Diurnal Temperature Variation & The Northwoods Snowstorm
Late this past week our mild temps took a dive back to seasonal. It was getting out of hand as our overnight minimum temperatures hovered around our average maximum temperatures. The cooler temperatures boost our chances for our first measurable snowfall to take place soon. The average date for OSNW3's first accumulating snowfall is Nov 20. That said, a trend that continues here at OSNW3 for the month of November is the lack of precipitation.
