A winter storm system is currently affecting the entire area. Moderate to sometimes heavy snow has already affected south-central Indiana and portions of north-central Kentucky. This moderate to heavy snow will continue to spread into central and south-central Kentucky. The system will quickly push eastward tonight with snow expected to come to an end by midnight.
All snow is expected except maybe across the far southeast portion of the outlook area where temperatures at or just above freezing could lead to a wintry mix instead. WIth the heaviest snow across the north, It is expected that 4 to 6 inches of snow accumulation will be possible in southern Indiana and 3 to 5 inches across the northern half of Kentucky. As a result, a Winter Storm Warning continues for all areas north of the Western Kentucky and Bluegrass Parkways. Areas south of the warning are expected to receive 1 to 4 inches of snow; thus, a Winter Weather Advisory is still in effect for south-central Kentucky.
After the snow departs this evening, temperatures will plummet by dawn, bottoming out in the upper single digits in southern Indiana and the lower to middle teens in central Kentucky. Northwest winds of 10 to 20 mph will drop wind chills below zero in southern Indiana and into the single digits in Kentucky by sunrise Friday.
