The coldest weather of the season, so far, is set to arrive this weekend and last into next week. This would be about the time of year for the coldest seven day period to occur as shown by the featured chart. The top chart displays the seven day period each year with the coldest average temperature. The bottom chart displays the frequency of a given day participating in that coldest period. January certainly dominates this metric with only the first portion of February having similar frequencies.
