This should also be the direct feed from the FAA, as that is what they use.
Not only will this decrease METAR latency by several minutes for some domestic
METARs, but this will also allow for new METARs that the FAA sends to be
available immediately after activation.
But note that this applies to KWBC METARS. Military observations on KAWN will
still need to have to be accounted for. I would just grab anything SA* or SP*
for WMO header capture, and then you likely don't have to worry about any
changes in the future.
