NASA satellites, some of them positioned to monitor hurricanes and others involved in climate research, are watching the massive winter storm that has much of the Central and Eastern United States in its grips.
Everyday, these spacecraft help people plan their commutes to work as well as their recreational and professional activities.
As many as 100 million people will be affected by the frigid temperatures, rain, sleet and snow associated with what experts are calling one of the largest winter storms in the past half century.
More temperate conditions are forecast for the weekend.
People in the storm’s path may find solace in the annual Groundhog Day ritual involving Punxsatawney Phil, who emerged from his stump in Western Pennsylvania at dawn on Wednesday and failed to see his shadow.
That means an early Spring, according to folklore.
