Strong Wind in Lake, South Dakota

An occasional wind gust up to 50 mph was measured 6 miles south of Madison and 48 mph in Madison.

An area of low pressure intensified lifting northward across Minnesota into southwestern Ontario and resulted in very strong winds across southeast South Dakota. Some limited moisture wrapped back southward around the area of low pressure and produced a narrow band of light to briefly moderate snowfall during the overnight and early morning hours of November 20 with a small area between 1 and 3.5 inches accumulation. At times of falling snow, the very strong winds gusting from 40 to 65 mph produced some brief visibility less than one mile.
