[python #OQJ-285928]: siphon issue

Greetings!

A little over a year ago, the NWS stopped sending out the N0Q (1km x 1 deg) 
product in favor of the "super resolution" N0B product (0.25km x 0.5 deg):

  https://www.weather.gov/media/notification/pdf2/scn21-96_sbn_super-res.pdf

If I modify your code to use 'N0B' instead of 'N0Q', I get data as expected. Of 
course, `validate_query()` then fails because we haven't updated our THREDDS 
server config to list the new products (ooops).

Cheers!

Ryan
