29. Autumn colors are starting with cool nights and warm days. Days are getting shorter, but maybe Indian Summer before Astronomical Fall.
Temperatures began rebounding after Saturday morning's frost. Sunday still found some morning clouds, but they moved out allowing sunny skies and light breezes in the afternoon. The picture below I pulled off the Fall Color Report from TravelWisconsin.com. It was taken near Rhinelander by Russell B the 1st of October 2005. These leaves look like they are either Northern Red Oak or Northern Pin Oak, I'm not good enough to tell by just the photograph. Sunday's numbers:
Temps: 41.6 / 68.3 Dewpoint: from 35 up to 50 Barometer: slowing falling from 30.30 to 30.00 "Hg Windgust: 10 mph NW at 12:40
A low pressure was organizing in the plains, the warm front was moving towards the Upper Midwest, spreading clouds out ahead of the boundary that even produced some scattered light showers. This is the source of the 'less than 0.01"' in the blog's headline.
Temps: 49.1 / 68.8 Dewpoint: rising again from 48 to 62 Barometer: continued falling from 30.00 to 29.75 "Hg Windgust: 11 mph SE at 14:10 Rain: trace
This picture I found on Flickr.com. It seems to be taken from outside Madison, but I didn't easily find the owner listed.
