"Lake Effect" -- what is that exactly? Here's an explanation of this impacting phenomenon along with a photo from today that captured how sharply different weather can be in & near lake effect snow. The Gary-Hammond area saw 6+" of snow today thanks to lake effect. #INwx #ILwx pic.twitter.com/pfhSSK5E4D

Higher intense snow will begin focusing across NW IN this AM, in particularly, Lake Co. IN. Expect moderate, to periodically heavy, snow for a good portion of this AM across this location. Visibility under the heaviest snow will fall to around one half mile at times. #inwx pic.twitter.com/E7ttK1Szrd

This live @INDOTNorthwest webcam image from I-80/I-94 not far east of the IL/IN state line stresses how impacting heavy lake effect snow can be.

Trends are ideal for temperatures to drop rapidly tonight across much of the area, apart from near Lake MI and in the heart of the Chicago metro. Temperatures will likely drop below 0° by early-mid evening w/ wind chills 10° to 20° below. Bundle up. #ILwx #INwx
