Spring is in the air. But mud is on the ground, and will be for a while.

Mud season is an annual mucky rite of passage in the lives of northern New Englanders. This year, it's gloppier than usual in parts of the region, and hanging around longer.

Mud season sets in when snow smelts, ground softens and spring rains come. Parts of Maine, New Hampshire and Vermont had a snowier winter than usual, followed by a wetter-than-average spring, making for a muddier mess.

Mud season is normally over by April, but forecasters say it could stick around until early May.
