A shift in the weather this week is bringing with it a delicious sign of early spring: maple-syrup season.

The production of maple syrup is dependent on that special, short-lived period of above-freezing days and below-freezing nights that usually hits Michigan in March.

According to a Facebook post by the U.S. National Weather Service in Gaylord, maple tree sap flows best with highs in the 40s and lows in the 20s, with a little extra help on sunny days that warm the roots and sides of trees to get sap flowing as well.

Michigan ranks in the top 10 states for maple syrup production in the U.S., according to the Michigan Maple Syrup Association.

Michigan Maple Syrup Weekends will be held across the state throughout the month, when many maple syrup makers will open their doors for live demonstrations and other fun.

A list of dates and participating maple syrup makers can be found online via the Michigan Maple Syrup Association.
