It has been a quiet winter for Chicago in terms of snow, but that could all change this weekend.
The National Weather Service on Friday issued a Winter Storm Watch for the Chicago metro area starting Saturday evening through Sunday evening.
The alert warns of the potential for snowtotals possibly in excess of 6 inches.
Weather models currently show an average of 4 to 8 inches of accumulation on the ground by Sunday night, but these totals may change again due to the complexity of the system. If the models do not change, this will be the biggest snowstorm of the season.
Conditions will be quiet between Friday and Saturday afternoon, but the snow is expected to begin falling Saturday evening with light accumulation. Snowfall will likely become moderate to heavy overnight and into Sunday morning before easing off in the afternoon.
The system will move through the Chicago area by Sunday night, but lake effect snow could continue to fall into Monday morning with little accumulation.
The weather will clear up during the day Monday, but the temperature will drop to a high of 15 degrees.
Warmer weather is expected to return Tuesday with highs in 20s and another chance for snow.
