After several winter storms swept across the country in January 2023,
snow blanketed most of the continental United States by January 26. The
the Moderate Resolution Imaging Spectroradiometer (MODIS) on board
NASA’s Aqua satellite acquired a sweeping false color image of the
scene on that same day.

In this type of image, both infrared and visible light (bands 7,2,1)
are combined to help differentiate snow from cloud. Snow shows up as
bright blue, while most clouds appear white. Cold clouds that contain
ice may also be tinted with a touch of bright blue. Vegetation looks
electric green, water deep blue, and unvegetated land appears tan or
brown.

In this image, snow reaches as far south as Arizona, New Mexico, and
Texas west of the Mississippi River. Every state east of the
Mississippi also wears at least a partial cover of either snow or
cloud.

The most recent storm travelled across the Southwest, the Southern
Plains, the Midwest, and the Northeast United States from January
23-26. Reports from Arizona measured more than a foot of snow in the
high elevations in the north and center of that state. By January 25, a
substantial dump of heavy, wet snow accompanied by winds gusting to 20
mph (32 km/h) caused widespread power outages. In south and central
Missouri, more than 75,000 lost power. That region also accumulated up
to 8 inches of fresh show.
