This marked the third consecutive month of above average temperatures. The NDMC index is a blend of science and subjectivity where intensity categories are based on six key indicators and numerous supplementary indicators. The Palmer Drought Index is used for assessing long-term meteorological conditions. As of late autumn, topsoil moisture was deficient in nearly all locations. Dry conditions extended throughout the rooting zone in the southwest, with near average to moist middle and lower soil layers elsewhere.
Stream flows in southwestern Minnesota are very low.
Red River flows are high relative to historical values for the date, however mid-winter Red River flows are typically insignificant at this time of year. Red River basin reservoirs have dropped from their unusually high levels in response to the dry autumn weather. The Corps of Engineers will maintain a flexible position in the drawdown of Minnesota River basin reservoirs, monitoring the ongoing dry spell. Many north central and northeastern areas are at or near all-time record low snow depths for this point in the winter. For some, three consecutive snow-deficient winters has led to economic hardship.
