Weekly Long-Range Update

February 25, 2014; 9:47 AM ET

Snowfall forecast Tuesday night through Wednesday evening

Two weak systems will cross eastern Canada Tuesday night through Wednesday night and will bring intermittent, light snow to most areas. Amounts over Quebec and New Brunswick will be generally less than 3 cm for most.

Expect slightly higher amounts over eastern Nova Scotia later Wednesday and Wednesday night and on the order of 2-8 cm. However, as the storm intensifies over the Atlantic Wednesday night and early Thursday, there is the potential for over 10 cm over southeastern Newfoundland.

These clipper-like systems will just reinforce the cold air into eastern Canada as we go through the week.

Temperatures well below normal second half of this week

No real major storms over most of southern Canada the rest of this week as the northwest flow dominates, but there will be some weaker systems with lighter snows.


Long-range update through March

This is my latest interpretation of the weekly ECMWF and CFSv2 long-range forecast models...

Confidence is higher than normal for temperatures with pretty good agreement between the models. However, confidence is lower than normal for precipitation as there is greater disagreement.

There are signs that the core of the winter cold may be finally retreating to the north around March 20 as temperatures climb back to normal over the Prairies and East.
