QBO (quasi biennial oscillation):
In it's Westerly phase, the QBO is supportive of a stronger polar jet stream and increased snowfall totals for the NE. The result of a Westerly QBO is a stronger Winter time Polar Vortex, however this year, the Polar Vortex is showing signs of weakening, resulting in slower moving areas of low pressure. As a result, any snow systems that form may be very slow moving and dump large amounts of snow in relatively compact areas. Lake effect snow could be on the rise as a result.
The Central North, areas close to the border will see a higher chance of severe ice systems for winter 2016/2017. Due to the weak Atlantic Jet stream, which (a strong Atlantic jet) usually helps pull blizzards away from the US, this winter's jet stream is likely to be weaker due to low sunspot output.
This means, snow systems could hang around for some time, and give 1-2ft" at a time for states such as parts of PA & NY. For Florida & the South in general, a cool to near normal winter is expected with a higher rate of frost due to higher pressure, however above average precipitation is possible in the SE. For the SW, it is likely to be somewhat drier.
Thank you for tuning into our winter forecast, this shall be updated daily.
