After a brief respite, the snowy February resumed, as the sixth heavy snow of February 2019 broke a slew of weather records across the state.
A surface low pressure system, supported by very strong winds aloft, tracked from Texas into the Upper Mississippi River Valley on Wednesday February 20th. The main ingredients working in favor of heavy snowfall production were 1) cold air already in place, and 2) a strong surge of moisture from the Gulf of Mexico. As the moisture surged into the region ahead of the low pressure system, heavy snow developed rapidly, advancing from south to north within a period of about 18 hours.
The snow began in southern Minnesota around midnight, reaching Twin Cities and St. Cloud between 3 and 5 AM, Brainerd by 6 AM, and Duluth and northeastern Minnesota after 8 AM. The snow became heavy very quickly, with dozens of reports of visibility reduced to 1/4 mile or less during the day.
The entire state saw accumulating snows, with totals greater than 6 inches across the southeastern half of the state, and also extending along the shore of Lake Superior. A swath of 8-10 inches, with some higher totals, extended from the southwest corner of Minnesota, through Marshall, Mankato, and the Twin Cities. Totals observed around the state included a high mark of 14.6 inches at New Ulm, 10.9 inches at Bird Island, 9.1 inches at the Twin Cities International Airport, and 6.8 inches at Silver Bay.
The storm solidified this as the snowiest February on record at many stations across Minnesota (and additional snows after this one only added to the new records). Four of Minnesota's five "first-order" weather stations broke February snowfall records. Interestingly, the storm itself had stiff competition from major winter storms on February 20th of 2011 and 2014, and as a result did not break many daily snowfall records for the date.
