Updated Long-Range and Snow Forecast Maps

1/28/2014, 10:07:51 AM

Fast-moving storm will impact the south coastal Maritimes very late Tuesday night/Wednesday then bring heavy accumulations to southeastern Newfoundland Wednesday/Wednesday night.

Based on latest surface observations over the southern U.S. and latest model guidance we have shifted the accumulating snow farther north in the Maritimes. Best chance of 15 cm or more would be over southern/eastern Cape Breton.


St. John's, NL.... 20-25 cm of snow with potential for slightly higher amounts over southern Avalon Peninsula Wednesday/Wednesday evening.

In the west, the combination of a weak Pacific storm system and incoming Arctic air will lead to a period of accumulating snow over the Canadian Rockies and into southwestern Alberta Wednesday and Wednesday night.


Overall, looks like a general 8-15 cm for the mountains of southeastern BC and extreme southwestern Alberta, while the Calgary area gets about 5-8 cm.


Long-range forecast model interpretation.

Potential for a messy storm from Ontario through southern/eastern Quebec and into New Brunswick starting Saturday in the west and getting into eastern areas Saturday night.

Computer models have trended farther north and a little stronger with the storm, which means greater potential for heavier precipitation with snow possibly going over to a mix for southern areas.

Regardless, this type of system will have a significant impact on travel across the region. I will have greater detail on this tomorrow.

There is also the potential for a significant winter storm for southeastern Canada around Feb. 5. Busy pattern for the meteorologists no doubt!

Looks like the worst of the cold will be concentrated over the Prairies for a good chunk of February. More of a normal cold farther to the east and also in the far west.

Farther ahead.......

So far, the long-range models still do not show any major, sustained warm-ups across Canada.
