SUMMARY: November was rather mild with a couple of cold snaps. The coldest weather occurred early in the month and again following a potent cold front on the 16th. The mildest temperatures were just ahead of a strong cold front on the 11th and again during the final week. The fronts on the 11th and 16th both kicked off thunderstorms, the latter with hail that covered the ground, and accounted for 75% of the month's total rainfall, which was near normal. Little snow fell, and the weather was relatively quiet, calm and dry after the 16th.
