THURSDAY: WARNINGS ISSUED AHEAD OF POTENT WINTER STORM
A deepening low-pressure system brought its first flakes to Nova Scotia Wednesday night as it began passing south of the Maritimes, accompanied by slowly rising winds. Snow was set to fall through the night into Thursday.
Though southern and central New Brunswick and Prince Edward Island will definitely see some amounts from this system, it's Nova Scotia that will bear the brunt, with some 15-30 cm possible for much of the province through Thursday.
Across the Gulf of St. Lawrence, much of Newfoundland is also set to see some significant snow, beginning in the pre-dawn hours of Thursday morning.
Snowfall warnings are in effect for all of Nova Scotia and much of Newfoundland.
With the temperature differential being what it is, the Avalon Peninsula can expect some of the lowest snowfall amounts through the day Thursday, and will even see periods of sometimes heavy showers.
Steep drops in pressure in systems such as these often portend strong winds, and they will be stiff over much of the region as the system passes.
Newfoundland in particular will have a blustery day, with gusts of 70-100 km/h expected for St. John’s by Thursday evening as the system exits the region.
LOOK AHEAD: ANOTHER WINDY, RAINY SYSTEM AWAITS
Looking ahead further, the next system will bring widespread wind and rain this weekend with near record warmth for Sunday. However, temperatures turn colder in behind it early next week, but it will turn warmer again late week.
