Growth

The village meadows are flourishing in all this rain, the grass is waist high.. Absence of sunshine doesn't stop stuff growing or even ripening: Consider the rainforest, there is plenty of wet but not much light at ground level, yet things still grow.

It's the same with agricultural crops apparently. Even if there is no prolonged sunny spell the wheat crop will still ripen. 

The problems come later, because the seed heads will be swollen and will have a high moisture content. This makes the plant top heavy. At this point the crop is in danger of laying down and becoming unharvestable.

Furthermore farmers need the land to be dry to allow the monster harvesters to operate. This year, only time will tell.
