It’s F-Word Season! —– FROST
In 2019, Waterloo received its first sub-32* temperature of the season on October 12th.
In 2018, Waterloo it was October 14th before we had sub-freezing temps; and in 2017, it didn't occur until October 16th.
So, if those trends continue, we may have a few weeks remaining of the growing season.
Nearly all of Minnesota has either a Frost Advisory or Frost Warning already this month. (September 9th)
