Default Who's Going To Be First?

I started this thread with tongue in cheek.

Note in the text that displayed weather is 5 minutes old (probably more than
that). A thunder storm can move just enough to kill you in that time if you
rely on these displays. See the following:

It would be nice to get satellite Wx to see the cloud patterns, like
streets. Is there anyway to get this now? Smart phones tend to not
work well above a few K feet AGL.


XM weather. Google it. Takes a subscription, but it's delivered by
satellite, so it will work no matter how high you are.

Eric, This sounded great so I just looked into this. It seems the only satellite product they show is "mosaic" and from the description it sounds like infrared view only. It says it does not show clouds lower than 5000 AGL so may not be useful for tracking cloud streets on all days.

Satellite Mosaic
"Displays cloud cover over the continental United States and hundreds of miles off its coastline. An advanced formula estimates cloud temperatures at various altitudes across the country and converts them into estimated cloud height. Clouds below 5,000 feet are so close to ground temperatures, they are not shown."

You need to come out West, where 5000 AGL is so low, your are picking
out a place to land :^)

I've never used XM weather, but a friend of mine uses it, and says the
cloud images are very helpful when dealing with thunderstorms. I don't
know if the resolution is good enough for cloud streets or wave bars. I
suspect not, since it seems to take the 1 km visible to see those, and
the IR resolution is 2km at best.
