January Precipitation Highlights:

• An active storm track through the central U.S. brought much above normal precipitation to central and southeast IL this month.  Monthly totals were 3-4" in many areas, which was 1-2" above normal.  As far as snowfall was concerned, totals ranged from 6-8" south of I-70, to 15-20" northwest of I-55.  This resulted in near to slightly above normal snowfall for eastern IL, and amounts as much as 1 foot above normal for parts of central and western IL.  Peoria set their 5th snowiest January with 17.9", while Lincoln was 2nd snowiest with 19.1".
   
• The most significant snowstorm of the month occurred on the 11th-13th.  This system brought amounts in excess of 8 inches along and west of a Bloomington to Shelbyville line, and greater than 12 inches from just west of Lincoln and Springfield westward to the Mississippi River.  Another strong system on the 19th produced 2-6" snowfall accumulations north of I-72, along with 30-40 mph wind gusts.  Farther south, rain totals exceeded a half inch south of I-70.
   

January Temperature Highlights:

• January saw a roller coaster ride in temperatures, starting out with much above normal readings for the first 8 days the month, and ending the month with record cold.  The result was monthly average temperatures near normal south of I-72, and 1-3 degree below normal readings farther north.  Extreme cold affected the region on the 29th-31st, when numerous daily record low temperatures and record cold high temperatures were set.  Blustery winds accompanied the arctic air, with wind chills dropping as low as -53 F in Bloomington on the morning of the 30th.  This was the lowest wind chill ever observed at Bloomington.  Much of central to western IL spent 30-40 consecutive hours below zero during the heart of the cold.
