Low Pressure System Bring Snow, Rain to North Central U.S.

This true-color image from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard the NOAA/NASA Suomi NPP satellite shows a large low pressure system centered over the northern plains and Upper Midwest on November 28, 2016.

The National Weather Service reports that this system will bring potentially heavy snow to the Dakotas into this evening (11/29) before gradually tapering off overnight. Scattered snow and some rain showers will still be possible across the northern plains and Upper Midwest into Wednesday (11/30).

True-color images like these are created by combining data from three of VIIRS's 22 channels--namely those sensitive to green, red, and blue wavelengths of light--along with supplemental data from other channels. True-color imagery can be used in a variety of applications, including monitoring amounts of snow and ice, demarcating the boundaries between warm and cold air masses, and tracking smoke from wildfires.
