STORM SUMMARY 12-20&21-12
The first major storm of the season moved through the Midwest 20th and into the 21st. Rain actually began prior to midnight on the 19th. A low pressure system tracked from the southern plains to Chicago before heading up into Michigan during the evening hours on the 20th. The system produced 1-.2 inch rains over the area. Rain changed to snow 2-3pm in the Rockford area on the 20th and the changeover from rain to snow occurred between 4-6pm in Chicago. Areas around and north of I90 received the higher totals of snow as amounts to the south of I90 were generally under an inch. The combination of air and surface temperatures above freezing until after 12am on the 21st really limited accumulations on paved surfaces. Much of what accumulated south of I90 did so on grass and elevated surfaces. As temperatures lowered into the 20s by dawn on the 21st, salting was needed to prevent surfaces from icing up. Some plowing was needed in spots where 1-3 inches fell in the northern burbs.
