GOLDEN VALLEY, Minn. - A frigid Monday morning in northern Minnesota will likely have a big impact on the fall colors.

Morning temperatures Monday in northern Minnesota fell into the hard freeze category, which means the thermometer dropped to 28 degrees. It's an important threshold for leaves and fall color.

DNR Forest Health Specialist Jana Albers says leaves at the very top of the tree exposed to the cold will likely die and turn brown. The temperatures will also accelerate color development in the tree's lower leaves, with more yellow developing rather than the reds or purples.

Her report from the Grand Rapids area is that most trees are still green with some yellows and reds starting to appear, which is slightly behind peak season schedule.

Typical peak for the metro is still a couple weeks away.
