Drought in Logan, Illinois

Due to a multi-month precipitation deficit dating back to the Fall of 2025, Severe (D2) Drought was ongoing at the start of the month. The official observation for Lincoln measured 1.13 inches of precipitation during the month of January, which was 1.04 inches below normal. The continued below normal precipitation resulted in Severe Drought persisting through the month.

For the sixth consecutive month, much of the region experienced below normal precipitation, with deficits of 1 to 2 inches common during the month of January. Mean temperatures were above normal for much of autumn, but below normal during December and January. While precipitation was below normal for the month, a disturbance brought almost an inch of rainfall west of I-55, which led to modest improvement in the drought conditions. Elsewhere, the ongoing drought expanded across central and eastern Illinois. Streamflows, lake levels, and regional water tables remained well below normal.
