(4:00PM - 12/13/18) A storm system moving through the region will bring rain to much of the state over the coming days. The potential exists for heavier rain across portions of Central and Southern Illinois, which could lead to minor flooding.
A broken area of rain has developed and pushed northward across portions of Central and Southern Illinois this afternoon. Periods of rain of varying intensity will be possible across much of the state from now through Saturday night. The only area that looks to miss out on the rain is Northwest Illinois.
Rainfall amounts will be light for much of Northern and Central Illinois, with less than 0.75" expected. Further south, heavier rainfall totals of 1-2" are likely, with locally higher amounts possible. Higher rainfall totals across this area may led to some minor flooding.
