Deep upper-level low pressure has pushed off the Mid-Atlantic coastline on Monday, April 22nd and it is spawning the formation of a coastal storm. This developing storm will impact the NYC metro region and New England with rain and perhaps even as far to the south and west as the Philly metro region.

Thanks to heavy rain and snow this winter season, many colorful flowers are blooming in California and they can be seen in this satellite image (March 20, 2019, courtesy Digital Globe, Capital Weather Gang twitter)
Incredible footage shows driver passing through 41 FEET of snow near Lake Tahoe in Sierra Nevada (March 10, 2019). A driver passing through a road near Lake Tahoe filmed the captivating scene as huge walls of snow were split in parts on either side of the road. Squaw Valley Alpine Meadows announced it will extend its ski season through July 7 this year due to record snowfall levels following a recent storm. Officials claimed the area had exceeded the 50-foot mark at Squaw Valley's upper mountain on Friday, while several other resorts have gone over 500 inches for the season.
Great Lakes ice cover extent has increased dramatically in recent days thanks to an intrusion of Arctic air. The ice cover content has increased to nearly 75% (as of March 3, 2019) and it is likely to increase further in coming days as the unusual cold spell continues.
A color enhanced image from GOES-16 on January 31, 2019 shows significant ice coverage over Lake Erie. Ice and snow have a "red" hue here, while clouds have a tinge of "blue".
On Sunday, January 20th, 2019, there was a supermoon and a total lunar eclipse visible in both North and South America. An Arctic air mass in the Mid-Atlantic/Northeast US made for very cold viewing conditions, but the air was also very dry which improved the clarity of the moon during this space event.
GOES-17 satellite imagery features a monstrous storm over the Pacific Ocean which is producing near hurricane-force winds (January 7th, 2019). Wave heights of up to 45 feet have been analyzed near this powerful system.
Known as the green “Christmas comet”, even the northern lights over Norway could not prevent it from being seen on Monday night, December 17th, 2018.
A GOES-East satellite image reveals the deep snow pack that still remains across much of western North Carolina and southern Virginia. Clouds can be seen off the east coast and over the Great Lakes, but clear skies over the snow pack allow for great viewing today, Wednesday, December 12th.
Since 13 September, European Space Agency’s Mars Express has been observing the evolution of an elongated cloud formation hovering in the vicinity of the 20 km-high Arsia Mons volcano, close to the planet’s equator.
In spite of its location, this atmospheric feature is not linked to volcanic activity but is rather a water ice cloud driven by the influence of the volcano’s leeward slope on the air flow – something that scientists call an orographic or lee cloud – and a regular phenomenon in this region.
The cloud can be seen in this view taken on 10 October by the Visual Monitoring Camera (VMC) on Mars Express – which has imaged it hundreds of times over the past few weeks – as the white, elongated feature extending 1500 km westward of Arsia Mons. As a comparison, the cone-shaped volcano has a diameter of about 250 km.
Mars just experienced its northern hemisphere winter solstice on 16 October. In the months leading up to the solstice, most cloud activity disappears over big volcanoes like Arsia Mons; its summit is covered with clouds throughout the rest of the martian year.
Hurricane Willa has strengthened into a cat 5 storm as of Monday, October 22, 2018 and it will actually play a role in a potential nor’easter this weekend by feeding energy and moisture into the Gulf of Mexico region. Hurricane Willa is likely to weaken into a category 2 or 3 storm before making landfall in Mexico over the next couple of days.
These spectacular lenticular clouds were seen in California on Sunday, September 30th, 2018. Lenticular clouds are stationary clouds that form in the troposphere, usually in perpendicular alignment to the wind direction. As air travels along the surface of the Earth, obstructions are often encountered. These include both natural features of the Earth such as mountains or hills, and man-made structures, such as buildings and other structures. These disrupt the flow of air into "eddies", or areas of turbulence influenced by these obstructions. When moist, stable air flows over a larger eddy, like those caused by mountains, a series of large-scale standing waves form on the leeward side of the mountain. If the temperature at the crest of the wave drops below the local dew point, moisture in the air may condense to form lenticular clouds.

The view of the California wildfires from the International Space Station (August 6, 2018).
GOES NOAA-20 VIIRS day/night band captures this “hot spot” associated with the CarrFire in northern California on July 28, 2018. The full moon provided ample illumination to see the smoke billowing from the wildfires.
The sky has turned orange around the Parthenon in Athens, Greece as a result of wildfires in the region. The winter was dry and high winds in recent days are fanning the flames of two separate fires: one to the west of the city in pine forest regions and to the northeast of the city in coastal towns.
