FROM: Bob Weisman, Earth Sciences - St. Cloud State University DATE: 9 March 1999 SUBJECT: Record daily snow in St. Cloud Biggest March storm since 1985 Yesterday's snowfall was the largest March snowfall in 14 years. The total snowfall as of 6 AM this morning was 9 inches at the St. Cloud Airport and 9.5 inches at St. Cloud State University. Another inch is possible as the last gasp of this storm exits eastern Minnesota. There hasn't been a storm producing this much snowfall in St. Cloud during the past 26 months. The last major snowfall this large in central Minnesota was January 4-5, 1997, which produced 11.6 inches in St. Cloud with even higher totals to the west (for example: 27 inches in Wheaton, 21 inches in Alexandria). The last time there was this much snow in March was in 1985 when the storm of March 3-4 produced more than 17 inches of snow in St. Cloud. This particular storm, which dumped snow from Nebraska to Indiana and is doing it right now in the Mid-Atlantic states, was unusual in that the track of the storm (eastern Colorado to southern Missouri) was a good one for producing heavy snow in Iowa, but usually doesn't produce a lot of snow further to the north. However, this system also contained an inverted trough, a subject of currently funded National Science Foundation research at St. Cloud State University. Weisman, three current and former SCSU students, and colleagues from the regional National Weather Service offices have been studying this forecast problem for the past two years. A workshop on the findings was held last November in Sioux Falls, leading to improved techniques in the forecasting of such systems. While this particular storm did not quite fit the mold, the forecasts in the area were relatively close, showing that these techniques are, at least, a partial success.
