Correct NOAA WX weather product URL regression

One piecemeal use of the retired weather.noaa.gov/pub URL was missed
in the correlate() function, causing it to be reintroduced for
zone-based reports (such as forecasts) in a subsequent correlation
dataset update. Correct the invalid URLs in the zones file, and
update the correlation routine to embed the correct and working
tgftp.nws.noaa.gov hostname instead.
