Atlantic: Weekend 'weather bomb' to bring heavy snow, strong winds

Thursday, January 30th 2020, 7:42 pm - Parts of Nova Scotia could see 20-40+ cm of snow, while parts of Newfoundland will see the strongest winds, possibly exceeding 100 km/h. This storm also comes in time for Groundhog Day, which could impact Sunday's event at Shubenacadie Wildlife Park.

Though temperatures recover for Friday and Saturday, a powerful 'weather bomb' is set to reach the Maritimes Saturday evening and Newfoundland by early Sunday, bringing snow and strong winds for Nova Scotia and the island, though with a switchover to rain for the latter. What we know so far, below.

FRIDAY INTO SATURDAY: CALMER SKIES, SLIGHT TEMPERATURE RECOVERY

Though Thursday featured a quick burst of snow for parts of Nova Scotia and bitter wind chills, Friday looks a lot calmer, with temperatures recovering somewhat across the region, even creeping slightly above zero for parts of Nova Scotia.

Saturday will be similarly warm mild, but by the evening, the effects of a powerful nor'easter will begin to make themselves felt.

WATCH BELOW: WHAT WE KNOW ABOUT THE STORM'S PATH

The snowfall begins in the late afternoon or early evening for southwestern Nova Scotia, spreading across most of the province by the late evening. Most of the Maritimes' snowfall looks to be confined to that province, though New Brunswick's southeastern corner may see some snow as well, with Moncton about on the cusp of 5-10 cm.

Thanks to those above-zero temperatures hanging on for a bit, there's the chance of a brief period of rain/snow mix for the southern shores of Nova Scotia.

But the snowfall will intensify through the evening and continue through the overnight. Winds will also pick up as well, with particularly strong gusts near the coasts.

SUNDAY: THE STORM IMPACTS NEWFOUNDLAND IN EARNEST

The system will begin to spread snow across Newfoundland pre-dawn Sunday, while easing across the Maritimes.

The snow won't be as heavy there as in the Maritimes, but eastern parts of the island could certainly pick up some significant accumulations.

ATL snow

By Sunday afternoon, milder air reaches the Burin and Avalon peninsulas, allowing for a transition from snow to rain. Precipitation eases through the overnight period.

Though the winds will be easing for the Maritimes, they'll pick up in Newfoundland through Sunday, with the strongest gusts likely reaching the 80-100+ km/h range.

This storm is likely to qualify as a 'weather bomb,' undergoing a drop in pressure of at least 24 millibars in 24 hours, which typically manifests as very strong winds.

Beyond, forecasters predict an active and messy pattern for the mid to late week.
