Yesterday’s Winter Storm Watch has become a Winter Weather Advisory for much of the Northern Plains as well as southern MN. The National Weather Service is forecasting 2-4 inches of snow by Monday evening for much of the southern part of the state. It may seem a little early for snow, but it is Minnesota, so how unusual is this October snow?
Well, a little more unusual than you may think.
According to the State Climatology Office, the last time the Twin Cities received snow in October was 2002 (Oct 20-21, to be specific). The Halloween blizzard of 1991 set the record for most snow in October at 8.2 inches. However, as the climatology office notes, snow in the first half of October is pretty rare.
The last time it snowed in the first half of the month was 1992, when the Twin Cities received 0.3 inches of snow. The most snow ever recorded before October 16 was 2.5 inches on October 10, 1977. In all, the Minneapolis/St. Paul metropolis has experienced snow between October 1st and 15th just eight times in the last 60 years. Tomorrow will almost certainly mark the 9th such occasion, and they may come close to that record of 2.5 inches before the end of the day.
