Fall colors are being delayed by recent warmth

- Do you think the fall colors are a little late this year?  Well, you’re probably right.  While the overall variation of when trees turn those gorgeous fall colors is pretty small, this year, the recent warmth is likely playing a role in why many trees are still green.  The northern half of the state typically starts peaking this time of year, but according to the MN DNR, much of northern Minnesota is only experiencing 20 to 40% color… well behind what is considered normal.  The metro area is currently experiencing even less color with generally just 15 to 25% of trees changing to their fall shade.  So what do the trees need to start producing those colors?  With the ground well moistened from a pretty normal year for rainfall, the trees need sunny and pleasant afternoons with cool crisp mornings.  If you want to put actual temperatures to it, you want highs in the 50’s and 60’s and lows ranging from the mid 30’s to the mid 40’s.  This is the best communication device to trees to tell them to start changing color.  Here is a peek at the fall colors across the area this weekend.
