1992 Snow Weather Wise

If you were living in Montana in the summer of 1992, this is one weather event you’ll never forget. The August 22-23, 1992 Montana snowstorm was a rare, extreme weather event that caused major agriculture damage, and is a reminder of the lore of Montana weather. Almost 34 years ago, an early-season Arctic front moved south along the Continental Divide. While snow was forecasted for the mountains above 6,500 feet, the cold air was unusually deep and strong, resulting in accumulating snow down in the lower elevations. To have a few flakes of snow in August in the lower elevations is not all that unprecedented, but this snow stacked up and accumulated on unfrozen ground. Cut Bank and Browning had the first accumulation of about 2″ on August 22nd. Glacier Park had more than a foot. The cold air and snow then spread south and east. 8-10″ of snow fell in Great Falls, shattering the August record for snow. Helena had about 6″ in town, with up to a foot in the higher terrain. Even Butte, America picked up 5″. And instead of melting the next day, cold air stuck around for a week, preserving the snow. Record cold hit with lows in the 20s and 30s. The heavy snow, combined with freezing temperatures created devastating impacts on crops and the shortest growing season ever for large parts of Montana. This unusual and extreme weather event is an example of how wild Montana’s weather can be at any point in the year. I’m meteorologist Curtis Grevenitz and now you’re a little more Weatherwise.
