Drought conditions that began in late June continued through the summer and into September.  Very warm and dry weather that began in the spring continued through the summer.  Temperatures remained well above normal into August, but began to temper during the latter portion of the month.  September began well above normal for the first week, but the fall transition began after that.  For the month of September, temperatures averaged fairly close to normal.  Rainfall was in short supply across the state.  Much of the state recorded less than 50% of normal rainfall for the month, with a few locations under 25% of normal.  The rapid deterioration of the corn and soybean crop that took place in July slowed as much of the damage had already occurred in July.  No significant damage occurred in September in spite of the dry conditions and early freeze of much of the state on the 23rd.  Harvest activities were more than 2 weeks ahead of normal.   Indications were that yields of the corn crop were around 140 bu/ac and 43.5 bu/ac for the bean crop.  These values were about 20% and 15% below normal for corn and beans respectively.  At the current price, the loss total was in excess of $2.6 billion.  As of 03 October, the USDA reported that Secretarial Primary Drought Designations had been listed for all 51 of the counties in the Des Moines CWA.  The drought conditions continued into October.
