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.

The monthly temperatures for February 2010 averaged about 2° warmer than the long term average. Precipitation (as water) was about average.

The snow depth at the end of February is 6 inches in Green Bay (weather service station)., 13 inches in Rhinelander (100 miles NW) and 18 inches at Laona (75 miles NNW)

Feb 27 The morning low temperature of 28° F was the warmest daily low temperature since November 30 (90 days).
Feb 26 The morning low temperature was a brisk 14° F, but the high temperature reached 37°.
Feb 24 There was light snow scattered since the 22nd, with a total of 5.6 inches of new snow.
Feb 23 There was snow this morning in Green Bay, and it was heavy for a short period, but it probably will not add much to our snow cover.

Chipmunks out and about, Oconto County, Pensaukee (Tom Erdman).

That is as early as we have seen here in recent years for chipmunks. The other early records are 02/21/1998 and 02/22/2004. For 16 years of data (1994 through 2010, lacking 2008) the mean date for first chipmunk sighting is March 9. This data is a little "soft" since several different locations were included, but there seems to be a high degree of similarity between various sites in any year so it is reasonably accurate.

This is the 4th consecutive day for which the high temperature rose above 32° F and there is a slight feel of early spring. The nights were quite cold however with lows of 24, 19, 13 and 18.

Feb 19 Two consecutive warmer days, with highs of 38° and 37° F (our first above freezing this month) have been most welcome. The familiar calls of Northern Cardinals have increased significantly in Green Bay.
Feb 17 The high temperature of 38° F in Green Bay resulted in some melting and just the faintest spring-like feeling that I have noticed. Another 2-3 weeks should bring a welcome, transition of the season. Prior to today, Green Bay has only been above 32° on 6 days of the last 64 (since Dec. 14), and each of those days was above freezing for only a few hours.
Feb 12 There have been several wide-ranging and long-lasting storms in the U.S.A. of late, including deep into the southeastern U.S. and into the southern plains. Today the weather channel folks say that this morning there was at least a little snow on the ground in all 49 of the continental United States--a rare occurrence. Sadly, the winter Olympics are getting underway in British Columbia, Canada in the face of one of their warmest winters on record, with a severe shortage of snow on the ski slopes.
Feb 10 Northeastern Illinois recorded an earthquake this morning of magnitude 3.8 on the Richter scale. Few consequences have been reported.
Feb 9 Green Bay received 5.2 inches of new snow today, increasing our snow depth to about 9 inches.
Feb 2 Green Bay's snow depth has diminished to about 3 inches.
Feb 1

At the end of January 2010 (yesterday) Green Bay had received 26.2 inches of snowfall for the winter, compared to 62.5 inches at the same date last year.
