They scan the globe in pole-to-pole loops and feed important information into models for forecasting the most dangerous storms. But later this decade, a gap in these polar-orbiting satellites is foreseen. Could that prove costly for weather predictions?

It ended up a bit cloudier today than expected, but that has not kept temperatures down much. Highs near and just above 80 are well above average for the date, and with humidity levels running high, it certainly doesn’t feel much like fall. We’ve got some more mild times ahead for the rest of the work week. Enjoy -- if you’re into that sort of thing!

The NOAA weather satellite that tracks weather systems over eastern North America and the Atlantic ocean no longer has eyes on our skies.

There’s no way to know exactly if or where Isaac will ultimately make landfall in the United States or how strong it will be. Even a close call in Florida could result in flight cancellations, heavy rains, and other complications for the Republican National Convention. The good news is that forecasters now have a wealth of tools and an array of knowledge at their disposal that were almost unimaginable 40 years ago.

On May 2, 1982, a new cable network called The Weather Channel revolutionized television weather coverage and vastly expanded the reach of weather information across the U.S. Today, it’s celebrating 30 years on-air.

The winding currents of our atmosphere have never been easier to appreciate thanks to a new visualization project by Google computer scientists. Browse on over to hint.fm/wind and watch our nation’s streams of flow converge, diverge, accelerate and decelerate as they create our weather.

Starting this Friday, the National Weather Service (NWS) is upgrading the region’s radar, sited in Sterling, Va., to include dual polarization technology. This technology will allow meteorologists to see storms in a totally new dimension offering the potential to significantly improve forecasts, especially during flood events and severe weather.

Using a weather balloon purchased online, two 17-year old Canadian students launched a lego man on a dramatic mission 80,000 feet into the stratosphere. By affixing multimedia recording equipment to the payload and a parachute linked to GPS so it could be recovered (it was), the resourceful teens captured spectacular imagery of the journey.

A new policy put in place by the National Weather Service prohibits the agency from developing apps for specific mobile devices, such as the iPhone or iPad. Weather Service employees oppose the move, saying it would privatize a key function of the agency - the communication of its forecasts, watches and warnings - to private companies like The Weather Channel, which have already developed such apps.

As the Japanese nuclear crisis continues to unfold, the airborne spread of radioactive materials from the stricken reactors at the Fukushima Daiichi power station continues to be a key concern of Japanese and American officials. To help determine the path that any hazardous emissions are likely to take, scientists are employing specialized computer models, known as “trajectory models,” which can take into account factors such as winds and temperatures aloft to determine how high a parcel of air is likely to climb, how far it may go, and where it may be within certain timeframes.

Almost two years ago I asked the question, “Do Solar Storms Threaten Life as We Know it?” The answer then and even more so now could very well be a scary “yes” - even within the next few years - as an increase in solar activity coincides with the increasing vulnerability of technology-dependent societies to a powerful solar storm. Moreover, should there be a solar strike capable of causing widespread blackouts and crippling disruptions of satellilte and radio communications, it’s likely there would be little advance notice, and currently there is virtually no capability to shield much of the planet and virtually no planning on the books to recover from the potentially disastrous consequences.

It’s a little sad, but not surprising, to hear that after 70 years Verizon plans to pull the plug on telephone time and weather on June 1. How do you feel about the demise of 936-1212?
