An unusually low snowfall would be defined as a value more than two standard deviations below the mean. The mean is 41 cm, and the standard deviation is 5.3 cm. Calculating two standard deviations below the mean gives 41 - 2(5.3) = 41 - 10.6 = 30.4 cm. Among the provided options, 25.1 cm is the only value significantly lower than this threshold, making it unusually low.
