Unseasonable October Bilzzard Strikes I-90

It may be the time for autumn leaves to turn their lovely orange color, but that is not the case in a large swath of South Dakota. A snow blizzard stretching from the small South Dakota town of Wall (population 766) all the way to the Wyoming border covers as much as 150 miles of interstate I-90.

The blizzards and snowfall aren’t only striking South Dakota. They have been dumping snow across multiple portions of Montana all the way to what is termed as the “lee” of the Rocky Mountains in Colorado which is a reference to the clearing or meadows just ahead of the mountain range.

The snows are moving eastward and will be dumping heavily on Wyoming and South Dakota with what are called “snow drifts”. For travelers unfamiliar with these snow drifts, they are coming in at 40 to 60 mph. At those speeds, it is not possible for salt to be tossed on the highways. The drifts will literally pile up snow on the roads making them difficult to impossible to traverse.

As the snows stretch across Oklahoma to Wisconsin, the warmer weather will convert them to heavy rain storms. The rains are expected to start this evening.
