CHAMPAIGN — Cooler weather in mid-April has caused Illinois soil temperatures to fall, according to Jennie Atkins, Water and Atmospheric Resources Monitoring (WARM) program manager at the Illinois State Water Survey. Soil temperatures at 4 inches under bare soil averaged 49 degrees on April 17, 5 degrees cooler than historically. For the first two weeks of the month, however, soils were warmer than normal. Warmer weather in the second week of April led to highs reaching the low to mid-70s. Cooler weather at the beginning of the third week caused temperatures at 4 inches under bare soil to fall 15 degrees by April 17 with lows in the 40s.
