My favorite season is fall. The air turns cool, there are hay rides and pumpkin patches, one curls up with a good book in front of a fire, reading scary tales, and, of course, watching the leaves change.

Japan has some very good, live updating of fall colors on a few websites.

The folks over at this website have a nifty little tool that predicts when fall colors will change this year. How do they predict the trends this year? With a little bit of data (and possibly a touch of pretentiousness):

The company uses a model that ingests a multitude of data sources including historical precipitation, NOAA precipitation forecasts, elevation, actual temperatures, temperature forecasts, and average daylight exposure to develop a baseline fall date for each county in the continental United States. Next, the model consumes hundreds-of-thousands of additional data points from a variety of government and non-government sources and layers this data over its own historical data from past years and, finally, with a high degree of accuracy, the algorithm produces nearly 50,000 date outputs indicating the progression of fall for every county in a graphical presentation that is easy to digest.
