The effects of a recent -AO/NAO has shown it’s full effects on the north-central US. A clipper-like system marking the leading edge of the first arctic air mass of the season has brought record snow to Minneapolis.
Officially 7.9 inches of snow fell at the Airport, the most snow for this early in the season and not far from the record biggest October snowfall of 8.2 inches recorded in 1991.
The 7.9 inch snowfall broke the previous record for earliest 4″+ by 9 days, set all the way back in 1905.
It’s only the 10th time where the Twin Cities has recorded an inch or more of snow before Oct 21.
