Snow will increase in coverage this morning and end by early evening. Travel impacts are likely across much of the area today, especially across northwest Indiana, the southern Chicago metro, and points south. Intermittent heavier bands of snow are possible south of Interstate 80 and also across Lake and Porter Counties where Lake Michigan may contribute. Lake effect snow that is. The worst conditions are expected between mid-morning and mid-afternoon across the area. If travelling, be prepared for intermittent heavy snow, slush and snow covered roads, and visibility which may fall below a mile. Snow will end for most areas before the evening, but some light drifting snow tonight may keep icy or snow covered conditions in place, especially for areas with higher snow totals. I would stay in and make sure there are plenty of cookies for Santa.
