The planting, which usually takes place in late April, has already been delayed because of a colder-than-normal April. Temperatures in the region ranged between 4 and 8 degrees F below normal.
After the current system leaves the area, a second system will make its way to and stall over northeastern China.
Despite delaying the planting season, the rain is beneficial to the area, as the next several months usually don't yield substantial rainfall.
Following the second system, conditions should be drier and warmer.
