High-pressure’s finally arrived, but it’s still not sunny for everyone
ALLISTER AALDERS
We’re welcoming May with a big change to the overall weather pattern. A highpressure ridge has finally pushed that trough that was stuck with us for days out. Good news, right?
On a larger scale, yes, but on a localized scale, this is not leading to sunshine and warmth for everyone.
Much of Newfoundland remains trapped under a northerly flow, allowing the generation of clouds, fog and drizzle. This northerly flow is also generating some clouds in parts of the eastern Maritime provinces, thanks in part to cool sea-surface temperatures in the Northumberland Strait, Gulf of St. Lawrence and around Newfoundland.
The high is otherwise bringing brighter conditions to the rest of our region, but we do have a bit of unsettled weather to deal with midweek.
A cold front extending from a low-pressure system will move from Hudson Bay into northern Labrador, connecting with a separate area
of low-pressure that will exit the Great Lakes and move south of Nova Scotia.
This will move a line of rain showers from west to east across the Maritimes and Labrador Wednesday and Wednesday night, moving eastward across Newfoundland on Thursday with a lingering chance of showers in the eastern Maritimes.
Looking ahead to the weekend, high-pressure in northern Quebec will try to be in control for the Maritime provinces and should be strong enough to hold a system south, while stalled lowpressure off Newfoundland will likely bring clouds and precipitation.
Still, the trend for May is looking better than April.
There’s also potential for a big warm-up around this time next week.
