A severe winter storm pummeled the Pacific Northwest in late January 2012, icing roads, downing power lines, and prompting avalanche warnings. On January 20, more than 250,000 customers were without electricity, as utility crews struggled to restore power, news sources said. Rising temperatures and potential new rainfall raised the possibility of flooding in the days that followed.

Snow still blanketed much of Washington State on January 23, 2012, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured these images. The top image is a natural-color scene similar to what our eyes would see from the sky. The bottom image is a false-color scene that better distinguishes between snow and clouds. Ice and snow are red. Liquid-water clouds are white, and ice clouds are peach. Vegetation is bright green.

Snow blankets the region east of Seattle and Portland, stretching all the way to the Idaho border. In the band of forest along the Pacific Coast, snow may be more prevalent than it appears, as it is sometimes hidden from satellite imagers by trees.

A dust storm blew through northern Texas in late January 2012. High winds and poor visibility made driving treacherous around Lubbock, and forced the cancellation of flights at the Dallas-Fort Worth airport, news sources said.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image on January 22, 2012. Dust plumes apparently arise from agricultural fields around Lubbock, and blow in a wide arc toward the northeast. Isolated red outlines indicate high surface temperatures associated with wildfires. The same high winds that stirred dust and canceled flights contributed to fire danger in the region, according to news reports.
