Cool days set to moderate

Cold conditions continued across Iowa with most areas losing degree days equivalent to a bit over one day in southern Iowa to nearly three days in the northern part of the state. Remember that early May is typically cooler than the rest of the season, so normal degree day accumulations per day will nearly double by late June. That is why we have to be careful in converting degree days to calendar days, because we constantly change the definition of normal.

Moderating temperatures the next couple weeks can kick crop development into gear. Moisture is favorable for crop development in most parts of Iowa, for now.
