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.

Unseasonably warm weather returns for one day. Green Bay's high temperature was 72° F. The record high for today is 77 and the average high is 51.

Oct 17 Several tree species are still in bright fall color while the trembling aspen in the foreground has already lost many of its leaves. In the background many of the oaks are still green. Baird Creek Park, Brown County, WI.

The ground is snow-covered and snow continues to fall, Vilas County (Kathy Groves).

Green Bay is still snow-free, but we are promised a hard freeze tonight with temperatures well down into the 20's. This morning's low temperature was 29° F.

The drought continues in Brown County. UWGB's prairie pond is nearly dry. Leaf color is less striking than in most years. On the Cofrin Arboretum only staghorn sumac and Virginia creeper are particularly bright so far. The leaves of Fraxinus pennsylvanica (green ash), have turned brown and fallen with very little of the usual yellow fall leaf color.
