I somehow got the distinct impression you doubt my veracity.
You think I gave you a flippant answer. I wish. It has been snowing here since around 5:30 last night. Over 6 inches of new today, visability is down to about 150 yards, and still going strong. The forcast is for up to 15 inches last I heard. You may think I would pull your leg, Of course I would! Razzing greenhorns is one of our best forms of entertainment here!
But the old saw about 11 1/2 months of winter and 2 weeks of poor sledding isn't always that far off.
It started snowing this year on Labor Day, and pretty much hasn't stopped. Bozeman received around 10 inches on the ground last week.
Last year it snowed until June 1st.
We can get torrential rains and flash floods or if the snow melts too quickly the flooding is unbelievable. It doesn't spread out like floods further east because the mountains and foothills channel the water so you have these raging torrents of water tearing trees out of the ground, cutting channels across fields, through homes, It ain't pretty.
We get a lot of wind as well. The old joke about what do you call a log chain with one end nailed to a fencepost? A Livingston windgage. That joke is actually pretty true. When the end links start popping off the chain the wind is comming up a little.
60 mile an hour winds are considered a "Stiff Breeze" along the Yellowstone Valley. Sometimes the wind will really come up and push semi trucks over on the highway. They sometimes stay there until the wind dies down because you can't hold the trailers up in the wind.
The eastern end of the state can hit temps of 110+ in the summer, and the whole state can get chilly too. If a Siberian express hits, the temps can and have dropped to - 70. Metal freezes and becomes brittle at -40, and that happens just about every winter.
The Bitterroot, Seeley-Swan and Flathead are a lot more temperate, but they get SNOW. Lots of it at regular intervals.
This state is huge, bigger than some countries. The weather really varies between areas. It can be gorgeous, long summer evenings lasting until 10:00PM are my favorite.
But those days are not the norm. Long periods of grey skies and white fields are far more common than sunny days and green fields. Weather seen as extreme is pretty commonplace here. The only other place I have ever seen with our extremes is Alaska. Maybe Siberia, but I haven't spent any time there to compare.
If you are more specific, you can get answers that are specific to the area you are looking at.
Just a thought...
