	It's also possible to get a weather forecast via HTTP but without
	a /browser/ -- thanks to the GFS data availability via OPeNDAP.

	Suppose we're, for some reason, interested in Moscow, ID.  As of
	this writing, [1] points to [2] as the latest available forecast.
	Now, I have GrADS [3] installed with NetCDF and OPeNDAP support
	linked in, which I can use as follows.  (The place coordinates
	are per [4].)

$ grads -lb 
...

	Select "plain text" output, for easier inclusion into this post
	(although GrADS is perfectly capable of graphical output as well):

ga-> set gxout print 

	Select dataset:

ga-> sdfopen http://nomads.ncep.noaa.gov:9090/dods/gfs_0p25/gfs20180917/gfs_0p25_06z 

	Select whole range alongside the time axis (use > query file to
	find out the limits; in this case, that'd be 2018-09-17 6:00 UTC
	through 2018-09-27 6:00 UTC -- at 3 hour intervals):

ga-> set t 1, 81 
Time values set: 2018:9:17:6 2018:9:27:6 

	Select specific spatial point:

ga-> set lat 46.73239 
LAT set to 46.75 46.75 
ga-> set lon -117.00017 
LON set to -117 -117 

	Get surface temperature in degrees Celsius (slightly reformatted
	for readability and time line added):

ga-> d tmpsfc - 273.15
