The episode as NWS OAX wrote it up.
Heavy snow moved into northeast Nebraska Monday morning 1/29/01 and continued until a little past midnight Tuesday morning. The snow was preceded by a period of freezing drizzle. Although additional snow moved back into northeast Nebraska Tuesday afternoon...most of the accumulations occurred Monday. However, the wind picked up late Monday night and continued through Tuesday afternoon causing considerable blowing and drifting snow. Most schools were closed Tuesday and Wednesday, and the blowing snow closed many country roads at least one lane to many east to west highways in northeast Nebraska. Heavier snow amounts included, 12 to 14 inches at Bloomfield, 11 inches at Laurel, 10 inches at Loretto and Cedar Rapids, 9 inches in West Point, 8 inches at Neligh, Osmond, Madison and Albion and 6 inches at Norfolk. When combined with northwest winds of 30 to 45 mph...drifts of 5 to 7 feet were relatively common by Wednesday morning.
