NASA tweeted this image of the East Coast blizzard as it developed over the Atlantic.
Although winter storms are not named officially like hurricanes, the Weather Channel has given this one a name: Nemo.
Today, though, is largely about weather predictors.
The National Weather Service is using the blizzard to test a system where it pulls in people's weather observations via Twitter.
"Everyone talks about the weather," the service noted on its Web page. "Now's your chance to "tweet" it and be heard. Through an experimental program, the National Weather Service will be searching for tweets that contain significant weather information."
To stay up-to-date on weather conditions in downtown Boston, IDG News Live has set up a Boston Blizzard Cam.
