||Here's the high
and low temperatures and average highs and lows for Nov and
Dec 2001. The low temperatures were above average every day from Nov
20 through Dec 29 (40 days).
|| Lower Green Bay is iced
over beyond the tip of Longtail Point (as
far as I can see from the mouth of the Fox River), except at the mouth
of the River.
Very little snow on
the ground. Not enough to cover all the grass in lawns from Green
Bay north to Wausaukee and only about 2 inches in extreme NW Marinette
Several people still reporting flocks of Robins
(wisbirdnet). Also 25-30 Bald Eagles on the Fox River (where the
water remains open at rapids in the Kaukauna area).
WIDNR is still advising
snowmobilers and others to stay off all northern lakes, because
generally the ice is not yet safe. Some smaller lakes and
bays and shorelines have 5-6 inches of ice, but ...caution is recommended.
Snow cover is virtually absent in southern
WI and light in northern WI except for the snow belt near Lake Superior
which has several feet.
About 1000-2000 Blackbirds

temperature in Green Bay has been above average for
the last 36 days, since November 20.
Although it seems like
a strong cold period the temperatures are close to seasonal. Yesterday's
low of 11F was the coldest temperature so far this winter
in Green Bay, but it is still 2 degrees above the average low for
40 Tundra Swans honking and flying over Waukesha
County today, and 112 were noted at the "metro pier" south
of Milwaukee (from wisbirdnet).

UWGB's Prairie Pond
or the Green
River froze in Allouez today (previously
reported for Dec 20, but it melted. It was open on the 23rd and
froze overnight). The table below contains the freeze date for this
site in recent years at the east end of Beaupre St. This is the
date that it is completely frozen and stays frozen until spring
(sometimes it melts and refreezes several times before this state
is reached). It may freeze slightly later farther downstream. Notice
that the date has ranged over 42 days (from Nov 12 to Dec 24) in
these 11 years. The average is about Dec 3.
First measurable snowfall
of the winter in Green Bay. The National
Weather Service reports 1.2 inches before midnight, and the snow
continued into the 24th.
look at fresh flowers, from this morning. Temperatures
are predicted to fall into the single digits in the next few days.
Several of the Christmas Bird Counts from Wisconsin
have reported Baltimore Orioles! Also a report of Ross's
Goose from the Madison area (Wisbirdnet). The cold weather approaching
should increase bird activity at feeders, where many people have
reported low numbers so far.
The East River opened
up (lost its full ice cover) at my observation point--stay tuned.
Many of the flowering plants noted earlier (see
Dec 15, 11 and 6) persist. Add "Bachelors Buttons" (Centaurea
cyanus) and "Pansies" (Viola tricolor) to the
list of horticultural species still in flower.

Numerous Canada Geese still present at Horicon
Marsh. A minimum of 5000 were seen in this area along Highway 151.
The numbers are probably much higher than that. The WIDNR reported
150,000 for Horicon in early November
A few snow flakes
in Green Bay, and a bit cooler, but still mild by Wisconsin standards.
Lawns (some at least) remain green and robust. There is no general
snowcover anywhere in Wisconsin and even northern lakes do not have
sufficient ice for ice fishing safely (WIDNR).
Interesting bird sightings continue, with another
report of a Cormorant, and Turkey Vultures at Devils
Lake. Also a sighting of Short-Eared Owls outside of Neenah
UWGB's Prairie Pond
froze again last night. If the ice stays now it will be more
than a month later than in recent years. The table below is updated
from Dec 7.

on the Fox River in Depere, Brown County (near GB).

