Winter '20 / '21 - Temperature and Precipitation Characteristics for CONUS During La Niña Winters Since 1950

No surprise ... all cool ENSO winters are not created equal.
Some are weak or moderate or strong.
Some associated with QBO-East and some with QBO-West.

During the analysis period between 1950 and 2012 ... most La Niña winters occurred with QBO-E.
Of the winters depicted below ... 15 of the 21 (~71%) were QBO-E.

QBO for winter '20 / '21 will be west.
Probably a moderate La Niña through mid-winter.
