Green Bay's high temperature was 47° F ("normal" high for this time of year is about 25°) and accelerated the melting of snow. In spite of the addition of 2.7 inches of snow in the previous 4 days, Green Bay's snow depth is still only 3 inches as of this morning (reduced to 0 inches by the next morning).

The monthly average temperature for January 2012 was 7.1 degrees above "normal". Total precipitation (includes water equivalent of snow) was 1.4 inches, which is 0.27 below average. That amount included 10.7 inches of snow. Last year we had 19.1 iches of snow and the average temperature was 1.7° below average.

The weather has been relatively warm for this time of year (high in the 30's F). Snow is melting and there are puddles in parking lots and streets. It feels more like early March than January. There has even been some fog, as here along the UW-Green Bay shoreline. Green Bay has had 8 inches of snow in January, but the standing snow depth is about 2 inches. bayshore

We have had a modest number of Canada Geese as year-round residents in the Green Bay area as long as I can remember, but it seems to me that there are more this winter. Certainly they are more active in my area that in recent years. geese

Jan 22 Warmer in GB with a high temperature of 35° F and a little light rain at around the freezing mark, making for some periods of very slippery roads. A portion of Highway I43 was closed due to the icy conditions.

Jan 18

Green Bay's low temperature was -2° F this morning and the temperature has risen only to 11° at noon. Our coldest day of the winter to dater. Rhinelander reported -15°.

Although a few other dates have registered colder low temperatures, A case can be made that the coldest day in Green Bay history occurred on Jan 18, 1994 when the low temperature was -28° F and the high temperature was -18° F!!. Another candidate is Jan 21, 1888 when GB reached a low of -36° F, but the high reached a balmy -8° F, yielding a slightly higher daily average temperature.
