I'm glad we have these questions to choose from, because it's really difficult to choose. I love all snowstorms, in-and-out of season. But if I HAD to pick....
A snowstorm in winter or something out of season? If it's the latter, early or late? WINTER.
Wet snow, dry/fluffy snow, or something in between? DRY, SPARKLY POWDER THAT STILL CAKES GOOD TO TREES
Light/calm winds, or windy conditions while it's snowing? LIGHT WINDS
Continuous snow, or do lulls not matter as long as amounts end up as expected? CONTINUOUS
12" in 12 hours, or 18" occurring over 36 hours? 18" IN 36 HOURS ( February 1, 2015 is a good example. Took about 25 hours to get our 17" of snow. But at the end of the day, you're walking in 17" of snow not 12").
Bitter temperatures, or just cold enough to stick well during the storm? BITTER COLD
Storms on holidays/your birthday/some other meaningful day, or are dates irrelevant? DATE IS IRRELEVANT (but of course Christmas Eve would be orgasmic)
If living in a lake effect area, would you rather have a synoptic or lake effect storm of the same amount? SYNOPTIC (only based on the statement "of the same amount")
