This code downloading a NIDS NST product:

from siphon.catalog import TDSCatalog
from siphon.radarserver import RadarServer
from siphon.cdmr import Dataset
from datetime import datetime, timedelta
cat = TDSCatalog("http://thredds.ucar.edu/thredds/radarServer/catalog.xml")
url = cat.catalog_refs['NEXRAD Level III Radar from IDD'].href
rs = RadarServer(url)
query_latest = rs.query()
now = datetime.utcnow()
query_latest.lonlat_box(292.9375, 235.0625, 25.0625, 52.9375).time(now).variables('NST')
query_latest_cat = rs.get_catalog(query_latest)
data_available = list(query_latest_cat.datasets.values())
data_from_thredds = Dataset(data_available[0].access_urls['CdmRemote'])

data_from_thredds.variables['textStruct_code8gg'][:]

results in:
