Preliminary Climate Summary for November 2019
November continued the
trend of October with mean monthly temperatures that ranged from 2 to 4 degrees
F cooler than normal. The first two
weeks were near record cold, while during the last two weeks of the month
temperatures moderated with greater cloud cover. Extremes for the month were 55°F at Windom
(Cottonwood County) on the 21st and -21°F at Isabella (Lake County)
on the 12th.
Precipitation for the
month was mixed, with some areas wetter than normal, many areas drier than
normal, and some climate stations were close to normal for monthly
amounts. Over 2.25 inches fell in
portions of Olmsted, Winona, Houston, Faribault, and Mower Counties. Austin topped the list with 2.63 inches. Many parts of western Minnesota were drier
than normal with Wheaton (Traverse County) reporting less than a tenth of an
inch for the month. Yet more
precipitation, perhaps 0.5 to 1.0 inches is expected before the end of the
month.
Major snow storms
occurred over the 21st, as well as the 26th and 27th. Portions of Cook, Lake, and St Louis Counties
reported over 15 inches, topped by nearly 27 inches at Isabella (Lake County)
up on the highlands of the north shore of Lake Superior. Long-term climate stations that reported
record snowfalls on the 21st included: Cass Lake with 4.5”, Tower
with 7.0”, Waskish with 5.0”, Gunflint Lake with 8.0”, and 4.6” at
Embarrass. Some other stations reported
over 9 inches on the 21st.
For the 27th some of the
following long-term climate stations reported record amounts: Kimball 8.5”, Cambridge, Faribault, and Wells
8.0”, Jordan 7.8”, MSP 7.2”, Owatonna and Moose Lake 7.0”, Windom 6.8”, and
Winnebago 6.5”.

Wet Year Update;
As we continue to see
excess precipitation fall in many areas of Minnesota, more long-term climate
stations have already reported their wettest year of record. Some of these include:
Rochester (Olmsted
County) 53.51”
Owatonna (Steele County)
51.46”
Faribault (Rice County)
48.40”
Zumbrota (Goodhue
County) 46.30”
Winona Dam (Winona
County) 44.31”
Marshall (Lyon County)
43.38”
MSP Airport (Hennepin
County) 40.89”

Minneota (Lyon County)
39.62”
Artichoke Lake (Big
Stone County) 35.60”
Browns Valley (Traverse
County) 35.37”
I am sure yet more
annual precipitation records will fall in Minnesota as we go through the month
of December 2019.

Past Weather Features:
The
two coldest November 29ths in state history were in 1875 and 1896. In 1875 no temperatures above zero degrees F
were reported, even daily highs. Morning
lows were in the minus 20s and minus 30s F. This same pattern repeated on
November 29, 1896 with many climate stations reporting morning lows in the
minus 20s F and minus 30s F. The daytime
high only reached -15°F at Crookston and Roseau.
A
slow-moving winter storm delivered 8 to 16 inches of snowfall to many parts of
the state over November 29-30, 1991. It
proved to be the snowiest November in state history, with many areas receiving
over 30 inches for the month.
By
far the warmest November 29th occurred in 1998, with nearly half of
the state reporting daytime highs in the 60s F under sunny skies. Many golf courses were open for golfers to
test the fairways and greens.
