FALL COLORS: Each fall, the trees in Wisconsin exchange their green leaves for reds, yellows, oranges, and browns. A lot goes on behind the scenes of this beautiful natural process.
Leaves get their green color from a pigment called chlorophyll, which is involved in the photosynthesis process through which trees produce their own food. With the shorter days photosynthesis stop and the leaves begin to die, this is when they change colors. Meteorologist Brittney Merlot explains what weather conditions come into play for creating vibrant fall foliage and lasting colors in the video above. Plus, details on the peak forecast and why certain trees leaves turn shades of yellow, orange and red.