Numerous reports of unusually late sightings
of birds in Wisconsin on Wisbirdnet (see http://enkidu.wharton.upenn.edu/%7Esiler/WISC.html
for recent notes or go to http://wso.uwgb.edu/wso/news.htm to sign
up for a mail list). Among the notable sightings are Yellow-rumped
Warbler in the Milwaukee area and a Palm Warbler in Rock
||Christmas bird counts reporting
many unusual species (more on this later). A Cormorant was
also sighted along the west shore of Green Bay in Oconto County, as
well as Tundra Swans and Sandhill Cranes (Tom Erdman) .
To the list of plants
still in flower (see Dec 6 and 11), five additional species
were added on Dec 15: Annual Bluegrass (Poa annua),
Gumweed (Grindelia squarrosa), Mayweed (Anthemis
cotula), Leafy-stemmed Plantain (Plantago psyllium
= P. indica ), Awl Aster (Aster pilosus), Evening
Lychnis (Lychnis alba). All were found along the Fox
River Trail in City of Green Bay. Five species found earlier could
not be relocated on 12/15: Aster simplex, Bidens cernua, B. frondosa,
Cornus stolonifera and Potentilla recta, although they
may still be flowering. All these species can be expected to continue
flowering until this mild weather ends. This brings to 37 the number
of species observed flowering outside of cultivation in the City
of Green Bay in December. Add Periwinkle (Vinca minor)
to the list of horticultural species still flowering .
A lone Double-crested
Cormorant was noted on the Fox River north of the Main Street
||The ice cover on UWGB's Prairie
Pond has begun melting. Only about 50 percent ice cover remains and
the forecast suggests it will all melt soon. My records are all for
the start of continuous ice, so this item remains open for this year
(see notes for Dec 7).
Warm weather has melted
most snow in the north and lake ice is entering the awkward
stage in which ice along the shorelines may be too thick for boating
and too thin to walk on. Snowmobile trails are virtually all closed
due to lack of snow.

yesterday in Door County.

Several people have informed me that Sandhill
Cranes are still present at several locations in Wisconsin,
including Green Bay's west shore in Oconto County, probably fairly
widely present yet. Also Tundra Swans are still present in
substantial numbers on Green Bay along with flocks of Robins,
Redwing Blackbirds, Grackles.
Two people have reported Chipmunks still
active in the City of Green Bay.

Warm weather continues.
Yesterday's high of 45 was 16 degrees F above the long term average.
The coldest temperature so far this Fall was 19 F on Dec 9, which
is still 4 degrees above the average low for that date. Sunny skies
and green grass today could easily pass for a day in October.
Of the 31 plants species noted in flower for Dec
2, most if not all are still flowering. We can add Pineapple
Weed (Matricaria matricarioides), seen today at UWGB.

not on the open water of Green Bay.
The warm weather has enabled a cover
crop of Oats (Avena sativa)to produce this
bright green growth on a fall savanna planting on UWGB's Cofrin
Arboretum. It was planted Oct 9 and the plan was for it to germinate
next Spring, but we didn't expect it to remain so warm this Fall.
It will be frozen eventually, but perhaps there is enough growth
already to prevent erosion and to discourage the early growth of
agricultural weeds next spring. The best laid plans...

Yesterday's high of

high was 20 and the low was 2.

average temperatures for the winter, but we are off to a warm start
for December. A high temperature of about 50 F is predicted

A flock of Tundra Swans was noted on Green

November 2001 was the
warmest November on record for Green Bay, Milwaukee and Madison.
For Green Bay the daily average temperature was 9 F above the long
term average and the high
temperature was only at or below the average on 2
days for the entire month. For 20 of the 30 days the daily low temperature
did not fall below freezing. We had 1.7 inches of precipitation
for the month which is 0.46 inches below average.
plant species listed in flower on Nov 22 and 23 were
still in flower along the Fox River Trail on Saturday morning, plus
the following species found by extending the bike ride a little
further into Depere: Nodding Beggar-ticks (Bidens cernua),
Common Beggar-ticks (Bidens frondosa), Small Peppergrass
(Lepidium densiflorum), Red Clover (Trifolium
pratense), Spotted Knapweed (Centaurea maculosa),
Brome Grass (Bromus inermis), Rough-fruited Cinquefoil
