I have just read the Senate bill at;
http://thomas.loc.gov/cgi-bin/query/.../~c109Wu4LQQ::

And at no point does it restrict access to NWS data.

What is does do, is curtail the from continuing to encroach on what had long
been the arena for private meteorologist in the U.S., with more and more of
their value-added products. As a creator of value added products,
I must support such a measure to stem the out-going tide of my income.

If I read the fine print correctly, it will also stop universities from
posting value added products too (at least I hope that is what it says).
