WaPo has an interactive map:
Cue the 2019 Fall Foliage Prediction Map on SmokyMountains.com, a site promoting tourism in that region. The interactive tool is one of the most helpful resources to reference as you plan your autumnal adventures.
“We believe this interactive tool will enable travelers to take more meaningful fall vacations, capture beautiful fall photos and enjoy the natural beauty of autumn,” data scientist and SmokyMountains.com chief technology officer Wes Melton said in a statement.
Travelers are presented with a map of the United States and a user-friendly timeline to adjust below. As you drag through the season, the map changes to show where fall foliage is minimal, patchy, partial, near peak, peak and past peak.
By swiping through, you can easily find the best time to visit the region of your choosing.
Enjoy. According to the map, Chicago's peak occurs between October 19th and November 2nd. You might see some color this weekend in the Michigan Upper Peninsula and the top tier of New England.
