A line of severe storms is expected to develop along a strong cold front and move across central and southeastern IL this afternoon into evening. Widespread wind damage and a few embedded tornadoes will be the main hazards.
Rain will switch over to snow behind the system tonight with the highest accumulating snow amounts near and west of the IL River. Very strong winds gusting over 45 mph will result in blowing and drifting snow, reducing visibility to 1/4 mile or less. Impacts to the Monday morning commute are expected.
South-southwest winds shifting to the west-northwest tonight. Sustained winds between 25 to 35 mph with gusts up to 55 mph expected. Gusty winds will blow around unsecured objects and create difficult travel. Tree limbs could be blown down and a few power outages may result.
