As the U.S. Thanksgiving holiday approaches this Thursday, November 27, NOAA's GOES-East and GOES-West satellites are keeping a weather eye out for storms that may affect early travelers. In an image from Nov. 25, the satellites show an active weather pattern is in place for travelers across the central and eastern U.S.

NOAA's GOES-East satellite provides visible and infrared images over the eastern U.S. and the Atlantic Ocean, while NOAA's GOES-West satellite covers the western U.S. and Pacific Ocean from its fixed orbit in space. Data from both satellites were combined at NASA's GOES Project to create a full view of the U.S. on Nov. 25 at 11:45 UTC (6:45 a.m. EST). The image shows clouds associated with cold front stretching from the Gulf of Mexico over northern Florida and along the U.S. East coast to eastern Canada. Clouds associated with another area of low pressure are in the northern Rockies and northwestern U.S.
To create the image, NASA/NOAA's GOES Project takes the cloud data from NOAA's GOES-East satellite and overlays it on a true-color image of land and ocean created by data from the Moderate Resolution Imaging Spectroradiometer, or MODIS, instrument that flies aboard NASA's Aqua and Terra satellites. Together, those data created the entire picture of the storm and show its movement. After the storm system passes, the snow on the ground becomes visible.
NOAA's National Weather Service Weather Prediction Center said "a storm system will develop off the coast of the Carolinas early Wednesday (Nov. 25) and strengthen as it moves rapidly up the East Coast Wednesday into early Thursday (Nov. 26). Heavy snow is likely to begin in the central Appalachians early Wednesday morning, spreading northeast through the interior Mid-Atlantic into New England by Wednesday night. Winter Storm Watches are in effect for these areas."
For travelers in the western U.S., the Northern Rocky Mountains are expected to receive more snow from the north side of a stationary frontal boundary. South of the boundary rain showers will affect the lower valley. The National Weather Service calls for cold weather to continue in the northern Plains and Upper Midwest as a Canadian surface high pressure rules the weather. The U.S. Southwest will experience nice weather for mid-week.
In the Pacific Northwest, the National Weather Service noted that a warm front will bring rain, heavy at times, to the Cascades today and tonight. There will be a break in the heavier rains on Wednesday, then another period of heavy rain for the Cascades Wednesday night through Friday morning as a cold front slowly drags through the area.
NOAA's GOES satellites provide the kind of continuous monitoring necessary for intensive data analysis. Geostationary describes an orbit in which a satellite is always in the same position with respect to the rotating Earth. This allows GOES to hover continuously over one position on Earth's surface, appearing stationary. As a result, GOES provide a constant vigil for the atmospheric triggers for severe weather conditions such as tornadoes, flash floods, hail storms and hurricanes.

FAA Seal
The Federal Aviation Administration (FAA) announced on Sunday that a  airspace upgrade for the Washington, D.C. metro area would be in place in time for the holiday travel week. The FAA said this will improve the efficiency of air travel in this area.

 Secretary  said this upgrade highlights the difference the federal government is making in air travel. He also said this upgrade will improve on-time performance and reduce fuel consumption and emissions.

FAA administrator Michael Huerta said with the busy holiday  season approaching, it is important to get travelers to their destination safely and on time.

The D.C. metroplex now includes three  (OPDs) that allow aircraft to descend smoothly to the airport, as opposed to a staircase-style decent. This reduces fuel burn during decent because every time an aircraft levels off, it needs to burn more fuel for each step in the descent. The FAA said it will benefit three major airports in the area:  (DCA),  (IAD), and  (BWI). 

In a video describing the OPDs in D.C., Brian Townsend, a tech pilot and captain for American Airlines, said this gliding down approach will be more environmentally friendly than the traditional approach.

This initiative at the D.C. metroplex involves collaboration by , , and  and some labor unions, and is also an effort to improve efficiency for aircraft arriving and taking off from surrounding airports such as , , and other small airports in this region. 

The agency announced yesterday it has finished the work for the NextGen system in D.C.  NextGen is a replacement for the ground-radar-based system that has been in operation since . They also completed a NextGen metroplex project in North  last week. The NextGen system is expected to cost billions of dollars to implement and the FAA funding is expected to expire in late 2015. Lawmakers, however, are holding hearings to possibly extend the funding window next year.

NASA is also conducting studies of the NextGen System. Researchers are using a brand new laboratory to test NextGen's operations with simulated flights. They plan also to put  into the .

According to the , a storm system originating over the  flowing to the Northeast region of the U.S. may affect travel this week, bringing heavy snow, rain, and winds.
