A series of disturbances traveling along a slow-moving frontal boundary to the west of Southeast Michigan brought repeated rounds of rainfall to the region over a 48 hour period. As the main low pressure system moved northeastward from the Central Plains to the Upper Peninsula of Michigan on Tuesday, February 20, a record high axis of moisture advected across Southeast Michigan. Record warmth accompanying the moisture axis caused the snow pack to melt as repeated rounds of rain brought two to three inches of rain from Monday, February 19 through Wednesday, February 21.
