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.

Feb 25 The snow storm delivered 1.3 inches of snow yesterday and 9.1 inches today for a total of 11.1 inches of snow to the Green Bay area, and snow is predicted to continue into tomorrow. The snow is wet and dense and difficult to shovel.

First Crocus blooming of the 2007 season today in the mix of sun and clouds. The bulbs are at least 3 feet from the side of the house, naturalized in the lawn in a southern exposure, City of Green Bay near UW-Green Bay (David Parsons).

Here's a graph of Green Bay temperatures for January 1 through yesterday. Note the period of 23 days for which Green Bay's temperature did not rise above freezing . Low temperatures have been below freezing since January 5th -- 48 days and counting.

Oaks typically keep the dead leaves of the last growing season through the winter, as in this individual of Quercus ellipsoidalis (Hill's oak) on UWGB.

If you look closely there are always interesting things to see. Here's a photo of lichens on UWGB yesterday. This particular type of lichens are sometimes called "British Soldiers", the bright red portion reminding some of the British uniforms of the American revolution era.

Warm weather continues with a high temperature of 48° F in Green Bay. Snow is rapidly mealting on UWGB's Cofrin Arboretum.

At the end of the day the snowcover had decline conspicuously--the lawn outside of MAC Hall was free of snow over most of its area.

This is the end of the mid-winter continuous snow period in Green Bay. There is still widespread snow, but there are now significant areas of exposed earth on level areas away from buildings. The starting date was January 15th, so the length of continuous snow cover this winter was only 51 days. Keep in mind that we almost always get significant snowstorms in March, so this does not mark the end of snow. [Also, there was snow cover beginning on Dec 1 (1.1 inches) and Dec 4 (0.9 inches), but most of the snow melted by Dec 8th and by Dec 12 our area was essentially snow-free until January 15th. ]

Feb 19

There is a definite warming trend in Green Bay. Today's high temperature of 41° F is the first time we have been above freezing since January 26, and that high of 33 is the only exception going back to January 12th.

A couple of early indicators that spring is just around the corner:
A muskrat out and about in Bellevue, Brown County (Kate Hutton).

A muskrat out and about, Oconto County, Pensaukee (Tom Erdman). Also Canada Geese appearing in that area for the first time, looking for summer quarters.

Feb 14 Green Bay is about 20.5 inches below the avearge snowfall for the winter. There is about 2-4 inches snow cover in Green Bay and snow banks along roads are remarkably small.
Feb 12 Ravens aerial courtship maneuvers are conspicuous, Oconto County, Pensaukee (Tom Erdman). Also Cardinals very vocal in the area and House Finches on UWGB campus are checking out nest sites in the conifers near MAC Hall on UWGB.
Feb 11 Today's high temperature of 23° F is the highest temperature so far in the month of February.
Feb 10 Today is the 9th consecutive day that the temperature in Green Bay fell below 0° F,
Feb 07 Green Bay's low temperature was only -6° F this morning--a warming trend after four very cold days. Green Bay has not been above freezing since January 12th, except for one brief reading of 33° F on January 26th. There is not much snow though. I think we are about 16 inches below average snowfall for the winter.
Feb 06

Cold weather continues with a low of -14° F, though the daytime temperature rose to a lofty 8°.

Green Bay is ice-covered as far north as I can see from the south end.

Feb 05 The low temperature was -13° F in Green Bay and it was still -13 at 9:00 a.m. Virtually all schools in the area are closed today, because of moderate winds and dangerous "chill factors".
Feb 04

The cold northern air mass continues to drop down over our area, with a morning low temperature of -12 in Green Bay. Even more remarkable, the high temperature for the day was -2° F!

Feb 03

Green Bay's low temperature was -10° F, our coldest temperature of the winter to date.

An immature, female Sharp-shinned Hawk was found frozen to death, exactly as shown in the photo.  Temperature reached -16 F, with a wind chill past  -25 F. Many animals and birds perish at this time of year.  We seldom have a chance to find them. Oconto County, Town of Pensaukee (Tom Erdman).
