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.
My thoughts the pattern into next week and a look at the weekly model output into early November.
Oho will likely bring hurricane-force wind gusts and heavy rainfall to parts of coastal BC Thursday night into Friday.
Weather pattern clues through the end of October.
Major rainfall event for the Maritimes late tonight, Wednesday and Wednesday night. Heaviest rain headed for central New Brunswick.
Flood potential for portions of the Maritimes midweek.
