We Just had a major snow storm in MTL Quebec this Saturday.
My girlfriend and I were watching people outside slipping and sliding all over the place and laughing, when all of a sudden there was this awsome
thunder crash and a lightning bolt. Ive never seen anything like this before and was wondering if this is normal. Could this be because of global
warming? As a kid Ive always wondered why there was never any thunder or lightning during snow storms, but I guess there is
i don't have a definite answer. still i grew up in minnesota, where i lived the first 21 years of my life. i have NO memory of ever seeing thunder or
lightning in the winter during snow storms and blizzards. not a single one. i do remember being told by my father when i was really young that it
never happened. his knowledge of the weather is like mine, primarily informed through experience.
i think it is an intriguing question, i think i will have to look around for an answer.
I saw lightening in a very heavy snowstorm in Indiana in about 1989 or 1990. The snowstorm had HUGE flakes (probably the size of quarters or bigger).
I saw a bright flash that I first had mistaken for a transformer blowing. After the thunder hit, it was obviously lightening.
It's kind of unnerving the first time you see/hear it, because it's so rare. It's just NOT supposed to lightening during a snowstorm!
I was shoveling off a roof in Harrisburg, Pa with my room mate, and we almost got scared off the roof by a nearby lightning strike and accompanying
thunderclap. This was during a heavy sustained snow- almost 2 m. of snow already laying. This was early '96, there was a bridge knocked down by
this storm. Only time I've ever seen that, mostly you just see snow with the sun shining brightly and consider that some kind of anomoly.
I live in upstate NY. We see thunder snow once or twice a year. It usually happens in late fall or early spring when there are drastic changes in
temperature (70 degrees F to 20 degrees F in 24 hours) and significant moisture in the air.
