Well the big one is finally here. The snow started at about 2:30 and began coming down hard for the last two hours. However it's currently not snowing at 4:30. The wind is still coming out of the south east and its bringing warmer moisture rich air with it. the radar maps is indicating the line between snow and sleet is approaching quickly indicating that warm air is almost here and the precipitation will switch shortly.
Theres only about an inch or so of snow and that will probably melt in the next few hours. overall this storm system is quite large and its gaining strenght as the warm air from the south and the moist air to the north swirl together the surface map shows how the wind is interacting with this front. The majority of the precipitation associated with this storm is rain, much of it is south of us where the center of the storm seems to be concentrated. I would say the forecast from yesterday missed the mark. it's not much of a winter storm, and the snow accumulations are not that significant. its become more of an early spring rain shower for Illinois than any thing else. the warm air from the south pushed pretty far north causing this to turn into rain.
