As many people know, it can snow just about anytime in Montana – as the August 1992 storm demonstrated.

To be fair, most July and August snow falls at higher elevations in Glacier National Park, but in August 1992, even a good chunk of Montana got in on the action.

Some parts of Great Falls and the surrounding areas received as much as 8.3 inches of snow during what the National Weather Service called an “unprecedented” weather event.

The NWS explained that an early-season arctic surface airmass moved south along the Continental Divide, resulting in record cold temperatures across Montana for several days leading up to the snowfall.

The NWS said that it was a “significant event, considering no snow had ever been measured in August at Great Falls in 100 years of record keeping.”

By the morning of August 22, two inches of snow was reported in Cut Bank and Browning.

By the next afternoon, 8.3 inches of snow had fallen in Great Falls.

In addition to the snow, the temperatures were definitely not normal, either. The NWS says that during an eight-day span of August 1992, the temperature reached or fell below 34 degrees five times.
