UNDATED -- Many trees in central Minnesota are clinging to their leaves despite fall-like temperatures for weeks.

University of Minnesota Arboretum Woody Plants Specialist Jeffrey Johnson says it is a bit unusual for this time of year. But, Johnson says it's likely because the overnight temperatures haven't been cold enough.  He says there are other factors that can figure in like how wet or dry conditions are, but he says once we see a hard freeze the leaves should come down.

Johnson says with colder temps on the way and maybe even some snow, he thinks most of the leaves will come down in the next week or so.
