MINNEAPOLIS (WCCO) — Minnesota is seeing a brief glimpse of winter-like conditions Friday, with snowflakes falling hard in some areas.
Some areas, like St. Augusta, reported a half an inch of snow accumulation on the grass Friday morning. A somewhat unusual sight in mid-October.
So, what causes these conditions?
According to meteorologist Mike Augustyniak, it has to do with the way air is moving upward, causing perfect conditions for a certain type of snowflake, called dendrites, to form. Here’s his explanation.
At least twice a day @NWSTwinCities (and other @NOAA sites) launches a weather balloon to sample the temperature, humidity, & wind vertical profile. Today's weather balloon shows the -12 to -16 temperature layer is right where lift is centered; dendrites form at those temps pic.twitter.com/aOB7wH2pVv
