Finally...Winter's first storm of the season arrives.
An upper level storm system will strengthen as it tracks across the region today, producing accumulating snow, a stout wind and slowly falling temperatures.
Snow is expected to begin prior to sunrise west of the Illinois River and spread east, reaching the Indiana-border by noontime. The snow will continue into tonight, with accumulations ranging from an inch or two south of I-70 to 3 to 5 inches near the Kankakee River.In addition to the falling snow, a west to northwest wind of 20 to 30 mph will gust in excess of 40 mph at times, creating blowing and drifting snow.
Of concern, snow initially falling on unfrozen ground could cause initial melting forming a thin layer of ice before the snow begins to accumulate.
