Don't Worry, That Blimp Isn't Watching You Much 43
According to the Baltimore Sun, and despite claims by its maker Raytheon that the system is "performing well right now," the expensive tethered-blimp observatory called JLENS (for "Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System") seems to be mostly a boondoggle. The report focuses on the JLENS installation that was launched in Maryland last year. The Sun makes much of the flight taken by disaffected postal worker Douglas Hughes last April to the White House lawn, directly in the JLENS observation area -- the success of which (to be charitable) casts doubt on the effectiveness of the flying observatory system. Beyond its evidently low utility in doing its job, JLENS seems to be a brittle system, amplying its potential costs as well as its military vulnerability with grand, expensive failures as well as everyday difficulties: in 2010, "a civilian balloon broke loose from its mooring, destroying a grounded JLENS blimp that had cost about $182 million." The article lays out some political shenanigans, too: politicians in a wide range of states have supported the project, which has a nationwide footprint of contractors and possible deployment locations. From the article:
Within the Pentagon, Marine Corps Gen. James E. "Hoss" Cartwright, then vice chairman of the Joint Chiefs of Staff, came to JLENS' defense, arguing that it held promise for enhancing the nation's air defenses. At Cartwright's urging, money was found in 2011 for a trial run of the technology in the skies above Washington.
Cartwright retired the same year — and joined Raytheon's board of directors five months later. By the end of 2014, Raytheon had paid him more than $828,000 in cash and stock for serving as a director, Securities and Exchange Commission records show.

I have long maintained, that by dollar spent per enemy casualty, the US armed forces are most expensive and least cost-effective in the world. In terms of bang for the buck (pardon the expression), America is financed, overseen and managed by a collection of complete dolts. Sadly, their dumbness filters from the top downwards, so that a private has twice the common sense of a major.
America has not formally declared a war since 1941, but has somehow managed to lose quite a few anyway - Mission Accomplished!

What John Dolan knows about military weapons systems could fit in a thimble with room left over for his brain. That's the entire reason he needs the persona; he couldn't talk about military weapon systems and be taken seriously otherwise.

At the altitudes where such balloons normally reside, the weather is pretty stable. With no pesky land features to complicate things, the weather is mostly just influenced by whatever's already happening upwind. As for the aerostats themselves, they are surprisingly maneuverable at their normal altitudes, usually having just a few horsepower of motors turning a few small propellers. With so little air resistance, the craft can avoid inclement weather easily.
Even if a lighter-than-air vehicle is caught in poor weather, the majority of the effects are mitigated. It's a balloon. It moves with the wind, doesn't make a good conductor, and is usually unmanned. Unlike an airplane, it's not trying to fight against the wind, so the forces on the structure are greatly reduced. In turbulence, the outer bag flexes and accommodates any stress. It might get a little shaky for the instruments, but not unreasonably so.

These craft though are tethered and are only at about 10,000 ft. Sounds like the worst of both worlds to me. Cloud activity routinely reaches above 23k feet, and they're tethered so they can't escape or move with the weather. I'm sure you could design it to withstand the forces required, but given that they've spent almost $3 billion for only 4 prototypes (only two of which are currently in operation) its not looking very cost effective..

There's not much in the way of ballast in modern lighter-than-air craft. Aerostats control their altitude by adjusting their density. They control their density by inflating lift bags inside their outer shell. For weather-induced vertical movements, the craft doesn't need to do much of anything. It'll float or sink to its intended altitude naturally. As for the tether, it's plenty strong enough, and serves as an inertial mass to dampen the movement of the balloon.

There is a thing over the US that is for cruise missile defense?
Exactly how much of a threat are those in Washington? Considering exactly none of them have ever been fired in anger at the United States, it makes me wonder.
And what is this thing going to do about a cruise missile if it does see one? Maybe it is supposed to be connected to some kind of air defense, but the only way one of those is going to be shot down is if it is detected over the horizon.

You might note that the horizon distance is highly dependent on the height of the observer over the spherical planet. [wikipedia.org] That's the whole point of putting the sensors on blimps. Once detected, engagement can be managed with a variety of weapons systems; most likely by fighter planes on short notice standby.
