| Description |
NASA image captured December 7, 2010 NASA's Terra satellite captures daily visible and infrared images around the Earth and took a daytime image of a blanket of snow in the Upper Midwest this week. Even though astronomical winter is less than two weeks away, the central and eastern U.S. are already experiencing meteorological winter. Meteorological winter is basically an identification of the winter season based on "sensible weather patterns" for record keeping purposes. That means "meteorological winter" happens whenever snow and ice occur, even before astronomical winter arrives on December 21, 2010. Astronomical winter is based on the position of the Earth in its orbit around the sun. The residents of the upper Midwest are already feeling the effects of winter this week, with high temperatures in the 20s and 30s, and wind chills in the single numbers (Fahrenheit) or colder. Today's satellite image of snow on the ground in the upper Midwest is proof of an early meteorological winter. It was captured by the Moderate Resolution Imaging Spectroradiometer or MODIS instrument on December 7, 2010 at 17:05 UTC (12:05 EST). MODIS is an instrument that flies aboard NASA's Aqua and Terra satellites. On Saturday, December 4, a low pressure area moved through the Tennessee Valley and generated snowfall from eastern Iowa and Minnesota east through Wisconsin, northern Illinois, Indiana and through the Ohio Valley. The MODIS image shows snow on the ground in eastern Minnesota and Iowa, southwestern Wisconsin, northern Illinois, much of Indiana, northern Kentucky and western Ohio. The snow extends farther east, but that area was out of path of the Terra satellite as it captured this image. What it does show, though, is that winter conditions have arrived before astronomical winter did. Residents in these areas of the U.S. hope it leaves early, too.
