Grand Rapids' total snowfall for the season is running about a foot below average, but we could make up some of that deficit as a strong low pressure system sets its sights on West Michigan.

Forecast models during the past week have been consistent with a developing low in the Great Plains into the day Thursday, April 6. As the forecast period creeps closer, details have started to snap into focus.

A winter storm watch will go into effect Thursday -- stay tuned to how the forecast could change as it gets closer.

Initially, some of the less reliable models were hinting at snowfall totals in the double digits for some areas. That's now looking less likely. Models are still in disagreement about how much snow is expected. We still are looking for a few inches of accumulation by Friday morning, however.

Several weather models are outputting snow accumulations on Thursday and Thursday night, but as to how much remains up for debate. 

April snow isn't uncommon in Michigan. Just last year, a record-breaking 5.4" of snow fell on April 8 in Grand Rapids.

By this time, Grand Rapids should be at 73.5 inches of snow -- we're only at 59.7 inches.
