2020-2021 Winter Outlook for Southeast Michigan
Status of ENSO
Weather Forecast Office
Detroit, MI
La Ni?a is ongoing heading into
this winter with cool anomalies noted
in the sea surface temperature in the
central and eastern equatorial Pacific
(see first page of this PDF). The typical
coupled atmospheric processes have
been observed as well.
The Climate Prediction Center
gives high likelihood for La Ni?a to
continue through the winter and into
spring 2021. Read more about the La
Ni?a Advisory and the latest forecast
from CPC here (updated weekly).

Typical La Ni?a Impacts
Weather Forecast Office
Detroit, MI
As a result, La Ni?a will be a key driver
for the wintertime atmospheric circulation
pattern, with implications on the local
conditions for the Great Lakes. In the
"typical" La Ni?a wintertime setup,
blocking high pressure develops over the
northern Pacific Ocean which sets up a
ridge over the eastern Pacific and western
United States. Downstream of this, a
longwave troughing pattern is typically
favored over the eastern US. This would
point to a more active winter for the Great
Lakes with the jet stream helping to direct
numerous storm systems through the
region.

La Ni?a Composites
Weather Forecast Office
Detroit, MI
Composites of historical La Ni?a winters (that
also account for climate trends in recent decades)
show that approximately 50 to 60% of them had
higher than normal precipitation across SE Michigan
and about 40 to 50% of them saw higher than
normal snowfall. Signal is not particularly strong for
either above or below normal temperatures for La
Ni?a winters, but recent data do suggest a warming
trend regardless of ENSO state.
These composites show us what has occurred
most often in the past, but are not enough to predict
how this specific winter will unfold. Our sample of
past La Ni?as is relatively small and there are other
climate processes that are not accounted for.
