Perhaps it was that my Mom grew up in mid-northern Canada (where it rarely got above 65 F in the summer). Perhaps it's that her Mom was born and raised in mid-northern Canada.
Perhaps it's the other side of the family who has told multiple stories of driving through blizzards in the Utah/Idaho/Montana/North Dakota area where the interstates are closed (but they still keep driving).
I'm just not intimidated by the frigid temperatures and/or forecasts of snow.
Don't get me wrong, seven feet of snow is a big deal, and I would definitely be intimidated into cancelling events/plans for a six/seven feet of snow blizzard.
But given all this above history, a forecast of 1- 5 inches of snow and/or frigid temperatures is not going to keep me at home. Just sayin'.
Everyone is different of course, and some people like staying inside and warm (curling up with a good book, movie, etc.) I suppose this is where my extrovert side shines through.
