Winter Storm Juno: The Most Spectacular Weather Imagery We Saw | The ...

Winter Storm Juno dumped snow measured in feet over New England and unleashed destructive coastal flooding in parts of coastal Massachusetts.

If you're a weather geek, or simply enjoy looking at cool images, Juno provided its fair share of spectacular weather images that made our hearts pump. Scroll down and enjoy.

Perhaps the best view of all was from the International Space Station (above), as NASA astronaut Terry W. Virts tweeted early in the morning of Jan. 28, 2015.

The city lights of the I-95 Northeast corridor stand out, with Washington D.C. and Baltimore at the lower left and Boston toward the top center of the image. Also note the milkier texture to the city lights of the New York City, Long Island, Hartford, Providence and Boston metro areas, due to a veil of lingering clouds from Juno.

Virts later tweeted another view from just off Cape Cod.

Our friends at the University of Wisconsin's Space Science and Engineering Center's CIMSS Satellite Blog captured this infrared satellite loop from Jan. 26-27, 2015 showing Winter Storm Juno's intensification off the East Coast.

The image above is a high-resolution visible image from the Suomi NPP polar-orbiting satellite when Winter Storm Juno was still in its organzing stages along the East Coast.

Note the cloud streets extending off the Georgia coast, indicative of cold air streaming offshore behind the cold front. You can also see washboard texture to the clouds over parts of the Southeast U.S. Moist, stable air was forced over the southern Appalachians triggering these wave clouds.

We showed a similar image from the International Space Station earlier. This one from the Suomi NPP polar orbiter is a wide view of Juno taken during the pre-dawn hours of Jan. 27.

The comma-head appearance is classic and the contrast with the dark land and ocean is breathtaking. Some of those clouds offshore (as well as wrapping into southern New England) were actually producing lightning.

By the morning of Jan. 27, the central pressure of Winter Storm Juno had dropped to at least 975 millibars, according to analysis from the National Weather Service's Weather Prediction Center.

The gif at left from earth.nullschool.net illustrated the storm's impressive wind field.

Wind gusts up to 78 mph were clocked on Nantucket, Island.

Blizzard conditions were reported for 14 consecutive hours in Marshfield, Massachusetts.

Blizzard conditions were also satisfieldat Boston's Logan Airport, Worcester, Massachusetts, Providence, Rhode Island, Portland, Maine and Augusta, Maine.

The persistently strong winds triggered major coastal flooding along the Massachusetts shore, from the north shore to Cape Cod and Nantucket Island.

This image was a model forecast for sustained winds from Juno around sunrise on Jan. 27.

We had to clip part of that image to fit the article, but at that time, the model was forecasting winds near or exceeding 50 knots (darkest red shading) from the mouth of the Bay of Fundy (between New Brunswick and Nova Scotia) to a few hundred miles east of the New Jersey shore.

The small patch of blue (lighter winds) almost due south of Cape Cod was where the model forecast the center of Juno to be located at that time.

In the close-up visible satellite image above, we stare into the center of Juno, denoted by the clear path off Cape Cod.

While intense, some more intense extratropical cyclones off the East Coast of the U.S. can sometimes exhibit eye-like features similar to tropical cyclones.

While the 30-inch snow total in eastern Long Island was certainly eye-catching, we were most amazed by the gradient in snowfall across the nation's most populous metro area.

Long Island MacArthur Airport in Islip is only about 51 miles driving distance to Central Park in New York City. Yet it was a difference of 15 inches of snowfall. Just across the Hudson River, parts of Bergen County, New Jersey picked up only 3-4 inches of snow.

Air traffic was unusually light over the busy Northeast corridor on Jan. 27, as you can see in the screen grab above from Flightradar24.com. Almost 8,000 flights had been canceledahead of the storm.

Essentially, what you're seeing is a satellite that can diagnose precipitation rates. The animation above resembles a radar view of Juno over the ocean. The Global Precipitation Measurement (GPM) mission offers the goal of sampling precipitation worldwide, something land-based radar networks cannot do.

Finally, let's end with a spectacular satellite view of the snow cover from Juno, once again from the Suomi NPP satellite.
