Satellite View of Snow Streaks from Tuesday's Snow Showers
The snow showers which affected the area Tuesday afternoon did not distribute snowfall evenly across the region. In fact, some areas saw more than an inch of snow from heavier snow showers, while other locations only received a trace or a dusting. This satellite image, from Wednesday March 13th, shows just how random the snow distribution was. Notice the bright white bands which run generally northwest-southeast across the Quad Cities area in western Ilinois, which represent locations that reported up to an inch of snow in yesterday's snow showers. While stratocumulus clouds cover much of central and eastern Illinois and northwest Indiana in this image, similar streaks are no doubt hidden beneath the clouds. A few isolated locations south and southeast of Chicago measured 1.5 to 2.5 inches of snow yesterday afternoon and evening, while other locations received only trace amounts of snow. Of course, the solid white areas of Iowa, Wisconsin and far northern Illinois show where more significant snow cover remains from earlier snows. River valleys can be seen clearly against the deeper snow pack in those areas.
These full-color satellite images come from the Space Science and Engineering Center at the University of Wisconsin in Madison. This particular view is from a polar-orbiting satellite nearly 440 miles above the earth, and provides an image once per day for our region.
