Eastern U.S. may see stormy, wintry weather pattern next week

The first storm, which could be particularly intense, is projected to take an inland track early next week, from the Gulf of Mexico toward the eastern Great Lakes. Such a track would draw up enough warm air for mostly rain along the East Coast. But interior locations in the Ohio Valley and eastern Great Lakes could see their first significant snow.

There’s some chance for a second storm to develop slightly to the east of the first one around Dec. 3 or 4, opening up the possibility for wintry precipitation closer to the East Coast.

The first storm: Early next week

An upper-level disturbance ejecting from the Desert Southwest will help spark the development of a storm system near the Louisiana Gulf Coast late in the weekend.

Computer models agree that it will tap substantial moisture from the Gulf of Mexico and produce heavy rainfall in the South and Southeast

Here’s Your Sonic Boom Weather Forecast!

Success for Aerion hinges on the ability of its planned AS2 business jet to fly in excess of the speed of sound over land without delivering a sonic boom. To do so, AS2 operators will have to account for, avoid and overcome weather conditions that could allow supersonic shock waves — the boom that humans hear — to reach the ground.

That means that AS2 owners and crews will need a sort of sonic boom weather forecast to be able to plan for boom-less flight over the U.S. or other territories.

Aerion says it has just the thing thanks to an agreement with micro-satellite operator Spire Global, whose weather data and forecasting capabilities will allow the AS2 to boom along over

Weather Service tells Congress radar gaps don’t hurt warning accuracy, but outside scientists disagree

Weather forecasters around the country strive to warn communities in advance of every tornado that touches down, each flash flood that is about to occur and each winter weather event.

One of the most reliable and costly tools at a meteorologist’s disposal for issuing watches and warnings is a network of 159 Doppler radars located across the country that provide detailed views inside storms. Radar helps meteorologists determine precipitation type and intensity, how much rain or snow has fallen, as well as the wind direction and speed at which precipitation is moving within a storm.

Using these radars, forecasters can spot the existence of a tornado by detecting airborne debris lofted by the twister’s circulation. They can track the all important

Weather on Jupiter and Saturn may be driven by different forces than on Earth

A trio of researchers, two with Harvard University, the other the University of Alberta, has found evidence that weather on Saturn and Jupiter may be driven by dramatically different forces than weather on Earth. In their paper published in the journal Science Advances, Rakesh Kumar Yadav, Moritz Heimpel and Jeremy Bloxham describe computer simulations showing that major weather systems on Jupiter and Saturn might be driven by internal rather than external forces, resulting in outcomes such as the formation of large anticyclones like Jupiter’s famous red spot.


Weather on Earth is primarily driven by processes that take place in a thin layer of the atmosphere near the planet’s surface. For many years, it has been thought that similar processes drive weather on other planets, such as Jupiter and Saturn. In this new effort, the researchers demonstrate that such theories may be wrong.

SpaceX’s Starlink still provides rapid internet speeds in bad weather

  • Users of SpaceX’s Starlink satellite-internet service said how impressed they were with download speeds in snow and high-speed winds on the Reddit Starlink community.
  • One user reported speeds reaching 175 Mbps in the colder air, which is 20 Mbps faster than usual.
  • The Starlink terminal even withstood a user’s 175 mph leafblower.
  • The terminal – or “UFO on a stick” – heats up enough to melt the snow on top of it. But some users said internet speeds drop as the snow initially builds up.
  • Visit Business Insider’s homepage for more stories.

SpaceX’s Starlink satellite-internet service gives users rapid speeds reaching 175 Mbps even in high-speed winds, deep snow, and freezing temperatures.

Users of SpaceX’s “Better Than Nothing Beta” test have posted pictures and videos on the Reddit Starlink community proving that the Starlink terminal still works in extreme weather conditions – and in some cases, it’s even faster.

SpaceX launch of crew on first ‘operational’ mission delayed by weather

By Joey Roulette

WASHINGTON (Reuters) – NASA and high-tech entrepreneur Elon Musk’s rocket company SpaceX announced on Friday a 24-hour weather delay of their planned launch of four astronauts into orbit for NASA’s first full-fledged human mission using a privately owned spacecraft.

The liftoff time slipped from Saturday to Sunday evening due to forecasts of gusty, onshore winds over Florida – remnants of Tropical Storm Eta – that would have made a return landing for the Falcon 9 rocket’s reusable booster stage difficult, NASA officials said.

SpaceX’s newly designed Crew Dragon capsule, dubbed “Resilience” by its crew, was rescheduled for launch atop the Falcon 9 at 7:27 p.m. Eastern time on Sunday (0027 GMT on Monday) from NASA’s Kennedy Space Center in Cape Canaveral.

The crew for the flight to the International Space Station includes three American astronauts – Victor Glover, Shannon Walker and the mission commander, Mike Hopkins, a

SpaceX-NASA launch postponed to Sunday due to weather

NASA on Friday said the planned launch of a crewed SpaceX vessel to the International Space Station (ISS) on Saturday had to be postponed by a day due to inclement weather.


“Due to onshore winds and recovery operations, @NASA and @SpaceX are targeting launch of the Crew-1 mission with astronauts to the @Space_Station at 7:27 p.m. EST Sunday, Nov. 15 (0027 GMT Monday),” NASA administrator Jim Bridenstine tweeted.

“Recovery operations” refers to the ships that have to be moved into place in case the mission is aborted after launch and the crew is forced to splash down in the ocean.

Sunday’s launch begins the first of what the US hopes will become routine missions for SpaceX following a successful test flight in late spring.

That demonstration flight in

NASA Delays Milestone SpaceX Flight Until Sunday on Weather

(Bloomberg) — NASA and SpaceX delayed the launch of their first regular commercial crew flight by a day because of weather conditions that could threaten recovery operations at sea if the Dragon capsule has to abort the flight during ascent.

SpaceX will send four astronauts to the International Space Station on Sunday evening instead of Saturday “due to onshore winds and recovery operations,” NASA Administrator Jim Bridenstine tweeted Friday after a readiness review.

The Crew-1 launch is now scheduled to blast off from Cape Canaveral, Florida, at 7:27 p.m. on Sunday, with docking at the station planned for 27 hours later. The trip will be SpaceX’s first regular crew rotation to the orbiting lab, three months after the company completed a high-profile trial run.

NASA has contingencies for crew rescue operations along the U.S. East Coast and across the North Atlantic if a mishap forces the Dragon capsule

How Location-Specific Weather Forecasts Boost Efficiencies For Ports And Terminals

This year’s unprecedented hurricane season has resulted in downtime for many operators in the liquid natural gas (LNG) industry due to damage from the storms. It is just one more set of risks being seen in what was already a difficult year, and is contributing to several proposed projects being delayed. These storms are a challenge for the industry to navigate as demand for LNG will rise by 0.9 percent per annum to 2035.

An inexpensive monitoring system with 3-D-printed parts and low-cost sensors might not last as long as a commercial one, but it can be just as accurate, researchers found.


Across the United States, weather stations made up of instruments and sensors monitor the conditions that produce our local forecasts, like air temperature, wind speed and precipitation. These systems aren’t just weather monitors, they are also potent tools for research on topics from farming to renewable energy generation.

Commercial weather stations can cost thousands of dollars, limiting both their availability and thus the amount of climate data that can be collected. But the advent of 3-D printing and low-cost sensors have made it possible to build a weather station for a few hundred dollars. Could these inexpensive, homegrown versions perform as well as their pricier counterparts?

The answer is yes—up
