The area of low pressure that developed off Cape Cod late Wednesday didn’t take long to undergo rapid cyclogenesis and develop into a “weather bomb” off the Avalon.
Today, the system continues to track up along Newfoundland’s east coast with snow and very strong winds, causing blizzard-like conditions. The snow will let up as the day goes on, but we haven't seen the last of this system.
A blocking "Greenland High" won't allow the storm to track eastward, but instead will force it to retrograde – or roll back towards Anticosti Island in the Gulf of St Lawrence. Then, after spinning there until Monday, the system will eventually kick off to the east.
Over time, the storm will lose most of its energy, but the wrap-around winds will produce onshore snow squalls that will eventually add up. If you’re not a fan of the cold, this scenario has a silver lining - the arctic high that's being held west of us has been sitting there so long that the airmass had warmed up. We can expect slightly above seasonal temperatures next week.
