[LDM #SUM-958383]: Changed NCEP/AWC data

Brian,

[I drove your email into our support-email tracking system so that we have 
permanent record that others can find. Hope you don't mind.]

The product is already trying to be decoded by the GRIB2-handling code, so an 
addition to the relevant GEMPAK GRIB2 table "g2varsncep1.tbl" should suffice to 
process this new product.

> Hi Steve,

> NCEP introduced a new turbulence product that was previously grib1 but is
> now grib2.  When this product was activated on NOAAPORT, LDM threw the
> errors you see below.  This product is still active on NOAAPORT, so I'm
> betting you'll see the same thing.  The WMO header pattern is
> "[YZ]VW.[0-9][0-9] KKCI".  Is this something that will take a code change
> to fix, or will updated grib2 tables take care of it?
