A Winter Weather Advisory has been issued for Monday night into Tuesday morning for the Missouri Bootheel, far southern Illinois, and most of western Kentucky. In the Winter Weather Advisory, mixed precipitation is forecast, including up to one inch of snow and sleet accumulation and a light glaze of icing. Main impacts will be slippery roads, bridges, and sidewalks and other untreated surfaces. Travel impacts are possible or likely to occur during the Tuesday morning commute. Further north in the rest of southern Illinois and southwest Indiana, a brief period of light snow is expected Monday night. Across Trigg, Christian, and Todd County, KY, temperatures will be above freezing, and most of the precipitation will fall as rain. There is still time for adjustments to the forecast, and additional counties may need to be included in the Winter Weather Advisory. Details will be finalized Monday morning.
