At least you got out Dave
Ya you better polish up the equipment and charge up the battery, put it in the padded carrying case and stick it away until spring. The 5cm of snow is the end-never will it melt-done for-finished-zippo dejecting in 2020.
I'm looking a 5cm of snow, ground temps from a 15C day followed by a 5C Sat. will warm the earths nicely. The rate of snow falling will melt at a rate of 1.45 flakes per 3 flakes falling. Now I'm going out on a limb for this and thinking the 10C with rain next Friday will finish off this white display.
To top it off the 14day forecast shows mainly above temps.
I'm going to say my hand warmers,-50C Baffin boots, toque, insulated coveralls, will be well used into December while I get a hunt or two in.
On the upside you get to try out those winter tires.
