the likelihood that gusts will reach 60 to 80 km/h on north-facing coastlines in Nova Scotia, including Cape Breton, Prince Edward Island and New Brunswick.
Wind gusts of similar ranges are forecast for Labrador, but it won’t be until later Friday and Saturday through Sunday that these winds affect Newfoundland.
High pressure will attempt to settle the pattern gradually this weekend into early next week, but I’ll be watching a weak trough that might bring some additional showers to the Maritimes Sunday.
Hold onto your hats, and maybe enjoy a hot pumpkin spice beverage.
