Much of September featured a drier...northwest flow regime which brought bouts of autumn air to the upper Mississippi River valley. There were two notable periods during the month...a significant cold snap during the middle of the month that sent temperatures 10 to 20 degrees below normal. Near the end of the month...a strong ridge of high pressure brought several days of very warm and almost Summer like weather to the region. Regular frequency of weather systems kept precipitation totals for the month just slightly below normal.
