Observations by Gary Fewless for Green Bay WI (Lat.N 44.51° Long. W 88.02° ), except as noted. For flowers lacking conspicuous petals or sepals I define "anthesis" as release of pollen by mature anthers.

Dec 31

After the snow storm of Dec 28 and 29, cold air moved in with a low of 10° F on the 30th, and 0° F today.

Dec 28 Green Bay received 4.6 inches of snow before midnight today and another 2.5 inches after midnight, for a storm total of 7.1 inches.

Dec 25 Green Bay received another 1.4 inches of snow yesterday. The NWS station at Green Bay reports snow depth at 7 inches on Dec 25.
Dec 22 Green Bay's low temperature this morning was 7° F, our lowest temperature of the winter so far.

path in snow New snow on the trail at the edge of the prairie.
Dec 20 A strong winter storm ("Breanna") arrived in Wisconsin. Green Bay received 9.7 inches of very wet, heavy snow. Snowfall amounts varied widely, with the most reported at about 20 inches in Dane County. High winds followed the snow, but the snow was too wet to blow much in Brown County, and the snow compacted to a modest level on the ground.
Dec 16 Green Bay's high temperature was 43° F again today.
Dec 15
High temperautre of 43° today and fog. The photo is of the Highway I-43 bridge at the mouth of the Fox River, Green Bay, WI, photographed from the Green Bay shoreline at UWGB.

Green Bay Shore Dec 14, 2012 The most extensive ice-cover on Green Bay so far this winter, shown here from the UWGB shoreline.
Fox River Mouth Numerous waterfowl at the mouth of the Fox River, the largest numbers being Mallards (photo) and Ring-billed Gulls.

The Mississippi River water level is reportedly near its all-time low. That will have big implications for transport on the river.

Lake Michigan is about 17 inches below its level on this date last year, and is now tied with the lowest level ever recorded (576.2 feet, in 1964).

Dec 13

A warming trend has begun in NE Wisconsin. Yesterday's high temperature was 40° F and the temperature did not fall below freezing overnight. Indeed the temperature rose during the evening and was still 38° at midnight. The recent snowfall is rapidly melting and although short-mown lawns are still white, old fields are more brown than white now.

Ice-cover melted off on the East River in Allouez overnight.

new snow These two photos show the prairie on Dec 8 before the Dec. 9 snow storm, and then again on Dec 10 after the snow.
snow in old field The temperature was warm enough to make the snow stick to the plants, as here in this old field.
Dec 9
snow Snow began in Green Bay about 9:30 a.m. and by noon it looked like this near the East River. The Green Bay weather station at the airport reported 3.7 inches before midnight today and an additional 0.4 inches after midnight on Dec 10. Light snow continued until about 5:00 a.m. on the 10th.
Dec 5
Green Bay shore Along the Green Bay shore, there is new ice this morning that formed since I looked last evening at about 4:30 p.m. Also compare the water level to yesterday's photo of approximately the same view. Lake Michigan's level rises and falls each day, somewhat similar to the tide on the Ocean, though the causes are different.
  The U.S. Army Corps of Engineers data indicates that the water level in Lake Michigan at the end of November was about 16 inches below its level last year at this time. That is the lowest level for the month of November in recorded history (since 1860’s). If the forecasted level through the winter is even close to correct, a new all-time record water level will be reached.
prairie pond ice New Ice formed on Prairie Pond overnight.

Warm weather continues. Note the green grass at an entrance to UW-Green Bay's Cofrin Arboretum. And growing moss in a nearby swamp.
Green Bay shore Also, the water level in Green Bay is very low and approaching the all-time record low.
Dec 3 Green Bay's high temperature today was 62° F which tied the record high temperature for this date, previously set in 1998. And the daily average of 52° was 26° above "normal" for this date and also tied the rocord. Local rivers and ponds are ice-free and so are the waters of Green Bay.
Dec 2 The preliminary count of whitetail deer taken in the recent gun deer season of Nov 2012, reports a total of 243,739.
Dec 1
Green Bay begins the month with no snow cover and very mild temperatures. The high temperature today was 49° F and the daily average temperature of 43° is 16° F above "normal".
