Winter Storm of December 15-16, 2007

Storm total snowfall from Dec. 15-16, 2007

A major winter storm affected the central and northeastern United States during the weekend of December 15-16.  Heavy snow fell in a large swath from the central Plains, northeast across the mid-Mississippi Valley and Great Lakes region, into New England.  Across Illinois, snowfall totals in excess of 6 inches were common roughly along and just east of the I-55 corridor from the St. Louis area northeast to Chicago.  The heaviest snowfall in this area fell from around Kankakee eastward into northern Indiana, with several totals over 10 inches, however localized snow totals around 9 inches were also reported in portions of central Illinois, around Decatur, Pana, and south of Jacksonville.

On the image above (click to enlarge), totals of 6 inches or more are shown by the green shades, with totals of 9 inches or higher in the darkening orange shades.  West of the Illinois River, totals of 3 to 5 inches were common (blue and purple shades).  In southeast Illinois, except around Effingham, totals of 2 to 4 inches were also reported, because the precipitation turned over to rain for a time.

 

This precipitation was associated with a strengthening low pressure system which moved from the lower Mississippi River Valley into the Ohio Valley.  A vigorous upper level storm system also moved  from Missouri into Illinois during the evening of the 15th, which enhanced snowfall rates and even caused a few periods of thundersnow east of I-55 and north of I-72.  The system moved into the lower Great Lakes by Sunday morning.

Storm total snowfall amounts:   These reports are considered preliminary and unofficial unless otherwise noted. Reports are thanks to observers in the COOP, SWOP, and COCORAHS networks, as well as county officials.
