2019 Ice-in was recorded as 12/6/19 @ 1:59 PM, 4 days earlier than average.

My 2020 Winter Ice-out calculations are figured as follows:

As of 2018, the average amount of elapsed days to ice-out after New Years Day is 110.458 days, which equates to an ice-out date of 4/20/20. (This is probably the best computation as it's based on the calendar.)

As of 2018, the average amount of ice days after the previous ice-in date is 131.292 days, which based on the ice-in date for 2019 (12/6/19) equates to an ice-out date of 4/15/20.

An absolute average of these dates would be 4/18/20 @ 3:59 AM. Science (and Al Gore) have nothing to do with this, it is merely numbers. When God decides on ice-out, it will happen, and the Cardinals will announce it via the Knottlane Sap Shack smoke. AOC and the left will then declare that the early or late date is due to climate change!

Average Days of ice , as of 2018 131.292

Average Ice-out Date is: April 20

Average Days of water, as of 2019 233.869

Average Ice-in Date is: December 10 

aLf, predicts 2020 ICE-OUT on 4/18/20 @ 3:59 AM (Leap Year corrected).

Ice dates are a consortium of Lake Lucerne Cardinals: Shirley Ratty, Meg, Andy, aLf - (Cardinal-Emeritus) and other Loons & Loonies.
In 2017, the Knottlane Cardinals were awarded the highly sought after Lake Lucerne loon pin of Excellence.

Thanks to The Knottlane Drone for keeping the gambling honest.
