Lots of rain, freezing rain and ice pellets have been recorded so far this year in Southeast New Brunswick but snow has been somewhat scarce – until today.
A Colorado Low made its way across the continent this week bringing lots of snow to the American Midwest, Southern Ontario and Southern Quebec before arriving in the Maritimes.
Greater Moncton received 26 cm of snow followed by ice pellets and some freezing rain/drizzle along with strong winds which created poor visibility.
Snowfall amounts were fairly consistent across most of Nova Scotia with 22 cm at Greenwood and Halifax Stanfield Airport, 21 cm in Sydney but only 11 cm in Yarmouth.
Environment Canada says cold weather will replace the snow for late week with a brief warmup and rain expected this weekend.
While other parts of New Brunswick have already had significant snow this fall, the first snowfall warning of the season has been issued for Greater Moncton and the Southeast region.
Fresh from impacting Southern Ontario, Southern Quebec and the U.S. Northeast, Environment Canada says this storm will bring up to 15 cm of snow with ice pellets and rain mixing in before tapering off later tonight.
Schools were cancelled in anticipation of the storm with snow beginning to fall by midmorning.
Prince Edward Island and Cape Breton Island are expecting 15 to 20 cm with lesser amounts for mainland Nova Scotia.
A fast-moving cold front passed through the Maritimes today on its way to Newfoundland.
Powerful winds developed as a result which knocked out electricity to tens of thousands of customers across New Brunswick, Prince Edward Island and Nova Scotia.
The Greater Moncton International Airport recorded a gust of almost 90 km/h late this morning with Cape Breton Island reporting winds of more than 100 km/h.
Many locations across Newfoundland had hurricane-force gusts including Bonavista at 126 km/h, Wreckhouse at 107 km/h and St. John’s at 104 km/h.
The cold front also affected Southern Quebec yesterday with gusts of more than 80 km/h in Montreal and Quebec City.

Environment Canada has confirmed two powerful tornadoes ripped through west end Ottawa before touching down again in Gatineau across the Ottawa River.
Officials say dozens were hurt and at least two residents are in hospital with critical injuries.
Tens of thousands were left without power after at least 80 utility poles either snapped or were damaged.
Meteorologists say severe thunderstorms spawned one twister classified as an EF-3 with winds up to 265 km/h while another tornado was an EF-2 with winds up to 220 km/h.
Tornadoes are not uncommon in Southern Ontario but storms of this strength are rare.
