| A slow-moving weather system produced widespread snow across the region late Friday night, January 11, and during the entire day and evening of Saturday, January 12. Snowfall rates in northern Illinois and northwest Indiana were light to moderate across most of the area, with some brief heavy snow observed south of I-80. Preliminary totals ranged from 2-4" for most locations north of I-80, to 5-9" south of I-80. This system was responsible for significant amounts of snow across Missouri and into central Illinois. |  |

| Satellite water vapor imagery from the morning of January 12 revealed the size of this system, with a large circulations from the Southern Plains through the Mid-Mississippi Valley. Embedded within this were several other strong circulations, all capable of steering deep moisture further northward and focusing forcing for moderate snowfall in northern Illinois and northwest Indiana. | Moisture was a key aspect of this system. This is a map of precipitable waters, or moisture through the depth of the lower atmosphere. These values were at to a little above one half inch in the NWS Chicago CWA (WFO Lincoln weather balloon launch measured 0.6" at 6 am and 6 pm). These values were over 130% of normal, which for a 12+ hour snow event is noteworthy. |
