Re:Solar constant is 1kW/m^2. No way around that.
If the Solar Impulse project is anything to go by, it's hopelessly dependent on good weather to be able to sustain flight. For example, if you were dealing with aviation on a regular basis, you'd know that there are these things called "upper altitude winds" which regularly reach speeds in excess of 100kts even at fairly low altitudes (~10000-15000 ft) and given that the Solar Impulse's cruise speed is around 35 kts, it'd simply get blown all around the place, almost like a balloon. At that point, you might as well just junk the idea of heavier than air flight and just stick your comms antennas on a solar-powered blimp. And given the atrocious coverage such a system would provide vs. space satellites, means you'd need probably like tens of thousands of those in constant upkeep, just to give you decent coverage. For global "satcom" phone coverage, it's much easier to just launch 20-30 small polar orbit satellites, which are on stable orbits and give you global coverage at the same time - and we've already done that. For internet access and broadcasting, just build radio masts, which are cheap as heck and require almost no maintenance, or a couple of high-power GEO satellites to cover a whole continent - and we've already done that too. And as for NGOs and high-altitude surveillance, what you want is a blimp, not an airplane.
Put simply, solar-powered airplanes are a solution in search of a problem. -
Training and Visualization
As a retired weather guy with over 25 years working with and training weathermen, this is one of the best tools I've seen. Applause!
Understanding fluid flow and visualizing it is not easy, but it crucial to meteorology because that dynamic drives and reveals the mechanisms that create the weather systems we track, such as fronts, storms, and so on. Given the tools seen are usually something like this (from ADDS) or this (from CoolWx), the WindMap does a much more intuitive job of showing the strength and patterns in merging flow.
So, well done! The only improvement I can think of for better use operationally would be an hourly looper of, say, the past six hours with a 3-4 second pause for each hour. This would let you track specific features as the day goes on. -
Re:heating element
Or, if you can somehow detect the snow, you could fully automate it. But doing it purely based on temperature would be wasteful because a lot of the time you have cold without snow.
Aviation (and I'm sure other applications) use "precipitation discriminators" in many of our weather stations to tell if it is raining, snowing, etc. I don't know the technical details of how they work, but they're used all over the place. No reason they couldn't be applied to the suggestion of only using the heating element when needed. Even with as little information as temperature/dewpoint spread, when it gets small enough we know to watch out for the high probability of icing.
You wouldn't need a station at every intersection. Hell, there are enough airports in Ohio alone with AWOS/ASOS systems that you could probably just use their data and err on the side of caution. -

You're going to have a lot of angry pilots...
You're going to have a lot of angry/annoyed pilots once they find out they can't use websites such as aviationweather.gov, duats.com, and duat.com just to name a few.
Yet another stupid bill brought to you by Corporate America(R). -
Re:What about the weather?
I think it's also worth mentioning the ADDS site. It is somewhat aviation-oriented, but is a great site with a lot of good weather-related information. http://adds.aviationweather.gov/

Re:Uh oh..?Sure go to the National Tranportation Safety Board website and go look up general aviation accidents and you'll see a huge number of accidents based on the weather.
The main cause is still the pilot though
Not checking weather
Not turning around when caught in bad weather
Then not being able to control his airplane due to his lack of planning, lack of training, and of course the weather.You want a high profile example of how weather kills. Do a search for J.F. Kennedy Jr and see why he crashed is airplane.
How do I know this well it should be obvious, I'm a pilot, well not quite yet a student pilot and a good 1/4 of the ground school revolves around weather.
But what has those companies in an uproar is not aviation, naval, or industrial weather reporting, but the weather chanel style weather put out to Joe Blow. The professional version have been avialable online for free for years and before that over the teletype and phone. The only problem is to the lay person they can be difficult to interpret. If they integrate the data into a simplified website the private companies would have a tough time competing.

Re:Mmm... weather...
A PLETHORA OF SFC AND UPPER LEVEL FEATURES BEGINNING TO SPAWN
Translation (as I can't find this text in Google, I'm assuming IA is Iowa, and that this was a recent advance bulletin regarding weather moving towards Illinois):
DEEP MOIST CONVECTION IN NRN IA, WILL EVOLVE INTO A MCS LATER
TONIGHT AND LIKELY MOVE INTO THE NRN PORTIONS OF THE CWA.
CONCURRENTLY... wtf is MCS? CWA?A lot of surface and upper level features beginning to spawn deep moist heat transfer in northern Iowa will evolve into a group of thunderstorms later tonight, and likely move into the northern portions of the area concerned by this bulletin.
See "A Comprehensive Glossary of Weather Terms for Storm Spotters," by Michael Branick, located here. Further resources are here and here though this list - and the terms they cover - are by no means comprehensive.
Take pretty much everything with a grain of salt, and try to cross-reference, as all terms aren't defined at all of the references, and some of them aren't what you're looking for. For example, Branick doesn't list "CWA," and AVWX lists it as "Central Weather Authority." In context of the bulletin you posted, "CWA" means "County Warning Area," something none of these references mention. A County Warning Area encompasses multiple counties, often across several states. Go here and find the color-coded region on the map that represents your closest big city; that's your approximate CWA.
Chicago would be LOT (Lockport, airport code) in Central Region HQ, or http://www.CRH.noaa.gov/LOT . Bookmark that, if you haven't already, and watch the county map the next time there's severe weather in the area. Reload every couple of minutes, and you'll know about any watches, warnings, or statements affecting local counties. Fascinate your friends and family - and who knows, possibly save their lives - by IM'ing "Tornado Warning!" 2 minutes before the sirens go off and 3 minutes before the TV jockey passes the warning along. Fuck the TV weather, noaa.gov is the shit.
I will admit to sharing your perplexity as to why NOAA doesn't issue more "English" warnings. The only thing I can come up with is that in some cases, time is of the essence, and keeping the transmission as small as possible makes it faster to type and transmit. I'm not sure that quite explains it, though; as when EAS activation is requested for a tornado warning here, all of the cooperating radio stations broadcast a robotic text-to-speech voice reading a quite English version of the warning.
The bulletins are translated into understandable English at some point before they're broadcast to the public, so why they can't be written that way to begin with, I'm not sure. Maybe it's because NOAA/NWS has outsourced to India? >:)
