Sudden Stratospheric Warming - Close @ Hand

Defined as a complete disruption / reversal of the polar vortex @ 60°N... a well-forecast MAJOR stratospheric warming appears close-at-hand.

The vortex has bifrucated @ 10 mb on JAN 24...30 mb on JAN 27...and is poised to reach 50 mb level in a few days.

The event gets a quick mention in WSI/s latest winter update...

""An incipient stratospheric warming event, which appears to be historic in magnitude, may continue to favor more Arctic air masses in mid-latitudes and increases confidence in the widespread cold forecast of the US these upcoming few months.""
